Different materials on each side of a cubus

Development Getting Started & Setup

I’m an absolute beginner with Twinmotion.

My problem is how to place on the different surfaces of a cubus different materials?

I have imported this cubus as a .dae file which was created from AutoCAD AEC geometry.
Same done with 3D ACIS Body.

After import i always get one object.

(My real usecase is a wall. On this i will place different materials on outer/inner side. At last on the thickness of the wall which is in some case visible.)

How to import?
Can i manage this directly within Twinmotion?

Your source model should have different material (even without bitmaps) then you could replace them in TM. There is no option to apply to a material to one (or a group) of face in TM
