Seamless 2K PBR wood pellet material with diffuse, normals, specular/glossiness 8-bit JPEG 2048x2048px maps. Displacement map in EXR 32-bit format.
In the scene, the sample application is an uneven plane with a Vray/Corona material set up with a UV tile size of 50x50cm.
Texture seamlessness allows you to fill the surface of any area (I recommend using it in conjunction with the Noise geometry modifier)

Displacement height ~1cm.
The system units are centimeters. All objects and textures are named.

*when importing from FBX it is necessary to set 'input gamma' = 1 to normal bump
*for better display of details we recommend Displacement Edge Length = 2px
