Weird normal map problem

when trying to use normal maps on a spider lair base, on quest it makes it look diseased. any fix?

I could think of a few reasons – maybe the normals are (for some reason) on a different UV channel? Maybe the strength is too high?

It might help if you post screenshots of how it looks using Unity Standard vs, say, Standard Lite.

I have a similar issue, here is the full problems visible.

in game:

Issues are only prevalent in vrchat. strength is 1, albedo is all on Uv0;
uses logo loco. Issue started with the Vrchat unity sdk version update.
problem is not prevalent on PC.
