Hi!

I have an object that requires a layered texture. The first layer is the base diffuse map and will be assigned to UVMap1 the second layer is dirt and grime diffuse map assigned to UVMap2. The different UVSets help me isolate what aspects of the model are clean and dirty as well as enhance highly visible area’s.

To achieve this in Maya I would use Layered Texture, assign both my maps, adjust the blending, then use the relationship editor to setup UV-centric UV linking. Maya correctly displayed the results, however when I expect to FBX both material maps are suddenly linked to UVMap1.

I am currently using the Quicktime Plug-in to view the FBX file, and I suspect that using the relationship editor is causing the problem.

Is this possible with FBX? If so is there a better way to handle this?

Using Maya 2012 x64 with FBX 2012.2

Hello Avotas!

The problem is not with the plug-in, but with the tools you are using to display the results.  What I mean by that is, FBX for Quicktime cannot display objects with multiple UV sets.  As a side note, FBX for QT uses the same kernel as Motionbuilder, so Motionbuilder would not be able to display the object either. 

The plug-in does export multiple uv sets correctly though.  Exporting and re-importing into Maya will display the object correctly, which shows the fbx file keeps the correct information.

Cheers!
Carlos

Thank you!

That also explains why my normals are being displayed incorrectly. Sense the QT plugin uses the same kernel as MotionBuilder, and MotionBuilder has that issue requiring split-per-vertex to be enabled, it makes sense for the QT plug-in to exhibit the same limitations.
