Photogrammetry model of an unshelled walnut.

The model has three base levels of detail, optimized into uniform triangles with clean UVs.

Lod 1 = 32,000 tris, Lod 2 = 2,000 tris, Lod 3 = 500 tris.

The model has 4K PNG textures (Albedo, Normal, Ambient Occlusion, Roughness and Gloss). All levels of detail share the same textures except for the Normal, where each LOD has a unique Normal map.

Lod 2 used for 3D preview with 1K JPG textures.
