Ue4 4.7 Texture Issue
Ue4 4.7 Texture Issue1920×1080 181 KB

Hi! Does anyone know what these dark bands / stripes are caused by? I’m using Megascan textures, a height map from the marketplace and following an auto-landscape material tutorial by “Unreal Sensei” (Unreal Engine Landscape Master Material Tutorial - UE4 Tutorial - YouTube).

I’m quite new to UE4 so any help would be much appreciated :blush:

Many thanks!
