Iv been using Unwrap3D for a while, in fact the Mech in my demo was saved from Studio Max as a .x and then converted to .b3d using Unwrap3D. Brad is a good bloke, not all things converted at first but I sent him the model and he updated the plugin and now it works great. I think all Blitz users should have it, they should maybe offer a Blitz bundle like Darkbasic does with CharacterFX?
