Custom Map Makers

Not sure if anyone has heard of this, and I know nothing about models so I have no idea if this can in any way convert to UrT. But here is a really intuitive modeling program called sculptris. It is free (with registration) and is in its 6 Alpha stage. I had it durring alpha 1 as well, and it has come a long way to being a stable, fun program. http://www.pixologic.com/sculptris/ enjoy, and if you can do anything nifty with it, post some screens!

Sculpting software seems to be gaining in popularity last few years.
It's definitely something that can be used to create impressive models, however without testing it i can't say of how much use would it be in UrT.
However sculpting adds thousands of tris in just one stroke so it can be used mostly to generate a high resolution normal map.
