Looking for free and awesome looking high resolution PBR materials? Well, CC0 Textures is an excellent place to start looking 😀
Physically Based Rendering allows for incredibly realistic surfaces, but generating a good PBR texture ain’t easy: You need to wait for good lighting conditions, go outside and shoot the textures, stitch the images together to get one high-res image, make that seamless and then generate all the maps. This process does not only require equipment and software that not everyone has, it can also take quite a while.
That’s why most people usually rely on sites like Textures.com or Poliigon.com to get all the surfaces they need. And that works great if you are willing to spend some money or live with the free low-res versions on Textures.com. It does not work however, if you wish to distribute your work in any other way than just a render! Reselling textures from Poliigon or Textures.com on sites such as the Blender Market is a slippery slope to say the least.
That’s why that site exists, all textures and maps are licensed under the Creative Commons CC0 License, which allows you to do pretty much whatever you like with these images. Use them in your renders (even commercially!) or bundle them with your models! If you have ever heard of HDRI Haven – It’s basically that, but for PBR textures!
