Maya python get top most parent transforms. I'm getting crazy reading the API classes (MDagPath, MSelectionList, MFnDependencyNode) and methods which would achieve that the first would be to find all vertices position, fast in python api in maya; the second one is comparing the distance between N points, really fast with numpy; for the second step i would recommend writing your own C module which can call in python. format(cv) cmds. When in my previous code, listConnections() returned a list of transform nodes connected to the shadingEngine nodes, selecting the shadingEngine node using these 2 new methods above, Maya actually the last one is pure maya stuff, all maya commands take in a list as last unnamed variable, this si the selection you work on. It should now match the line you drew. To answer my own question, I had to convert the UV indices to Vertex indices per shell. ls(obj Under Python, there is no concept of argument ordering, so the items are returned in a dictionary keyed by the name of the flag. I somehow need to get a list of all elements/sub meshes of a mesh inside of Maya and afterwards apply a randome color to each. getComponent(0)) [x. How to select vertices, then convert to face selection with Python? 2.

Definitely the most advanced tool I’ve tried to write First off, I don’t know how to get the mesh data from a selected vert. Here's how you use cmds. That's why its so easy to mess up a model with construction history if you go 'upstream' and change things that affect the model's component count or topology. import maya. I want to get the index of the vertices I’m selecting. How can I get or generate a list of indices of the selected vertices in a Python script? I find the Blender Python API reference utterly confusing to navigate, and Google mostly points to outdated APIs. # Python import maya. But Im running into some problems. - bm_componentToJoint. Setting the color is as simple as passing in the RGB values you want: ls -type (or cmds. However that won't know why the mesh changed: for example it will fire if you rotate a vertex selection instead of moving it. OpenMaya as om from maya import cmds def get_vertex_normal(mesh This only shows up in the python 2. Ask Question Asked 7 years, 8 months ago. 0 api docs: Selection lists have a getcomponent radius=30) mc. xform(vertex, ws = True, t = True, q = True) print In MEL, the values are returned in the same order as the flags are set.

After the creation of these elements I want to get the user the possibility to select some of these object and though a button to delete itThe problem is that I don't understand how to get the name of the object You can try out OpenMaya. Under Python, there is no concept of argument ordering, so the items are returned in a dictionary keyed by the name of the flag. OpenMayaAnim. Maya script that creates joints on each selected vertex or at the center of each selected edge or face. 1 How to list the vertices over a selected edge in Maya via Python. i am looking for a short script that returns the uv coordinates of all vertices in a mesh. Shifting Character Proportions. Selecting faces supports a couple of forms: Just building on Gwenn's great answer, If you are in Edit Mode, all the vertices may appear selected. Each point of the bound geometry can be affected by any number of joints. cmds as mc selection = mc. translateY', 12) Share. However I'm unaware of a way to elegantly get that information. So the algorithm would be: get a position tuple for each vert; make a dictionary (position: vertex) for all the verts on the 'left' (or 'up' or 'back' etc hi, let say you know the the vertex, here a command that would help. Its faster for maya to actually do it like this than to, set (setting selections is quite computationally intensive) then querry the global selection list. Thanks guys ! Exactly getUV(uvSet=None) -> [float, float]getUV(faceId, uvSet=None) -> [float, float] Get the shared UV value at this vertex. pymel how to get right type of selected node. r/opengl. OpenMaya.

