Hi there…

Sometimes importing a maya expoorted OBJ in another package gives me an error saying: “Different number of vertices and normals”...anyone knows what that means and if there is a way to fix it on the maya side? I thought that every vertice had a normal and i cant really understand how the numbers of vertices and normals can be differrent....Thanks alot.

I don’t think I’ve ever gotten that error, but from the way it sounds, it could be “Lamina Faces”.  Sometimes you’ll have two faces sharing all edges and all vertices, which could give you a double set of faces and a double set of normals.  Try selecting your model and click on “Mesh-Cleanup” and scroll down to the “Remove Geometry” section.  Click on “Lamina Faces”.  You might try “Faces with Zero Geometry Area” also. 

Be aware that this is a destructive process that cannot be reversed - you should make sure your file is backed up before you try it.

As I said, this is a guess - I’ve never had that problem before.

I looked up online for a solution to this problem, which I faced while importing the obj’s into Massive, but nothing.

Is there a workaround for this ? It seems like it is the objExport plugin in Maya which is not generating the right information as expected by Massive.

Any help would be appreciated.

Thank you.
