Hi @dalikdik, there are 2 things attracting my attention
-
In the first scene screenshot, isn’t the landscape looking shiny as well? At least, it looks to me as if there are strong reflections on the right side of the image on the ground.
-
The normal map input at least looks somewhat strange to me at a first glance with that red color.
Could you please just try to remove the normal map just to verify, that your problems are not caused by some weird normal map trouble, possibly caused by bad (import) settings etc…
You could even replace base color by simple color value to make any artifacts better visible and drill down to the very minimum setup for debugging.
Just some ideas…
