I created a plug-in to displace the mesh based off a 2D texture and a membership. Suppose not looping through vertices that will stay at their default locations is worth the extra computations.

You actually shouldn't get the mesh object this way as it will cause an extra evaluation of the upstream dependency graph nodes. If you need the mesh object, you should override the compute method instead. If you look in the documentation for MPxDeformerNode, it gives an example of how to do it.

perfect! this did the trick!
thanx brian!
i was trying too hard to get something with using
OpenMayaMPx.cvar.MPxDeformerNode_outputGeom i think! ;)
