as far as I know it's not possible.

Why don't you make a very thin cube??

Remember: one polygon is one polygon. You can't give two sides of polygon different materials. And this is what you're trying to do.

It is possible in VRay with a special material.
For Octane you would need to double you face and flip one to put your backside material on it. I don't have Cinema 4D but it is technical the same.

Remember that if polygons share the same 3d space you should see awfull effects in textures use a deformer to give thickness to your poly then assign your matérials to opposite faces.

Thanks all you are able to do this in c4d, using the back front option on the material tag without having to extrude or dupe the face. But it dosnt seem to be possible with octane. No probs, appreciate your time.

It is as simple as using a Mix material, placing both textures into the slots and putting into the Amount slot a "side" octane material.
