Re: [Maya-Python] Can't access node name() in postConstructor of Node

[Dado Feigenblatt]

I needed to use postConstructor once and this was the only way I got it to work. The key part is to call postConstructor() on the base class. dado def postConstructor(self):         OpenMayaMPx.MPxTransform.postConstructor(self)         thisNode = self.thisMObject()         dagFn = OpenMaya.MFnDagNode(thisNode)         Richard Kazuo wrote: Thanks for the help Chad. Just to clarify, the docs also say this callback is obsolete and to use another method that when I click it, it takes me to the same deprecated one - this also happens in addNodeDirtyCallback. What should we use instead?

I tried getting it using the self.name() method inside the __init__ and that crashes Maya. I checked the MPxNode documentation and it says the node is not yet created in the constructor, so it makes sense. The docs say I should use the postConstructor method, but I tried it and it doesn't give me the name - I can only access it on the compute method. This is what I used to test: class testNode(OpenMayaMPx.MPxNode):     def __init__(self):         #print 'constructor>', self.name()  #this crashes Maya         OpenMayaMPx.MPxNode.__init__(self)         def postConstructor(self):         print 'post constructor>', self.name()         def compute(self,plug,dataBlock):         print 'compute>', self.name() Maya only prints out the node name in the compute section. Any thoughts on how I could get the node's name only once (outside the compute)? I can access self.typeName() though. Maybe I'm messing with something I shouldn't?
