Hello,
I'm developing an open source 3D texturing application named CrackArt. I've been working on it for a few years and I consider that it's ready to create textures using the RayTracer tools.
This video tutorial shows how to transfer textures from a high resolution model to a low resolution model using the Texture Baking tool and the UV Atlas modifier to generate an optimal, unique texture mapping mesh.

I'd like to invite you to test it and to send me suggestions to improve it. CrackArt can import scenes using the FBX and 3DS file formats, and it includes import and export plugins for 3dsmax and Maya.
