I've used it. Does a good job of getting the thing shifted around until it fits. How good it looks rather depends on the mesh. The results can be saved as an ordinary cr2 -- or exported as an obj, like any character. As far as conversion of mesh in carrara goes...I've done this too. There are a few tricks. Unfortunately, I just got off a twelve-hour work day and I'm not up for trying to describe them at moment.
