Tessellation not working in Standalone (only PIE)

I can not see tessellation in my landscape anymore when playing in standalone (UE 5.7). If I play in a new editor window (PIE) everything is fine.

For nanite meshes tessellation is working fine in standalone, but the landscape remains flat.

It was working once, suddenly stopped. I rebuilt everything multiple times.

I even created a new project with a simple landscape and material, still the same. Tessellation in PIE works, but in Standalone (via Editor) there is no Tessellation.

I thought I was going crazy… I have the same issue. Works fine in editor, in PIE, but not standalone..

I too rebuilt my level from scratch in 5.7 but no relief.

WTH Epic???

Same issue in 571..

Same issue in 5.7.1 ! Maybe there is something to build?

This is related, but I use temporal-sampling for triplanar/layer-blending, and it seems to also be borked in standalone vs pie:

I experienced the same issue, and it seems to be an engine bug. I resolved it by modifying the engine. You just need to change ULandscapeTextureHash::IsEditorOnly() true to false, save the level again, and then load it. I will need to test the stability further, though. So far, there haven’t been any major issues.
