UVW Unwrap Modifier problem after import into 3DS Max

Thanks for the speedy reply! I think this may work. I have my separate meshes now, however I am unfamiliar with _Weld. After I’ve selected the meshes I want welded, and set an angle tolerance, should I get some sort of confirmation? I’ve tried angles from 15 to 90, however they stay separated. Maybe I don’t understand the _Weld command, but is it supposed to join coincident vertices? And how do I know that its been successful? And should I join everything together after welding?

Thanks!
