Lightmass and Load level instance crash on VR(Android)

[Nizami_Nz]

Hi all.
The problem is that when I try to dynamically unload a map with baked lighting, the client (VR Android) crashes.
But the server is fine.

At the same time, once, the game still allows you to load the map from the client, but when you try to unload the map, it crashes again.

I know absolutely nothing about multi, but it looks to me like you have streaming and instancing a bit jumbled up here.

As far as I understand it, having dormant sublevels like this is for ‘load streaming level’. You can use ‘load level instance’ without it

Long shot, but perhaps that’s confusing the system?

Hi, thanks for the reply.

I tried to remove all levels and just use (‘load level instance’), but the result is the same, everything is fine with the server, but VR (Android) crashes, even in a scene where there is just a baked cube.

I’m using (UE5.2)

Ok, sorry, worth a shot… :-/

The problem was that on the main map, to which the other maps were connected, there were (Sphere reflection capture), as soon as I removed them and moved them inside each submap separately, the crashes stopped.

• I also reduced the resolution of the baked map (Compress lightmass = 1024)
• Set all textures to maximum resolution at 512
• Reduced the resolution of baked reflections to 128
• Also try to delete, into main map a file for the baked lightmass.

In general, I think that such errors are almost always related to the main map.
