This pile of rubber pieces was located in an indoor gun range. This is a heavily detailed surface and couldn't be optimized too far without losing significant detail. This is an older scan before I started shooting RAW. It's 52 images and I think I was using a flash. I'm fairly happy with how it resolved all the depth of the geometry.
These photoscanned models have 8k maps for reasonable UVs, color, depth & normals. Enjoy!
