A simple tool to apply multiple model material import settings

** I've posted an update to this script in a new thread! View it Here! **

This tool allows you to search and remap multiple models in the project view at one time.
To use it, select 'Caustic/Change Material Import Settings'.
Setup a model the way you want and press 'Copy Settings!'.
Select other models and press 'Apply Settings'.
Editor Window, place it in your 'Scripts/Editor' folder.
If it was helpful, I also make other games and software. Contributions will go to my next in-the-works Stealth/Action title.
