I am currently dealing with a Blender to Maya to granny2 workflow using FBX as the exchange format between Blender and Maya. I know I should probably just move everything to Maya but that would take some ramping up time which I really do not have. So has anyone had success exporting custom properties out to FBX. Although the wiki claims its possible, I am not able to get these properties to appear as attributes in Maya. I know there is a dead tracker on this subject which I could re-submit but I would rather not bother the developer unless its a real issue. As a work around I have also toyed with exporting a relative shape key to act as the property container, again without success. Any thoughts or suggestions?
