Ola redcode,
EIAS dont have a UV automatic unwrap system, until now, doesn't exist a magical UV unwrap system in the 3d market (the closest one to magical is UV Master from Zbrush).
If you have a model with UV data, become easier, so, you need to bring it inside EIAS and add the texture, since its a UV coordinate, the texture fit automatically.
Sure, one of our goals is make 3d cross data easier to our user base, we are always researching.
Thanks
Tom
