Vastextures
Full name: Vast Dataset for textures and PBR materials

VasTexture is a free giant repository of textures and  PBR materials extracted from real-world images. The repository contains 500,000  highly diverse textures and PBR materials. All assets are free to download and use.
The PBR materials and textures were extracted from natural images using an unsupervised approach (no human intervention).  As a result, the textures and PBR materials are significantly more diverse but also significantly less refined compared to assets made using manual and AI approaches.
