Cannot apply multiple materials to one object

[tibique]

Hello,

 

This is my first post on this forum. I am trying out cinema 4D and I have the following problem with materias. When I have an object I cannot apply more than one material to it. Even if I select the triangles / rectangles, one material always covers the whole object. Like when I have a window which is made of glass and wood, when I apply wood the the frame it also covers the glass. I use arion render for rendering and apply fryrender materials. I tried to use layers as in the tutorial I have found on the internet, but I have just one layer for all, my objects (buildings) are imported from chief architect as 3ds.

 

Thanks for your help.
