I own Ultimate Unwrap. But having to export C4D file with animation into a different format that supports animation kind of defeats the whole idea when XPort can do the same thing. The problem with Xport is it can't handle the new Cinema 4D R10+ character riging scheme (joints + weight maps) you have to use bones and absolute vertex weight maps (theres no easy way to convert these as it can screw up the skeleton and you have to weigh the vertices to each bone).
