Hi, guys.
Was experimenting with getting displacement on the landscape. And since there is no support for tasselation displacement I’ve used Virtual HeightField.
Simple Beach Sand Material For Test. All works except I get weird flickering. Like switching between LODs while I am standing and not moving.
If I Have only Height RVT running its OK. But of course I want also draw RVT for color. And when I do it the flickering is happening.
Thanks for any hints in advance.
Cheers! 
There U can see exactly the same problem like I have. This ugly flickering !
Me too, haven’t been able to solve it so far. Have found some improvement by increasing the LOD distribution in the details panel of the RVT Height Mesh actor and/or reducing the size of the texture in the RVT material, but still get some flickering in certain situations. Try experimenting with the RVT Height mesh LOD settings when looking at a flickering spot in the editor.
same issue here, and LOD distribution doesn’t work for me. U can see the wireframe is changing without any viewport movement. acting as LOD changing or nanite-like effect.
I know this is an olde-thread, but I believe we stumbled upon the solution here, check your residency-settings to see if you are pooling-out: Runtime virtual texture sets landscape to lower mip - #59 by cannasoftware
