I attached a filter which shows this problem. If you take two perlin noises with different angles and mix them in a pattern, the normal map will be weird and it looks wrong on a model.

I don't see anything wrong with the filter. However, it uses high-frequency noises, so the weirdness you're seeing might be caused by aliasing.
Try to render the normal map with Anti-Aliasing set to All Pixels, 65 samples per pixel, and see if the result looks better on a model. When exporting the normal map, use lossless compression if possible (PNG24 or similar) to rule out compression artifacts. |

Sorry, I missed your reply.
It´s not artifacts or antialiasing. It´s the lighting that is weird. One part of the map will always appear flat, like the left side on the example image. |

I have tested your filter and I get the same result as shown above, so it happens to me too, both parts look different
I suposse that what you want is to have BOTH having exactly the same look and does not look different as they are showing, so both parts are the same. |
