I’m also struggling with this topic.
I’m trying to create some displacement for the terrain in UE5. This method although much harder to setup than previous tessellation option, seems to be working OK. In terms of performance it is much better than what tess could offer.
The problem I’m facing though is incredibly sluggish update of the VT.
It seems like it doesn’t have enough memory to stream properly. Tiles are popping very noticeably and often are blurry for seconds before clear. Sometime they even get stuck and never clear.
This is not to mention the mesh popping and flickering of the Heightfield mesh itself.
The proposed solutions above , don’t work for me. And I really cant see how they could , one will just disable the mesh itself.
Wondering how do we correct for this. Is there someone with some experience with RVT on landscapes to recommend some settings - on the VT texture , console commands etc.