The analog for useful Freeze Transformations command in Python is If you ever had to recover vertex positions of a mesh object, you probably crash yourself against the xform command and his legendary slowness. In maya's documentation, it shows how to use uniqueTag and selectUniqueTagItem, which I was able to get working properly but its not what I am looking for. color attribute. It works perfectly on a single selected object using this code: import maya. answered Jul 14, 2021 at 6:18. getActiveSelectionList() geo = om. active. In particular, if the specified objects are members of a black-boxed container and are not published as nodes, Maya will not select them. The below script will enable a panel in the 3d viewport hello, i know this is probably pretty easy, but i couldnt find it in the docs yet. OpenMaya as OpenMaya import maya. vtxFace[0][0]', r=True ) # Get the edge that originates at the selected face vertex print cmds. The AE often presents fake attributes which are used to calculate the real values -- for example, cameras have an angleOfView in the attribute editor, but setting it actually changes the focalLength attribute; I want to get a shape/mesh object under a transform node active in Maya. If you just want the face alignment, you can position your object and then create and immediately delete a normalConstraint. active_object. Hey hey! I’m trying to create a weighting tool that lets you select 2 verts, hit a button, select another vert, hit a button and it will apply the averaged out influences from the first 2 verts to the last one. I'm pretty new to scripting with python, so I'm having a hard time finding which command of many will actually apply my new material to my selected faces. vertices: vert. vertexIKnow = "pCube1. I am currently using Maya's standard cmds, but it is too slow. :baffed:. polyListComponentConversion( fvf=True, te=True ) # Result: pPlane1.

I've already tried to use bpy. vtx[5]" shapesOfTheMesh = cmds. In Python, returns the object's number of selected vertices as an int -worldArea(-wa) returns the surface area of the object's faces in world space as a float Create a plane that matches that line you have --> select your vertices and select scale --> set your pivot to edge of the plane you created --> scale the vertices flat. 64, I have a mesh in edit mode with some vertices selected. The docs mention that it will only transfer weights from selected vertexes, so in this example I simply select all vertexes. uv) But unfortunately the coordinates I'm trying to find a blendshape deformer from a target mesh in the python maya api. core as pm. Let's say I save these edges like this: edges = pm. I can't figure out how to get the map over so I figured if I can get the vertices of sphere2 closest to a vertex in sphere1, I can apply that vertex value to sphere2's vertices. This is my getter: mesh = cmds. Maya get vertex by position. 0. filterExpand(sm=34) # sm (selectionMask) = 34 looks for polygon faces. Most of the stuff I found on the internet is a bit hacky and doesn't end up working well. Ultimately I'm trying to make a softMod at a selected vertex, and have these controls created to animated the effects. cm. I don't see a method in the MPlug class which returns an MVector object; that would have allowed you to get all 3 values in the translate attribute in one call. object. Maya Python: Query selected vertex world position Get the mirrored world position (ie. It aslo costs less memory overhead as its one item in undo stack. I think my problem is that I don’t know how to append my list over to an Sets are used throughout Maya in a multitude of ways. . They all share the same number of vertex, but the names are different. 1 Mayavi curved arrow between two 3d points. Sometimes when trying to figure out a particular function, I will look at both the C++ and Python documentation. When selecting multiple vertices, it creates as many locators as selected list items, but they are all created at the first item in the list. tracker. OpenMaya as om sel = om. Hi. MSelectionList() OpenMaya. I'm trying to create a tool in maya that checks if the uv shells are overlapping and it's turning out to be a bit of a challege. 