[Maya] missing shading in several display layers

-Em'-

Here is the original post on reddit : https://www.reddit.com/r/Maya/comments/3vwswh/help_missing_shading_materials_on_several_layers/

I have a bug on maya, that makes objects under some of my display layers (not render layers, not using these) missing their shading.

This image shows 2 layers : one has a correct shading, the other is colored with the color of the layer. But they use the same materials (don't pay attention to the overlap, it's my collision mesh).

As i said on reddit, i use per-face materials : for example the road mesh is 3 materials. And as I have to manage multiple tracks, I need to have those display layers to hide I do not work on.

Any idea how I could fix this ? This is getting really annoying...

Have you tried switching to the legacy viewport shader instead of Viewport 2.0?

Just tried, meshes appear just hightlighted on wireframe... No texture, no shading.

Try right click the layer and choose remove mat override?

When i do so, the meshes just turn unlit green. Same happens if I remove objects from the layer.

IMO it's not worth trying to fix it. I'd just delete that layer and recreate it.

Hum, so i tried working without layers, but bug still here on newer mesh that were never assigned to a layer...

Green missing materials, for no reasons...

Any idea ?

Edit : i found  this thread http://forums.autodesk.com/t5/forums/forumtopicprintpage/board-id/area-b201/message-id/28571/print-single-message/false/page/1 and it describes my bug... But can't find any real fix, even if they suggest workaround this is silly and workbreaking... And what is even mroe silly is that I had this same bug with triangulation in maya several month ago, that was reverting my UV's when exporting to fbx.
