Displacement blotchy in shadow area

Displacement can be blotchy in shadow area

Hi @Smolak

That’s new. Can you send us this specific file? If not, you can try to isolate this portion.

Strange. This issue is gone when I go to material manager. All displacement materials with blotches are rendered fine. Problem is that if I not go to material manager before final render, these badly blotches are visible on final render too.

I tried to replicate it on my end using another custom displacement material, with True displacement enabled. Let me know if you can’t share the file.

I will try to isolate this. I think that this is related to amount of geometry in scene.

Another issue. After scene is growing displacement completely doesn’t work until I enter to material editing mode :
