I am using my own library for distribution for the first time, I have populated it with over 50 trees and plants. But after building my first forest pack I notice I can't run Optimize materials. I have tried loading in an override material in the library but that doesn't help either. How do I apply this? I can't see how I can apply it in the library master file as there is not forest pack in there..
The main purpose of running the optimise is to get tint by element working, I realise I can re-apply scene materials to the forest pack but I am concerned that all my changes will get written off if the library re-writes it on open.
