Multiple materials broken in FBX Importer of Blender 2.73

Blender Version
Broken: 2.73
Worked: 2.71

If i import FBX from UE4 where this FBX has multiple materials assigned, then in Blender 2.73 if i select one Material and just switch "Shadeless" option in Blender Material tab to see which part of imported model is assigned to this material, in Blender 2.73 whole model is shining which is bad.

In Blender 2.71 shines only the correct parts of model. Material is correctly assigned.

Exact steps for others to reproduce the error

  • Import FBX file (FBX 2014.2.1) with multiple materials assigned. Every material assigned to different part of model. I exported this from UE4.
  • After import to Blender, the model, or to be clear, the materials are imported wrong. Instead of being correctly linked to specific parts model, the first material covers all model, so the model is broken if i want to later export the FBX back to game engine.
  • To test this bug, after import of FBX, select first material in Material tabs in Blender, and toggle Shadeless property. You will see whole model is shining and not just the part which is correct, as in older Blender.

Blender 2.72 seems to be good too, although i dont see the imported skeleton / armature in this version as in 2.73 (if i am not wrong)

Also, please specify exact Blender version you are using (I made some changes a few days ago, which had some issues, just committed a fix).

Hi Bastien, thanks for reply.

Yes I am going to attach now, i was was thinking i should do that :).

I downloaded it here i guess it is the version currently there blender-2.73-8a28895-win32 (Windows 32 bit).

In Blender top bar i see 2.73.1 (in about Splash i see hash 8a28895).

Thanks for your cool work! :)
