Hey there, thanks for checking out my Ko-fi page! I'm Dorian Zgraggen and I run cgbookcase.com. As you probably know, cgbookcase.com is a site with free PBR textures. All the textures are licensed as CC0, which means you can do pretty much anything with them. You can use them for commercial as well as non-commercial projects, you can publish & sell them as part of a 3d model on Turbosquid or you can share them with your friends. Plus, you don't even have to give credit. If you have a few bucks left, I'd highly appreciate it if you decide to buy me a coffee. :)
