I just started using Sprytile and I'm absolutely loving it so far, definitely a powerful tool. I have constructed a mesh to use as a ground, and I wanted to go in and paint my grass texture onto the faces, however when I attempt to setup pixel texture on any mesh I have already created, without starting to build from Sprytile, I get an traceback error message. I'm not super versed in technical terminology as I come from an art background, so I'm not sure what the problem is exactly, but I'd like to know if this is a hiccup you are aware of? It works completely fine when creating a separate mesh within the edit mode of an object I had begun with sprytile, but I keep running into this error when attempting to paint meshes I had already built. Any suggestions or advice would be greatly appreciated! Thanks so much for putting this amazing tool out there.
