I am currently having an issue where the specifically defined vertex normals I have on a rigged and weighted mesh are not being exported when I save out to an FBX file.
Attached is an image/example of my problem. Those meshes are being rendered in Unreal. However, if I export a rigged mesh in Maya to FBX, and then import it into Maya again, the same issue occurs. It appears that the normal information is not being exported out. I literally can not have user defined vertex normals if I export/import Maya's rigged FBXs into any other software.
Currently I have tested my FBX's in with:
Maya 2013 / FBX 2013.3
Max 2013 / FBX 2013.3
Quicktime FBX 2013.3
Unreal Engine November
Does anyone have any idea what might be going on? This is a huge issue in our current pipeline and essentially makes Maya unusable for modular rigged meshes.
