im having an issue with world partition cells not unloading properly for me. i tried as many tricks up my sleeve as i can with no success. the problem also persists across multiple new projects and configurations. problem: when having a world partition with multiple cells, flying away from the land…

made a quick little recording as demonstration of the system working as intended in 5.1 preview. [unreal engine 5 world partition debug in 5.1 preview] the landscape chunks get loaded properly when in range (green cells) and unloaded but remain in memory (purple cells) and finally full…

No I have the same problem. New Landscape 1x1km, 8x8 comp / proxies [image] And here a 8x8km map from far away [image] a little closer [image] and little closer [image]

Hm, couldnt edit my post. Forgot this test map. Its 40x50km [image]

I have a similar problem…some of my landscape-tiles remove themselves when pressing play and won’t load in when i am near them. But in Editor, i see can see everything. [grafik]

Got it, I’ll post here if I find anything.

@Sebastian_OK you’re 40x50km screenshot is interresting. it reveals that once you go with a massive enaugh tiled landscape, it’s no longer just a + sign pattern of cells that refuse to unload, but rather an entire grid pattern of cells that refuse to stream out.

Same issue here as well. Just missing chunks lol

That’s no ordinary “grid pattern”. That’s a quadtree. Those are used to speed up certain kinds of operations (e.g. finding the nearest neighbor of something). They’re probably using them to speed up finding the tiles within range. What’s interesting is that the tiles within each cell of the tree ge…
