I wanted to bring up this awesome tech that Disney put out. Ptex is a system that allows you to texture models without the need for UV's. In a production, a texture artist can start working on actually texturing their models without the previous dependency of creating UV's first. Disney began developing this years ago and were able to first implement it in the movie Bolt. It's a really nice way to work especially because in the past, you would need to blindly UV your models and kinda guess which areas should get more UV real-estate. Now you can texture your model first and make informed decisions when UV'ing your model later on in the pipe.
Why not just skip UV's altogether? Well not all systems support Ptex. We have Autodesk and SideEfx supporting this tech as well as the various in house tools that Disney and Pixar work with at the moment. Currently the tech is spreading out and will probably be supported by game engines and other renderers soon. Disney did a decent job documenting the progression of this project here.
Hit the jump to see the latest video demonstration of Ptex using Mudbox.
I'm going to try using Ptex in my current modeling project to see how it works out.
