Maya: Creating Arnold shading nodes by script
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");
