Hey guys,

I've developed my own robot model using Autodesk Inventor. I have added some color to the robot model. I convert them as follows:

Step -> VRML -> DAE.

When I import the VRML file in BLENDER, I lose color. Is there anyone, who have faced the same problem? Or am I doing something wrong?

Blender allows to export materials in collada (DAE) files. Can you specify which Blender version you are using? Could you share an example part (*.blend file with us?). What do you mean by loose color, does it become black, grey?

Thanks for the response.

Yes, it turns into grey, when I import the VRML files into the BLENDER. When I open the same VRML file in FREECAD, the colors remain intact.

So the color is lost when opening the VRML file, not when exporting to collada?

Yes! Exactly! I have updated the question!

@VictorLamoine do you have any idea?

With FreeCAD, export to PLY, OBJ (they are multiple exporters for the same format), these format retain colors, then import with Blender. Is it per object coloring, per face coloring, UV mapping textures?

Per object coloring !

The colors have been pre-added in autodesk inventor
