Hi there guys. I'm 2 days into SP and I'm having a problem (of course haha). So, we're making a low poly game with very cubic sharp edge graphics (something similar to Grow Home, but more cubic) aaand I guess we need textures soo I had to try this awesome program and I found a way to paint only on the specific face I want and it's all good, but when adding more than 1 material I get this ->

Thanks for reading and I hope we can solve this one easily ^^
