Actually, it seems I have have spoken too hastily. I've still having
problems with making a python MPxParticleAttributeMapperNode - even if I
specify the mpx type when calling registerNode:
import maya.OpenMaya as om
import maya.OpenMayaMPx as mpx
class ParticleAttributeMapperNode(mpx.MPxParticleAttributeMapperNode):
id = om.MTypeId(0x870350)
def isAbstractClass(self):
return False
def initialize():
pass
def creator():
return mpx.asMPxPtr( ParticleAttributeMapperNode() )
def initializePlugin(mobject):
mplugin = mpx.MFnPlugin(mobject)
mplugin.registerNode( 'dummyParticleAttr',
ParticleAttributeMapperNode.id,
creator,
initialize,
mpx.MPxNode.kParticleAttributeMapperNode,
)
def uninitializePlugin(mobject):
mplugin = mpx.MFnPlugin(mobject)
mplugin.deregisterNode( ParticleAttributeMapperNode.id )
Then when I try to create a node, I get:
>>> import maya.cmds as cmds
>>> cmds.createNode('dummyParticleAttr')
# Warning: Node type 'TdependNode' is abstract. Cannot create. #
# Error: Failed to convert script pointer to c pointer: MPxNode * (converter
failed on type)
# # TypeError: Failed to convert script pointer to c pointer: MPxNode *
(converter failed on type)
# There is no such dependency node type: dummyParticleAttr.
I'm really stuck here. Any ideas? Is this just a maya bug? Things seem to
work fine when using a compiled MPxParticleAttributeMapperNode...
