I would imagine it would be pretty simple to subdivide a texture atlas material into parts in the material editor such that it would tile just those parts over selected faces while maintaining a single material for the model. There's really no way to do that?

**I'm trying to export my SU models into a game so that I can make a custom city. The problem is that the game requires a single diffuse texture for each entire model.

Is there a way to automatically combine the SU materials before export such that they UV map to one combined texture file instead of a bunch of them?

Thanks!**
