A very peculiar, corrugated pattern appears on the baked normal map from the Bake from Multires option.
Everything I've done:
- 4k Resolution
- Non-Color Data
- 32-bit float
- Smooth shaded geometry before applying the Multires modifier.
No matter how I rearrange the UV, it's the same strange result. From top to bottom in the images is the high poly, low poly, the baked normal map, the low poly with the normal map applied, and the weird pattern moving along the topology.
