This is my " Desert " location. Nothing almost there. Epic games default material, something from …sand… series. Landscape made with engine tool. This work with heat up 70-80 degrees. Just sky. No any tick related options. But location really large, have 3 " city imitation "(I remove much parts of those actors).
I suspend landscape eat many resources… May be I will make it land in Blender with simple.
Location Ocean have 3 islands with trees and grass. this most loaded with meshes in game.
may be I do stream leveling, in 5 version I hear removed, but this 4.27. stream leveling not easy to customize…
