Unloaded Landscape

Sorry for being a newbie. I saved and closed my project last night and I am trying to work on it again today, but when I enter my level it just shows the lighting and nothing else. The Outliner shows everything unloaded. When I press play it all loads in and I can see the landscape and assets.

Thank you

Hey there @TechnoFilms! Welcome to the community! No need to apologize, everyone starts somewhere and we’re all learning something new every day! So it sounds like your world has world partition enabled and everything is currently unloaded.

So your scene probably looks like this, with all the things in your outliner showing as (unloaded). You’ll need to navigate to the world partition tab, select all of your tiles, then right click and click “Load selected cells”. You should be able to see everything is unloaded!

If your world partition tab isn’t open, you can open it from window->world partition the top.

The reason the level remains unloaded is so you can open larger scenes quickly and only show what you need to work on at a time.

Let me know how it goes!

I’m having an issue where my proxies are loaded but my landscape is unloaded and I cen’t edit the landscape anymore. the world partition editor stopped responding and I cant load it anymore. When I try UE5 crashes and uses 20gb of ram before the crash. I can’t delete the unloaded landscape either

Hey there @RasenGanMax! Welcome back to the community! 20gbs of ram is definitely a wee bit much for a singular landscape so something bigger is causing the issue here it seems. Since your landscape is only 4 proxies deep I’m assuming it’s not massive. Does it also crash when attempting to launch the game itself? Generally it’d force the load of the asset when play starts unless it’s tied to a data layer.

I had the same problem but I think this has fixed my issue for now… :grin:
Thx :+1:

Although now I’m running into new issues… I’ll try and find a tutorial on landscape streaming proxy’s because somehow I get a region to load but then again I have the rest of the regions missing!
I created a landscape and filled the world but now I only have a smaller overall landscape and I dont quite understand why…

Hey there @papazweistein! It’s possible it could be that the regions are just too far away and are not being streamed in anymore automatically. World partition does this by default. You can check if that’s the case by disabling streaming in your world settings, but be warned, back up your project first (or at least the map) because if your world is big enough to crash your rig if fully loaded in at once, it may be a problem. However it’s excellent at letting us know if it’s a streaming issue or an issue with the proxies themselves.

If they all are visible after, it’s a streaming distance issue, if not it may have something to do with the proxies.

Hi @SupportiveEntity I disabled streaming and the landscape loaded… but it was still smaller than the original landscape that I created!
But I think this might have been my own mistake when I tweaked some of the parameters after having the first issue of the landscape missing!
Because I didn’t understand what was going on I tend to just move a lot of sliders in the hope it will fix it :joy: :man_facepalming:… but that only works half of the time :joy:
Anyway because I wasn’t 100% sure if that’s what I actually did I tried adding single segments of landscape!
So I can add single segments which probably means it was my error!
Learning by doing…

Thank you for your help!
I’m going to need lots of it in future :blush:

The cross section is the bit I added manually to check!

So I just enabled streaming again and now I get this :joy:

Its ok I’ll work around it for now since I kind of know where to look now… but it is weird though…

Haha you’ve got it then. Large worlds require streaming to be performant, so it’s best to leave that on and just load what you’ll be working with inside the world partition minimap or decide what is loaded via data layers. However data layers have a couple quirks in 5.1 just as a heads up.

If you do end up having any questions, don’t hesitate to let me know!

And I removed the mark from the “landscape”, and I was looking for my landscape for an hour.
Maybe someone will help…

Hey there @thats_mesfix! Welcome back to the community! Is your landscape missing just as this post? Does it show as unloaded in the outliner? Are you using world partition as well?

Hello! Everything is fine, I just described how I did it, i.e. I accidentally unchecked the display of the landscape and for some time I could not understand where it had gone))) I wanted to share, maybe someone also missed it. )))

NICE.

i have run into this issue, now, after creating new LandscapeRegions, and appropriately positioning them, they do not always ‘inherit’ the proxies within them. The landscape components in question happen to sit on the same boundary between two landscape regions. The problem being that they are not available to Load because they are not assigned to the region that is positioned over them. is this a spacing issue? is there a way to manually assign components to the region so that we can then load them?

seems like something is off, although they are spaced exactly like the auto-generated ones. My thoughts are that perhaps the spacing between component groups is somehow larger than the spacing between components within a group. i will play around with the numbers, and add any more info i can gather.

Update1: it is not the spacing, other rows of regions have no issues, along the same axis
Update2: the landscape component appears to actually ‘be loaded’. just not showing up in viewport.
