I had a nice discussion with my rigger friend and found out neat way of setting up rotation controllers with less offset nodes. ;p Sample code A: def sample():     import maya.cmds as mc;     # Regacy using an offset node     c01= mc.circle(n="RotateA_regacy")[0];     c02= mc.circle(n="RotateB_regacy")[0];     os01= mc.ls(mc.parent(mc.group(em=1,n="offset"),c01),sl=1,l=1)[0];     c02= mc.ls(mc.parent(c02,os01),sl=1,l=1);     mc.setAttr(os01+".rx",90);          # Tips using jointOrient and changing shape's parent     c03= mc.circle(n="RotateA")[0];     c04= mc.ls(mc.joint(n="RotateB"),sl=1,l=1)[0];     nc= mc.circle();     mc.parent(mc.listRelatives(nc,ad=0)[0],c04,s=1,r=1);     mc.reorder((mc.listRelatives(c03,ad=0)[0]),back=1);     mc.setAttr(c04+".jointOrientX",90);     mc.setAttr(c04+".drawStyle",2);     mc.dele...

I created a GUI to set wireframe color of selected nurbs curves. Primary commands, attributes and others used: - setAttr(shapeNode+".overrideEnabled",1); - setAttr( shapeN ode+".overrideColor",colorIndex); Prerequisites: i3d.pyc, i3d_main.pyc, i3d_utility.pyc, i3d_rig.pyc pyc file location(Google Drive): - i3d.pyc https://drive.google.com/drive/u/0/folders/1YcdLQ4s-0sCT_l9rMWBmbefXKSlVAQX8 - the rest https://drive.google.com/drive/u/3/folders/18u9JizS2Fr12XF2ZH6QmKbga59p1c_Xn

I've been Maya artist for quite a long time and started to learn how to get infos I need for the i3d tools in Blender. I will try to leave a note for those Maya script artists learning python scripting in Blender 2.8x. ;) def gettingSelectedPolyVertsInMayaFormat(): import bpy; selectedVerts= []; mode = bpy.context.active_object.mode; # Getting current mode bpy.ops.object.mode_set(mode='OBJECT'); # Setting object mode to get selected objects objs= bpy.context.selected_objects # Current selected objects for obj in objs: # Finding selected vertices of the selected  if obj.type=="MESH": # if the object is polygon..   verts= obj.data.vertices; # get all poly verts of the poly object num= len(verts);  for i in range(0,num):   if verts[i].select: # if the vtx is selected..   mayaVTX= obj.name+".vtx["+str(i)+"]"; # Getting selected vtx in Maya format selectedVerts.append(mayaVTX);   bpy.ops.object.mode_set...

Setting a video file to a new camera import maya.cmds as mc; # Creating a new default camera cam= mc.camera(); # Transform node of the camera cam_transform= cam[0]; # Camera shape node cam_shape= cam[1]; # Camera shape imagePlane attribute image_plane_attr= cam_shape+".imagePlane"; # A video file my_video_file= "my_video_file.avi"; # Applying a video file to camera's image plane attribute image_plane_nodes= mc.imagePlane(image_plane_attr,fn=my_video_file); # Transform node of image plane image_plane_transform= image_plane_nodes[0]; # Image plan shape node image_plane_shape= image_plane_nodes[1]; # Setting image plane type attribute to "movie" mc.setAttr(image_plane_shape+".type",2); To my knowledge, it ends up with  disabled  Image Number. (No expression is generated) So, I studied through echoed all commands and decided to use MEL command. - import maya.cmds as mc; # Create an imagePla...

Placing buttons to an image I am creating some tools for animators and in need of refreshing my old memories of coding "buttons to an image" using python. I created a sample python code file, so that I would not need to dig my old library of scripting tools to get sample codes. :p Download and place these 2 files to your script folder. Python script file: i3d_sample2.py Sample image file: i3d_sample2.png Python command: import i3d_sample2 as sample2;sample2.buttonToImageGUI().main("sample2"); This is how it looks. *Reference commands:  columnLayout,  formLayout, button

When creating Arnold shading nodes by script, use shadingNode command instead of createNode command. (Maya2018) # shadingNode command cmds.shadingNode('aiStandardSurface',asShader=True,n="arnoldNode1"); # createNode command # This node will not be visible in Hypershade window. cmds.createNode('aiStandardSurface',n="arnoldNode2");
