This is, simply put, an aesthetic mod. It changes the look of all the the clones (except the Jet Trooper) to that of the ARC trooper. Their colors have been changed accordingly, as well. The Jet Trooper is the only unit left untouched, this was due to technical restrictions.
Download the folder and follow the ReadMe file. If you have any problems installing or uninstalling the mod, let me know, and I'll do the best I can to help.
