These files are free to use for personal and commercial projects, so you can just grab them and start creating new scenes.
The author 3D scanned each piece and created a set of PBR textures.
The files feature:
- Base color
- Subsurface scattering (translucency)
- Displacement
- Roughness
- Normal maps
The creator note that there are two normal maps included: "one with micro details to use on top of the displacement and a second one with full detail to use on flat geometry."
All the free textures are 2k available in 16bit EXR format. You can learn more and get the files here.