0, 0. ls(flatten = True, orderedSelection = True) cmds Python for Maya: "Object's name is not unique. News, information and discussion about OpenGL This seems an absurdly simple question, and I feel embarrassed for asking it, but: How do I list all vertices in a polygon mesh? i. setWeights(self. cmds as cmds # To set the rgb channels of selected vertices: cmds. selected_verts = [v # Python import maya. MSelectionList() selectionList. I'm sure this is a total noob question. (31 = poly verts, 28 = nurbs verts, 36 = sbds verts) Python examples import maya. So you can get all geometry shapes with ls -type geometryShape, since geometryShape is the node from which all other kinds of geometry derive. I can use MItMeshVertex to iterate over the vertices from a mesh or vertex selection, but not from a face or edge selection. Maya python aswell you can use the filterExpand -sm 31 -sm 28 -sm 36 to return all the selected vertecies and ignore any selected things other than verts. OpenMaya as ommSel = om. e[0] # Get both edges that Hello, I was hoping to find some help with this. A possible way to handle this: Get an MItMeshVertex iterator over your selection set, then for each item in the iterator, MItMeshVertex. Right now I'm just trying to get it so you highlight the vertices of an object, run the script and it creates curves Skip to main content. cmds as cmds # Gets all edges of selection regardless of component type or object mode edges = cmds. Example of how I They are unicode strings ( u'xxx') but that's OK - Maya accepts those interchangeably with regular strings: you can safely ignore the Unicode-ness of the strings and you don't need to go out of your way to make your own strings into Unicode. vtx[1], # Clear vertex selection. It just needs to go into a list properly. . 0. add I selected four vertices, the two poles of each sphere. pPipe1. ls(sl=1)[0] vertices = cmds. pointPosition( sel[ 0 + 1 ], w = 1 ) fol = cmds. How to access name of a specific vertex in graph (python-igraph) 5. How to list the vertices When enabled the indices of selected vertices or edges or faces are displayed depending on selection mode. Switch to Object Mode so the vertex selection gets updated. data print(uv[0]. f[10]") # Extrude a random face. 3, 0. filterExpand(sm=31) I wrote a simple script that stores vertex joint-skin values in a list and applies them in the selection order, meshSkinCluster = "" vertexWeightList =[] # get all selected vetices in order verts = cmds. If you dont know how to get to the set I am trying to create a script that once the objects are selected it will create another object, for example if there are more than 50 objects selected it will calculate that and make a sphere if there are between 25 and 50 selected it will make a cube if there are 10 - 24 selected it will make a cone and under 10 will make a torus. vtx[72:73,102,105,133,136,165:166] but I don't really understand the . cmds. cmds as cmds posX = posY = posZ = 0 selection = cmds. polyListComponentConversion(toEdge=True) A simple way to work with selected vertices: import maya. Vertex positions will be inserted into the given array and will be indexed using face-relative vertex IDs (ie. Snapping an object to another object vertex in Maya over Python Script. This has been tested with a sphere and 2 old joints to 2 new joints. The skinCluster command is used for smooth skinning in maya. I've noticed that I get different results when using the python API instead of the maya python commands. select(tsphere) sl = sorry if it not clear enough. pt[:][:][:]',r=True) When true, UV values on translated components are projected along the translation in 3d space. cmds as cmds targetCurve = 'curve1' # Curve to put clusters on curveCVs = cmds. Get the UV value for the give facen at the current vertex. 4. getAttr OBJECT. Preferably in Python. I'm trying to extract the vertex normal of a mesh object at a particular vertex. polyColorPerVertex( g =0. pntx". 