Mapping question

unhandled

#1

In the attached file I have applied a picture material to the inside surface of the ring. I would like to apply a different picture material to each of the end surfaces. I can’t quite figure out how to put a map channel on those 2 surfaces.

Turns out I was able to use a decal to solve this problem. Is this the only approach?
