I am currently in the process of building a fairly large virtual environment, which involves 500+ buildings that have to be texture mapped and rendered.
This involves adding UV unwraps to all 500 buildings, and packing the UV's properly. I am using the Pack UV's tool in MAX (it's not prefect, but quicker than doing it by hand, and time is a factor). I still have to do each one manually though, which takes a lot of time.
What I really would like to find, is a script that automatically runs the Pack UV's tool for all selected objects, with a settings preset.