0 Python With Maya Selecting Object and Rotating It. setAttr('pSphere1. I got this UV map, and I want to set the position coordinates for all the four vertices to x=0. It uses the API to get bounding boxes for all the uv shells in an object (note -- it should be a mesh shape object , I didn't add any checks). You almost got it. grow selected area and subtract the selected from the list with select border. joint(p=(-3. vtx' which is what you'd get from selected verts. ConvertSelectionToUVs() UVValues = cmds. So far I've created the material, created a shading group for the material, connected the material to the shading group, and changed the colour. Args: mesh_name (string): Name of mesh to find I'm trying to figure out how to select vertices through the Maya Python 2. Hey guys, I’m trying to learn the Maya Python API, my first attempt is to create two functions to get and set vertex positions on a mesh. Maya get vertex normal with polyNormalPerVertex upvote r/opengl. from maya import cmds vertex = cmds. cmds. ls(sl=1) # Lists the current selection and # stores it in the selection variable polyFaces = cmds. Select All apart from objects with specific name in Maya using Python. How do you apply a material to selected faces in Maya using Python? 1. I'm using the Python API for this, but if you know C++ and how to compile it with Maya you are at a huge speed advantage, especially when iterating over a ton of components. This video is a quick tip for listing and getting selected objects in python in maya. Either my computations are wrong or the center of I need to get all the selected vertices and store them in an array so I can loop through and find out information about each vert. Is there's a way to get the indices properly from a Pymel/Maya API function? How to list the vertices over a selected edge in Maya via Python. ls(sl=True) for all in selection: mc. outMesh attribute of the object to fire a script when the mesh is edited. 0 How to list the vertices over a selected edge in Maya via Python. ls(sl=1, fl=1): print vertex. or this way using Python command: import maya. In red is the "center" of this vertices, where Maya place the default pivot, and in blue is the centroid as I computed it. Hope that's what you're If you just want to assign a new color to the existing shader(s), it's a simple setAttr(). MGlobal. cmds as cmds sel = cmds. The issue are the values you are setting to the follicle's parameterU attribute. polyEditUV( query=True ) print str( UVValues ) Here's how to set the UV's of a selected vertex: import maya. Maya isn't built around the idea of hi, I am trying to get connected vertices from a meshFace. ConvertSelectionToUVs() What I want to do is a lookup or trace from the locator in negative or positive y until it hits the polyPlane and return the position of the closest point/vertex/uv/ I imagine this have been done one million times but the only I want to apply the same cluster that's affecting sphere1 on sphere2 with the same map. uv_layers. polyNormalPerVertex( rel I'm trying to get the coordinates for the selected UV vertices with this script: import bpy mesh = bpy. node, component = selection. skinFn. The extent to which each joint affects the motion of each point is regulated by a corresponding weight factor. filterExpand(sm=32) From here, I can just select the first edge, and get the object by splitting the unicode string: Create a curve at selected vertex in the direction of the normal maya. data, without looking for the mesh in bpy. This is hopefully trivial for the Blender scripting pros. Hot Network Questions Puzzle: Defeating the copycat challenge Meandering over ℤ Efficient way to get selected vertices via python (without iterating over the entire mesh) 0.

Both of which I chose to use the Maya API and forewent Maya Commands completely for performance reasons. This attribute's range is from 0 to 1 (yes you can set above 1, but shouldn't), and you are passing values way beyond 1 that make them all clump together on top. cmds as cmds selection = cmds. I’ve managed to get the positions and output them to a list, but what I havent figured out is how I can pass that list to another function to set the positions. getComponent(0) # We will use an iterator specifically designed Given a contour of selected faces, is there a simple way, My approach so far, since in my case all the vertices are on a sphere with a given radius, is to calculate every face's spherical coordinates to reduce the problem to 2d If you ever had to recover vertex positions of a mesh object, you probably crash yourself against the xform command and his legendary slowness. vtx[242]. Set custom location for import/export helper. If there is an easier way of doing this, I am all ears. cmds as In this post, I purpose a piece of Python script using the Python Maya API that allows you to faster recover the list of all vertex positions of an object. ls(selection=True) vertex_pos = cmds. 3.

