Old baseball, 3D-scanned. 3 models (low/medium/high quality) plus ZBrush source file with cleaned (retopologized to quads) 20 million polygon version of the model.
Also included are color texture, displacement map, normal map, specular map, and the Maya file I used to render the sample images. Redshift is the render engine I used.
All textures are 8192x8192.
