My name is Tate Mosesian and I am a lead environment artist at Naughty Dog. I recently created an IMM brush tutorial for Z classroom on the Pixologic web site. The video series describes techniques I use at Naughty Dog for creating tiling textures for game environments. The 4r4 release has so many great new features added, but when I saw the IMM brush I knew exactly how I would be able to improve my technique for sculpting textures. The brick wall was obvious and easy to demo but the possibilities for this workflow are endless.
One of the reasons I’m starting this thread is to answer a question that keeps popping up: Why am I losing my polypaint colors when I drag out my insert brush?
I created the tutorial during a time when it was possible to preserve the polypaint colors in IMM brushes as they were being dragged out; however, in the short time between the creation of the tutorial and the release of 4r4 Pixologic slightly changed the functionality. You can still retain the polypaint colors its just a slightly different workflow.
Make sure colorize is selected from the polypaint tab in the tool menu. If you want to retain polypaint colors, turn RGB off. If you want to fill the brush with the currently selected color, turn RGB on. The same method applies to materials.
I hope this helps.
Here are some diffuse textures that were created for the Desert Village level in Uncharted 3 using the same workflow:
