Does this mean that colours are not part of the obj file but offered by a separate file? Sounds weird!

Can you offer a simple example, please?

I am also bumping into this missing feature on:
OS: Windows 7
Platform: 32-bit
Version: 0.13.1828
Python version: 2.6.2
Qt version: 4.5.2
Coin version: 3.1.0
SoQt version: 1.4.1
OCC version: 6.3.0


I uploaded (hope so) and example (blue-plastic-push-buttons.obj and .mtl). Place those 2 files in the same directory. Open the .obj file with GLC player and you should see a blue part.


Open this same .obj file with FreeCAD and you should see a gray part.
