Free PBR texture websites

[sn0wsh00]

I thought I could share with you guys four free websites for physics-based rendering textures. All of these website allow you to freely download textures at any available resolution. They also do not require you to create an account.

AmbientCG

• Website: https://ambientcg.com/
• # of Textures as of September 2022: 1761
• Public Domain CC0 1.0 license
• Textures come as image files

cgbookcase.com

• Website: cgbookcase.com
• # of Textures as of September 2022: 535
• Public Domain CC0 1.0 license
• Textures come as image files.

Free PBR

• Website: https://freepbr.com/
• # of Textures as of September 2022: 434
• $9 fee to use textures commercially
• Textures comes as image files, but have been prepared for use in Blender, Unity and the Unreal Engine.

Poly Haven

• Website: https://polyhaven.com/
• # of Textures as of September 2022: 288
• Public Domain CC0 1.0 license
• Textures can be downloaded as a Blender file with shader nodes and lighting already set up. They can also be downloaded as a GLTF file or as image files.

It should be pretty easy to set up the shader nodes. Just connect base color/albedo/diffuse to Base Color, height/roughness to roughness, normal to normal and so forth. If you have an ambient occlusion texture, just combine that with your color texture using a MixRGB node.

And here's a comparison of similar textures from each website:

All of these balls were rendered in Cycles using the lighting that came with Poly Haven Blender files. If I had to choose, I would say Poly Haven textures look the best, in that they're a lot bumpier than textures from the other three websites. This might be because Poly Haven normal maps look like this, while the other normal maps look like this.
