Hello everyone.
i got a problem everytime i try to edit 2 normal maps togther in photoshop.
after i export my final normal map and view it in substance it shows with alot of artifacts and kinda pixilated
tried to export it with huge scale same problem
i also tried to disable sRGB in export settings also same problem.

the fix is to not bake with averaged normals, set up your hard edges/UV splits properly and you won't get the skewing
but what i mean is that i combine 2 normal map layers
1st layer is the normal map baked with average normals
2nd layer is baked without average normals
to get the final normal map which i am using in the first (Model)picture
What you have after this process is a normal map that doesn't work with your mesh regardless of whether you use averaged normals or not .
Bad practice aside though..
I don't think thats necessarily the root of the artefacts in your original image - there's a better than zero chance that Photoshop is applying some sort of color transform to the image on import and/or export. If you completely disable color management it should (in theory) not destroy your image
As soon as you start painting or masking or blending, you’re breaking that baked connection between the map and the vertices. Which means you’re likely to see shading problems.
You can usually paint out small errors without much risk, but it’s a bad workflow that makes the process slower over time in actual production.
If it's the case you have a number of tools to work with vertex normals: copy /paste , project from other geometry, clever use of split /hard edges, support edges, face weighted normals etc. It's a bad practice to fix shading artifacts by a normal map.
