Hello,

I have some issues with Maya FBX export.

If I have two nodes in the scene with different materials, but those material share common nodes, some of the content will be dropped in the resulting FBX.

As an example, if I make obj1 with Material1 and obj2 with Material2, and both Material1 and Material2 uses a layeredTexture as diffuse color, in the resulting FBX only one material will have the link to the layeredTexture.
This forces us to duplicate hypershade tree for every material instead of sharing common nodes.

Please let me know if you can’t reproduce, I can try to generate a simple Maya file that exhibit the issue.

Thanks!

Thanks for the reply.

I currently use 2013.1 (had the issue with 2012.x but waited for 2013.1 before reporting it, in case it was already fixed).

I attached a file exhibiting the issue (with generated fbx output).

In the Maya scene, Outdoor and Outdoor_2 both have DiffuseColor pointing to layeredTexture3 (which points to 3 textures).
When you export (in my example I exported pCube1 and pCube2), inside the resulting FBX file, Outdoor points to layeredTexture3 as expected, but Outdoor_2 points to one of the subtexture of layeredTexture3 instead of layeredTexture3 itself.

Please feel free to ask if you need more info!