Default is false. 4) ) # To set just the "x" value of normal of selected vertices: cmds. Any help would be appreciated. The newer OpenMayaAnim returns the values rather than setting them in-place, so if you want the old values back, you need to do oldValues = self. I'm in Maya and I need to select a whole bunch of objects, then create a joint that is parented under each of those objects. format(vertices[0]), lock=True) Retrieves the positions of the vertices on the current face/polygon that the iterator is pointing to. if you want a script to display this in the script editor (using a python tab) you can use this for a single vertex This will print out the vertex position in worldspace, this is the same info from the component editor. OpenMaya as OpenMaya # Get selected object mSelList = OpenMaya. I'm looking for a python function or script which could check the borders of all uv shells in the scene, The scripts I found are mainly used to find all uv shells in a selected object. How to retrieve the created vertices of cmds. The maya python API call (gives me a different result): # empty selection list selectionList = om. Getting rotation with the What is the python way to select vertices of a mesh? I've tried: for vert in obj. Modified 7 years, 8 months ago. I have a script where the user selects a vertex, and should store the name of the mesh that vertex belongs to. When I run the code I don't recieve any errors and almost everything works as intended, Python With Maya Selecting Object and Rotating It. 2, 0. getAttr("{}. OpenMayaAnim as OpenMayaAnim #Name of our targetmesh. My step was to get difference beetwen pivot orientation before and after pivot bake and next step is to add this difference to normal value. They are inside groups and I want to locate any of them which any coordinate is different from 0 (translation, rotation,scale) import maya. I'm not sure what commands I should be looking . joint() However I would recommend not trying; the vertex order is basically arbitrary and there are many different thing you can do while working with a mesh to cause them to re-order. polyNormalPerVertex( x=. translate(value=(0,0,0)), but this moves the vertices I'm trying to write a simple script that draws curves between selected vertices. I want an Open Maya getter and setter for locking a vertex's pnt attribute. badcat July 20, 2015, 6:33pm 11. getActiveSelectionList()mDagPath, mObj = A simple way to work with selected vertices: import maya. polyListComponentConversion(toEdge=True) cmds.

Get all vertices individually I know how to get vertices, edges, etc from a selected mesh, but how do you find the opposite? If I have one vert selected how do I get the entire mesh in python? Here’s a python function that does what you want I believe. ops. ls(sl=True)#here you get the selected vertex mc. Unfortunatelly it did not help. So far Ive managed to get the vertex ID's of a mesh but I've struggled to get the corresponding uv ids. polygon. I was trying to follow this tutorial to figure it out in MEL, but unfortunately when I try it, it just gets me all of the attributes instead of just the selected one. meshes; Code: mode = bpy. Similar questions have been asked, but never seem to get a Specifies that the same selection rules as apply to selection in the main viewport will also be applied to the select command. py Skip to content All gists Back to GitHub Sign in Sign up You get the selected components, find the skinCluster they belong to, get its influence and weight list, do something to change that list, and then set the weights again. Convert plane normal to tube orientation with python in Maya. I need it $\begingroup$ In your first line you retrieve a vertex from the active object's mesh, in the second line you retrieve the uv layer from the active object's mesh, and you don't need to add '. how to draw curves from vertex to vertex in MEL. The other way is just to check the selection for the string '. Vesion1 (Using Boundary It acts on the selected vertices. I guess it should be pretty straight forward short MEL script - select vtx nr 5 for all selected objects, but my MEL skills are It is working ok, but I am curious how I can create the circles in this case being used as controllers but with their 'center' attribute relative to a selected vertex. I want to select a vertex and see its position in world space, so i can copy parts of the x y or z to other vertices. ]; OBJECT is the name of your poly object and VTX No. The authoritative names are the ones in listAttr; the names you see in the UI are not reliable because an AETemplate can override them in any way it wishes. I was wondering if this information can be obtained through the rich selection. It's printed out nice, e. * faceId (int) - Index of the required face * uvSet (string) - Name of the uv set to work with I should have been more specific with what I want to do. thanks! Following is a simple sample (with some comments): Try it out with different kind of objects and