as I was annoyed with having to recreate stuff at work, which I already did at home, I changed my website so I can upload Unreal Material Networks. Maybe this will benefit to other people as well. If you find something you want, you can just copy the material network with one click and paste it in Unreal.
Unfortunately it’s super unoptimised and takes ages to load (because of all the gifs), so be careful on your phone. Need to find a better solution for this…
Also if you yourself have useful material tricks, just PM me and I’ll add them. Some of the stuff is already just recreated from other peoples posts on twitter, if that’s the case I always try to credit the author.
