Hi, I am currently working on my open-world landscape, painting materials and stuff, but I have stumbled upon an issue that I couldn’t find anything similar to online. There is some random kind of blacked-out zone across the whole map. It shouldn’t be any type of shadow or anything like that.
The interesting thing is that when I edit the landscape, the affected component makes it disappear, which is even weirder.
This issue occurred after I reworked my material from HeightmapLayerBlend (which was kind of pointless since the textures are simple colors) to WeightBlend, which is definitely more suitable for my case.
So, has anyone got any idea what could be happening?
