How To Optimize Your Levels In Unreal Engine 5 ( Level Streaming Tutorial )

[Fafhrd]

It's usually a better idea when using scripted level streaming to use the Get Streaming Level node and call Set Should Be Loaded and Set Should Be Visible instead of the Load and Unload Stream Level nodes. The Should Be Loaded and Should Be Visible functions essentially add the sub-level to a queue to be loaded and made visible according to their priority, while the Load and Unload nodes try to load the level immediately. Also, since they're Load and Unload are latent action nodes, if you have a list of levels you want to load or unload you can't use them in a loop, as until the loading or unloading process for the first level in the list finishes all subsequent calls to that node will be ignored.

But really, you shouldn't ever be using blueprint for level streaming. Level streaming volumes are way better, and if you want more granular scripted control just call Set Disabled on the streaming volumes in blueprint instead.

i need this so much! thank you!
please feel free to share more Optimize videos

Thank you so much! When UE5 came out I did not understood this concept that well but your video made me understand it and also helped me to apply it. Especially if using Lumen and VSM Beta. I remember reaching a point where I broke the shadows of my levels due to using many small dynamic lights. I was quite frustrated back then with that issue. I made a quick test in one of my levels with this method and it works like charm! I just need to think different design-wise now. Either way, this method opened my mind to so many new possibilities! This will help both my Unreal Engine and Roblox work. Thank you deeply! What you explained here is gold to me!

This is a great and easy way to handle it without scripting, thanks a lot! 😀

My dear teacher I am wanted this tutorial! Thank you so much

Odd question, but I assume "Persistent levels" Don't affect culling right? Like, say your 3 cubes are in the persistent level, but are behind a wall and out of view. Would they still get culled out the same as any other object, or would it remain rendered? It is 2 am when I write this, so I'm sure when I wake up the answer will seem more obvious. I have a large project that consists of many floors with a good transition piece between them, helping smooth out the loading of each level, but would like to ensure it's the best way before changing things to use streaming.

Bro you are a legend thank you so much.🎧🎧

[poly_based]

hi, thanks for your great Tutorial
is this possible to use world partition and level streaming at same time?

[spunkin]

what im wondering is if this level streaming technique can be used for levels that were already created. unless im mistaken, in this video it seems like its somethings that is primarily used for brand new levels.

Thanks I haven't tried to physically do level streaming yet I wanted to research it first. Does this work for parts of landscape and dynamic lighting?

[saeedserwan]

Thank you for the video always womdered how it worked, but i thought unreal can help with lowering LOD enough so that loading screens wouldnt be neccessary anymore. Maybe im missing something. Thanks for the upload.

Great tut! Good or bad to have Main Menu level persistent?

[AfterHoursDevchannel]

OFC it works fine but I'm little confused now ;/
How does it relate to UE5 WorldPartition system and Data Layers? Doesn't they serve the same purpose- you can enable/disable datalayers?

I (probably wrongly?) thought LevelStreaming is more connected with idea of Sublevels and therefore old UE4 World Composition system, now replaced by World Partition?

Other matter I thought OcclusionCulling also works here= these blocks in second room are rendered only from the moment you began to see its first slightest element, first pixel of rendered object image?So I thought they aren't there anyway till moment I began to be able to see them.

EDIT: But now I think I see the difference- Occlusion and rendering happens and relates more to CPU/GPU operations and streaming level you have shown here is more about count of actors in the scene(level)= more MEMORY issue?

But then still I thought now WorldPartition and DataLayers deals with that?withn occlusions at back seat;)


Sorry for chaotic questionS= simple manifestation of "performance ideas" chaos I have in my mind now ;)

[BigbearDev]

Thank you!
can we replicate it so it will work separately for each player?

[raphaelmillies-lacroix]

Hi, thanks for your content !
What's the benefit compare to world partition ?
Should they be mixed for some usecase ?
Thanks !

How to get the project that contains particles with jumping and footsteps at the beginning of the video?

[screenapple]

how do you do fade in and fade out level stream appoarching closer or far away?

[aviel]

hey :) is this work with multiplayer game too? or need to set some code to make it replicated?

[agentshadow]

Thank you, could you please make third person toturiol with all details like 8 directional movment and ik system, and animations crouch and equip and unequip pistol and guns with physics properties

[zerotoerance]

but what if there are a lot of objects, will this lead to freezing or long loading when entering this trigger zone?
