I may have missed something, but I do not seem able to map a decal (or material pattern) in a consistent way across multiple faces. I would like to be able to do this for my following project. There are a number of situations where this ability would be desirable.
Currently, the material pattern / decal is confined to indivdual faces. At the moment, I have compromised by tiling the pattern, but it's not really the effect I wanted.
