You're in luck, However, I don't guarantee that it will be 100% up to date with the current version. I was also equally lucky that I was lazy enough to create a copy of the ETKC on my desktop to avoid navigating file structures all the time. It took me by surprise to find that after the recent update the materials.cs files were gone. Side question for any devs who may read this, do you have a special tool for converting the materials.cs files to json files?
