I wish to use Blender to model level for 3D game. Level is a set of Meshes. I have to set special (additional) properties per face (triangle). These properties are like integer number or vector or color.

Ideally I would select a set of faces and set TAG1 to be 7 and TAG2 to be (1.0, 0.0, 0.0) and TAG3 to be Red for these faces.

• TAG1 is Integer
• TAG2 is Vector
• TAG2 is Color

Also I would like to be able to export that model in some format like Collada or OBJ. I use ASSIMP to convert model in my game internal format.

I believe OBJ does not support extra properties.

It sounds like very common task for gamedev. But I can't find any simple solution that does not require to create my own 3D editing tool.

Also I can consider using other 3D modelling tool if it has such functionality.
