Morning All,
This is merely a continuation of the same problem set. I have/had implemented what was suggested by Bronwen and it works perfectly in 2008->2011.
There seems to be some internal changes for 2012-> for MPxTransforms because the exact same code immediately crashes.
I am attaching a stripped down version that throws the same error. It is when using the inheritAttributes function on a node within the internal heirarchy. IN this case a super class and one subclass.
If you switch the type out to MPxNode it is the same result, which is why I am more apt to think it is the way in which I am doing something, and not the specific Maya node type I am attempting to override.
As always, if anyone can spot anything fubar with the code, I really appreciate the look.
The solution is VS2010, but the code is all straight up C++, with the plugin.def providing the plugin exports.
