Zero Brush by Blender Sensei helps you to quickly set up materials for texture painting.
This is an addon for the opensource software Blender. This addon allows you to paint instantly in Blender without any prior knowledge about materials, textures, uv maps or the proper settings required to get started. In addition, Zero Brush also unifies the various modes of Blender which use brushes such as sculpting and particle edit (hair). It actually does a lot more than that but you'll have to see it for yourself. For instructions on installing this addon as well as using Blender in general visit youtube.com/blendersensei To visit the official wiki go here: http://blendersensei.com/zero-brush/
NOTE: Integration for Cycles should be out around the first of August.
