Short description of error
TIF files creates strange normal bumps
Exact steps for others to reproduce the error
- Create a plane and set material as a Principled Shader
- Use a TIF image as the normal map. The shading looks strange:
- Swap it with a JPG normal map and it looks fine
The same TIF file works correctly in Cycles, so I think it's isolated to Eevee.
8-bit TIFs work fine, just 16-bits are the problem. But since 16-bit TIFs are the industry standard for avoiding stepping in normal maps, this is fairly important.
