I had the Problem, that when i add new layers or change the landscape material, at first it is shown black. To get the Textures work, you have to “rebuild” the landscape tile which turned black or has black spots.
I assume this has something to do with nanite landscape. I hope this works for you guys too!
I had the same issue in 5.1. I eventually got it working by going to the paint tab and changing the Base material from ‘None’ to ‘Base_LayerInfo’.
Hello Akio, thanks for sharing. The issue we had was about the 5.3 version bug and now it solved.
If you have this problem, go to landscape Nanite and rebuild data, in my case this happens with multiple layers, and I solve only running rebuild data, in my case on landscape Nanite is enabled.
This is it! A ready and quick solution. Tnx bro!
The “fill layer” for the automaterial at the end after created the layers fixed the problem. Thank you!