components selected. I need to get the attribute from a key (or keys) selected in the graph editor. polyExtrudeFacet("pSphere1. select(d=True) cmds. getConnectedFaces to just get the connected faces, and store them in a set. (Maya will put the list based on the face_index number, which is not what we want) To clarify, the face index does not need to be changed itself. sel = Good Evening again, 😮 Is there an easier way to get all selected faceId's WITHOUT iterating over the face vertices where you always get 4 duplicates because of the faceID function which always returns the face id for the current face vertex ? import maya. What you are refering to as the "index" of the uv map is its name itself, there is not way you will have a correlation between a mesh's vertices index and a mesh's UV_layer There's not a one-liner way to do it. Q: In Blender 2. Like in this example: I have selected a vertex on my plane and its id is 8 and now using its UV space The easy way is to create a closestPointOnMesh node an connect it to the worldMesh attribute of your mesh. 2 returns all UVs inside specified shell(for the current map if one is not specified), use activeUVShells to get shell indices for current selection, use uvShellIds to get shell indices for specified faces or UVs Is there a way in MEL or Python in Maya to get one object's position in the coordinate system of MAYA Python: getting the position of selected object using matching the bounding boxes of two different objects. In this I go through the makeIdentity function. Viewed 2k times 0 . I'm new'ish to Maya, but one basic feature I've still not found is any way to select all connected faces/vertices. usually uv coordinates are for each vertex on each face, so a vertex can have multiple coordinates, but in my situation this isnt the case. My example shows the results for vertex 2 on pCube1. """ Gets all the vertices that are below the given height (y-axis). a poly sphere) in Maya, when calling getActiveSelectionList method, it returns a transform node, not a shape/mesh one. 0)) Maya, Python, How do i get the name of an object based on vertex selection? 0 Get the mesh name from the selected vertex. Every shader has it's own attribute set, so the exact values you need to set depend on the type of shader you want, but for common cases (lambert, phong, and blinn) it's just the . The only wrinkle is that there's a bug in Maya 2016 (not sure about others) where the normal value coming back from Python With Maya Selecting Object and Rotating It. data uv = mesh. * uvSet (string) - Name of the uv set to work with. polyNormalPerVertex( xyz=(0. createNode( 'follicle' ) cmds. I ended up making a version that worked using boundary vertices and one that assumed paired vertices on both meshes would be in identical global space. Actually this is where by brainstorm stopped) import maya. mSel = OpenMaya. ]; and this will give you the local co-ordinates of your selected vert. Get list of reference nodes In Maya using Python API. cmds as cmds # create some objects cmds ( newSet1, noExpand=True ) cmds. But getting just the pPipe1 transform node name doesn't seem super straightforward. The topological symmetry has already the mapping of the left and the right side of the vertices. Select Subobjects in maya python. In my textScrollList, its appending a variable which contains a list. cmds as cmds cmds. cmds as cmds def Maya components do not have persistent identities; the 'vertex id' is just the index of one entry in the vertex table (or the tables for faces, normals, etc). Calculate the Normal of a vertex in maya with Python. mode # we need to switch from Edit mode to Object mode so the Yeah, that is essentially what I am doing for transform nodes, but components have to be handled separately, which is annoying. Any suggestions? I’m concerned that using MItMeshEdge and somehow EDIT2: Thanks to Theodox and hundreds of searches for the help. The flag must be used at least twice to generate a valid command. If I select and object (e. How to list the vertices over a selected edge in Maya via Python. simple example would be having a TestBox Object and getting Looking for a function which returns a list of all UV shells from a selected object. (Check the list in the link for ways to refine this by picking different types and subtypes) To get the transforms, add a listRelatives -p. Also, I noticed that when selecting components (vertices, for example), Maya does not update the manipulator context with their average position, but rather, it appears to use the center of their bounding box. Maya – Select objects in viewport via Python. index() for Maya, Python, How do i get the name of an object based on vertex selection? 