Is there a way - could be using some script or plugin - to unwrap a model but keep the shells respecting the objet orientation?
as far as i know the addon textools has this function
Gonna check it out. Thanks!
Did you end up finding out if Textools has this function?
say for something like a wheel where you don't want say a light map on mapping channel 2 rotating with the wheel you can IIRC use a UVXform modifier with an expression controller for the rotation set to minus wheel rotation.
