Our goal is to create a constantly growing community-funded resource of open content, licensed as CC0 for complete freedom and usability by professionals and hobbyists alike.
All models there are CC0 (public domain and copyright-free). No paywalls, accounts or email spam. Just download what you want, and use it however you like.
We received a $10k grant from Epic Games to get the ball rolling, but from this point forward everything is 100% funded by our community on Patreon. If you want to help us keep producing assets, consider supporting us there :)
Most of (and soon all) the assets used in the image above are available on the platform. If you're curious how the render was made, here's the thread on BlenderArtists.
