Nanite Tessellated Landscapes seem broken in 5.6 on 4K Resolution In 1080p desktop res it looks fine. And also in builds in 4K it has the same flickering problem. I also know Nanite + WPO is broken in 5.4+ ( already submitted a bug report a few months back) in both 1080p and 4K desktop resolution. Is this a well known bug ? NOTE : Not sure if it matters but I’m also using assets from the ElectricDreams demo so Substrate is also on. I also tried Substrate off and the ue-main branch/UE5.6 and it has the same problems. I’m also using an RX 7900 XT. ---

Up! I have the same exact problem on Skeletal Meshes with nanite displacement. ---

Tested in 5.7.1 with a different project and I’m surprised it also happens on non-landscapes.

574 it works for me but only in the editor. Play-as-standalone, I got nothin’. Been that way for me since I stepped onto 57x; I skipped 56. ---

So “works for me” means you ran it in 4K resolution and it doesn’t have the artifacts that I showed ? ---

What I mean is: - 4k desktop resolution - when I play in editor, it’s obviously less than that given the window-in-the-app, but tessellation works (shadows in the lee of the rocks on the ground): - when I use ‘New Editor Window’, fullscreen 4k, tessellation works: - when I use ‘Standalone’, fullscreen 4k, tessellation breaks: in 58 it seems to function again. ---

I don’t see flickering holes in your screenshots though. And you’re not putting the camera close to the ground either. You need to be at like 10cm close to a surface, then even far surfaces will flicker. ---

For what it’s worth, I can’t reproduce this in 5.8 using screen percentage to force it to 4K or higher. I’m on Linux/Vulkan with an Nvidia GPU. ---
