After upgrading to 2015 I have a number of custom transform nodes that crash Maya upon undoing a move command that were working as expected in 2014. Has something changed in the API or the requirements for implementing MPxTransformationMatrix?
I can reproduce the crash by using the rockingTransformCheck node in the dotnet examples project. Compile, load the plugin, run the mel script, select the rockingTransformCheckCSharp1 node, move it, undo, crash. 100% reproducible on my system.
Please advise and thanks in advance!
