Currently, Maya2egg doesn’t export UV coordinates if there are no texture attached to them. Is there way to force it export it? Also, when a maya file has multiple UV sets, it doesn’t export the additional sets unless a texture is attached to them. Can we make a flag to force this to happen?
I believe if you add the flag “keep-all-uvsets” to the available flags in eggObjectFlags.mel, and then apply this flag to a node in Maya, then maya2egg will convert all of the uvsets it finds on that node and all of its children, regardless of textures.
