World Partition - wrongly lit patches

[FFV-LM]

Hi there, I’m struggling with a weird glitch using world partition. It goes away if I open the landscape tool but is still there when running or rendering via MRQ.

Has anyone an idea what could cause that?

Thanks in advance!

Hello there @FFV-LM!

Since those patches dissapear when opening the landscape tool, yet remain on screen when rendering, it sounds like you are seeing HLOD proxies on screen, instead of the landscape itself. And if those HLODs were created before you made any changes to landscape or lights, then they will hold old data, resulting in the glitches you see.

To confirm this, use cmdlet r.HLOD 0, and check the screen. If the strange patches are gone, then it’s a HLOD issue, and to solve, you can just rebuild your HLODs by going to Build > Build HLODs. That will create new proxies for your land/light setup.

On the other hand, if the glitches remain in sight, I would test by rebuilding the landscape’s Nanite data:

For further tests, I would check the methods in the related thread below:

Distant Landscape Material Black when using World Partition HLODs

Hi, I was attempting to setup World Partition loading for my landscape, but I’ve ran into an error where distant HLODs render black in-game. I spent a few days searching forum posts and trying different settings to narrow down the problem, but I haven’t had much luck. It’s hard to find information on World Partitions, so some help solving this would really be appreciated. Here’s a comparison of what I can see in the editor, and when the game is running: [Screenshot 2024-10-03…
