Is there a way to save out a fresh version of your image file structure with out any images that are not current being used in the rig or better yet in any animations. I have a rig that I made with around 30 hands, 8 chests, etc and i have them used in the setup section of the rig but nicer ended up using some of the pieces in any of the animations. It would be nice to be able to figure out which ones are unused so i can save out a cleaner/slimmer final product.
I know i can go through and track down manually which ones are never used and delete them from the image folders myself... but in a large (older) project this can be very time consuming...