4. Follow edited Jul 14, 2021 at 11:05. select( newSet1 ) cmds. It binds the selected geometry to the selected joints or skeleton by means of a skinCluster node. 2. will return only the selected vertices and nothing else. i'm new How to list the vertices over a selected edge in Maya via Python. e. This will contain # all the vertices of from maya. ls( selection=True ) # Select the members of a set cmds. polyColorPerVertex 82K subscribers in the Maya work with 2020 and later import maya. vtx[VTX No. context. Members Online. Im using Maya to perform a certain task on selected edges. g. cmds as cmds # To set the xyz values of normals of selected vertices: cmds. When using maya's ls command when I'm selecting vertices and I want a list of the vertices I'm selecting, how can I use the type option so that I only get the vertices of a mesh? Something This python example loops through each individual vertex from the selection. You're using import maya. I'm testing to see how much of a performance boost I can get when using the API. In Python, if only one item is requested, then it will not be returned in a dictionary. -Z or -X) Create a closestPointOnMesh node with the mirrored world position as the input, and mesh as inMesh Query the closestVertexIndex result to get the nearest vertex (then delete the node when done) # Select vertices or mesh, then run script import maya. Looking to try and deal with what looks to be vertex normal issues causing these rivets to appear dark - I've used the set vertex normals tool to try and get the top faces on the rivets to look flat instead of curved, but because these are on a The first thing I would do is build a face relative coordinate system for every mesh face using the average face vertex position, face normal, and world space Y axis of the mesh's transformation. selection = om2. Currently creating a tool in the C++ api that performs vertex color operations - would like the user to be able to select a mesh, face, edge or individual vertices. Fastest way to get vertex positions (MEL) I have an nParticle object with 120k particles and a corresponding deforming mesh with 120k verts. " Here's how to return the UV's of a selected vertex: import maya. It's better not to use Reset Transformations command for your Cone from Modify main menu, 'cause pivot point goes back to its initial place. cmds as cmds # Convert the vertices to envolved poly face(s) and list results h=1, sx=1, sy=1 ) cmds. I'm a long time max user, new to maya, so this is a basic question, that is vexing me. selection = A simple approach is to get a hash value - a simple comparison operation - for every vertex that is identical for two verts which are symmetrical. select(clear=True) I'm using cmds here but you can also switch it to pymel if you like. When false, the UV values will not change for a selected vertices. So after short brainstorm I decided to try another way and get vertex normal value in world space directly. data[0]'. Ask Question Asked 5 years, 11 months ago. Using bpy in a standalone python script dies when rendering. targetMesh = "pSphere1" #Add selection. MSelectionList How to find matching vertices in multiple maya meshes. transform. Python igraph vertex indices. dag, self. Hi! I need to select multiple object vertices. ls(sl=True) #create empty list for new very good idea to use long names (ls -l) for everything: that way you can sort them using plain old’ python list sorts and be sure you get the hierarchy you expect . cmds as cmds import pymel. Selected Vertex into Edges Selection in Maya API? 4. 0,-12. select(sel)#if you run this you will see that the selected vertex are diferent from the ones you made the merge. Primarily didactic, these I can't properly store all my vertices into a list. Based on Jaroslav Jerryno Novotny's answer here. Modified 5 years, 11 months ago. Improve this answer. How do you select vertices in a maya python ls command? 3. Center object pivot with world center after combine. getActiveSelectionList(mSelList) sel = I'm trying to write a code that creates hair follicles in Autodesk Maya at the selected vertices, my code works, but it creates all the follicles at the same vertex when I have more than one selected. MItGeometry(*sel. ls) use the maya node hierarchy (as laid out in the docs. How to get the name of a selected Object Python Maya. 5 (in the center of the green pixel). Luckily tuples - NOT lists!! - are hashable. append(x) for x in indices] #there might be a better solution for initializing a MIntArray with an tuple. select( 'pPlane1. all i need is one pair of coordinates per vertex. This doesn't work when selecting objects (say two spheres) and it just creates a locator at the origin. My first question is how to access to list element? The returned list is >>>pPlaneShape2. Getting rotation with the distanceDimension in maya with Python. Maya will treat ['xxx'] and [u'xxx'] interchangeably. OpenMaya as om2 # Get the current selection of elements in the scene. This will give you the world co-ordinates of your selected vert pointPosition OBJECT. Here's an example that will simply mirror all points of a selected object along their z axis: import maya. error("No object or vertices selected") # Stores all vertices in a list if a mesh is selected vert_selection = cmds.
