Hello Everyone,

I’m trying to use the animation sample project from unreal for learning purpose.

I did create level open world template map using world partition of 4033x4033.

But seems that the landscape streaming proxy actors stoped working when enabling the new camrea system (DDCVar.NewGameplayCameraSystem.Enable, camera rigs), because only the central area of the map is correctly rendered (HLODs also built), otherwise the character fall from landscape.

If you put a playstart in other areas of the map or if walk outside central area, the charactar fall from landscape, and you can see the area is not redenred properly and the actors is not loading the areas anymore.

My Game Mode Setup:

Here’s a streamlined guide to troubleshoot the issue:

1. Check World Partition Settings

  • Ensure grid and cell size are correct to load the needed areas.

2. Validate HLOD Configuration

  • Confirm HLODs are properly generated and configured.

3. Camera System Conflict

  • Disable the new camera system (DDCVar.NewGameplayCameraSystem.Enable = false) to check if it’s causing the streaming issue.

4. Verify Streaming Proxy Settings

  • Ensure LandscapeStreamingProxy actors are correctly set up and align with World Partition.

5. Character Falling Issue

  • Check if streaming settings and Level Streaming Distance are suitable for your map size.

6. Review Logs

  • Check the output log for warnings or errors related to streaming.

7. Rebuild Streaming Data

  • Rebuild your level’s streaming data and HLODs.

8. Test in a Simplified Map

  • Create a smaller map to see if the issue persists.

Try these steps to identify if the problem is with the camera system, World Partition, or streaming configuration.

I did test the Item 3, and the issue not happens, but the new camera system doesn’t apply (the new flow is only when is true).

With false, the streaming and hlods are good, i’ll check the others steps.

Thanks a lot.

i Tried something here:

I added the world paratition source component in the player controller class and the streaming started working again, however i have two sources now of the world partition:

The PC_Sandbox0 is the default (not working) isn’t moving or making the actors load.
The PC_Sandbox_0_0 is the second one that i added (worked)

Seems the new camera system is affecting the default streaming partition source in player controller:

The camera control is with the camera rig:

What i did, i disabled the default streaming source on player controller and add a new one like before:

Worked, but i don’t why the default streaming source on player controller is being disabled when change the camera control to the camera rig.

I found another issue, when adding the world parition streaming source, some proxy didn’t load right.

I disabled the streaming in the player controller and add the world partition streaming source in Character Blue Print, solve the issue for now, but to be honest i don’t know what happened when using the new camera system. I’ll close the question.

Thanks a lot.
