Unreal Engine 5 | Open World Tutorial Using World Partition 

ue5 tutorial on dedicated server

My favourite part is world partition topic. Now even more effective ☺️

Awesome video SP, appreciate the overview, haven't gotten a chance to start messing with this just yet in preparation for my larger open world game project, but all looks super promising and I think it's going to be a massive deal to solo indies like myself when it's all said and done. Thanks again for covering this stuff :D

The trees popping in at different distances may have something to do with how foliage clusters are generated. One tree may be on a grid that is loaded, but the cluster origin lives in a different grid space, resulting in closer trees not drawing accurately, or culling out too early.

World partition is enabled by default on official release now, go to window > world partition for window popout

I think that cell size should actually be smaller to increase the resolution of what's shown/hidden as the character moves; otherwise, one would see large amounts of assets showing up all at once. With a higher resolution, "tree by tree" would be showing up, which in the end is more natural. Or am I missing something?

You need to check the box for prompt convert on open level. It will then let you convert you landscape to partition.

Thanks for making this video. I'm starting over in UE5 and this worked out great! Thanks a billion for also sharing the heatmaps

Thanks for covering this. I struggled with world composition in UE4. UE5's system looks far easier to use.

more tutorials, please!

Wow, that's reminds me Minecraft chunk loading system, really cool!

Absolutely awesome video, show us how to add the water system for a Ocean and my life is complete! Thanks for your hard work!!

I believe the reason why trees were popping up was because you placed them in one grid and then hold and dragged the mouse from one grid to another. Even tho they were placed on a different grid, they were bound to the grid you first clicked on.

Can you combine this with data layering? Maybe that could add "instances" of each world partition, so if players want to build housing in a space that is already built in, they could choose to have their current world partition phased out/a new one for them to build on? Etc

Thank you, really excited by world partition but was having trouble working this out by trial and error. This will have me up and running (!)

Tankyou

i just wanna be the first comment once in my life

Is there a version of world partition, that is following / centered on player, that reaches beyond the world partition edges, to buffer the adjacent "cells" since a players versions radius breaks a world partion barrier before the player does. Or is this handled automatically with LoD, and nanite?

Hi i want to know something, if you were to turn Something like this into a planet For Ground to Space Type Games, is there a way to Turn it into a Giant sphere while Having all the Terrain Intact?

I love your vidoes!! not sure it's my pc but your videos are usually always low volume compared to other vidoes

At 15:34 you mention about better ways to create trees, grass etc. Can you teach us? Thanks! great tutorial, this helped me a lot

I feel 10x more confident in soft soft, thanks!

Does World Partition work in Z axis too? Hoping to use it someday for real size planets.

Fantastic video. I like your teaching style

Fantastic video, you are very good explaining this. thank you

Are you available for hire?

Solution: I had to make my ThirdPersonCharacter set to "Always Loaded" in details panel. lol Thank you for this tutorial. Can you think of any reason why my streaming isn't working? I have one green square. When my streaming area no longer contains the green square, that square unloads (turns red) and I can no longer move. None of the other squares turn green or red.

You have a good voice for these videos. No homo.

Do you know if UE5 can auto cut a landscape height-map or does it HAVE to be a tiled landscape. For example if one has a 4033x4033 landscape that would be lighter on resourse's if it was 1009x1009 tiles , I'm guessing setting the grid to approx 1009x1009 it would cull objects outside the radius right to lighten the load on exsisting maps

super helpful video! thank you for creating it.

What's the maximum size a map can be using world partition? Can we still use world origin rebasing?

Thank you very much. Very useful lesson.. Please continue

It's working thanks my friend

Thank you for making this tutorial! I have a problem where my landscape tiles will disappear and reappear at various distances... some tiles will spawn FAR out, and others closer to the player will be missing...... Do you know why they would be acting up?

wow this video was playing in the background but I didn't notice until I went to watch it because the volume was so low

But can I actually make a huge open world?? It seems in theory it would work based on this, but like can I load in multiple landscapes next to each other and use this?

Critical point for video. Please check the audio output for a NORMAL system. Your video is *extremely* quiet; which I suspect is due to you using headphones with system audio turned all the way down. For comparison, any other video, at 100%, with soundboard at 33% is perfectly fine. For yours to be hearable the soundboard has to be at 50%.

It was very useful

Do some tutorial about HLOD too, i read about it and not will work with landscape, but try to use in others static mesh they talk about Automatic HLOD and Impostors in UnrealFest but i not find in Documentation.

what happens to collisions when an area, landscape area, or meshes are streamed out? If collisions disappear how can i retain collisions for characters in the area?

Great tutorial!

What is the MAX_World size we can create now with World Partition? It seems they limited the scope of what kind of world you can create with this new feature in UE5. smdh.

bro sitting across the room from the mic

Great vid! really helped!

Nice! Thanks mate!

Dude you'r life saver

I love your videos omg

Great tutorials as always!

Can you have more than one landscape tiled to make huge worlds?

Do we know what is the size limit of this system? Compared to normal ue5

Thanks for the tip! :)

This was an awesome tutorial thank you. Assuming the landscape that is not loaded is a low poly proxy mesh so you can see it still? Some of those far away "proxy?" landscape meshes are not loading when your up high they look patchy. Is there a way to make sure all the proxies load

As far as I know on UE4 u could predetermine your grid before u create your landscape

Have you managed to get this working with texture weightmaps, I see no way to import/export those?

Help! how to use contour lines? this must converted necesary into depth map?

Do you know if it works vertically as well?

you metioned it better to generate trees rocks procedually, what about grass, instance count will be really high, thank you for the greate video.

Why is it if you do Stand Alone Game Player falls through the map? Any Idea as how to stop loading character long enough to let everything load first, then load the player? Thanks for Great Videos!

10:22 do you thing we will be able to have a fps counter convert these numbers on fly for cell size and load range based off of what fps you want in a given location? static dynamic chunk knowledge of world to optimize say big city vs desert automatically?

So if I wanted to make a larger map I'd just import more tiled landscapes and put them next to each other to an arbitrary amount? Is there a limit to how large you can make the world?

hey, thank you for detailed tutorial. I want to ask something. In streaming level approach, we could create a Blueprint level which contains the bluprints, it always streams. In world partition, if we put some blueprint actore -for example they are using by a quest, does this actor return invalid?

My landscape dissapearing also with trees. How to fix that

Hi i have a question, can you use unreal engine 5 with this laptop: Acer Nitro 5 AN517-54-79L1 Gaming Laptop | Intel Core i7-11800H | NVIDIA GeForce RTX 3050Ti Laptop GPU | 17.3" FHD 144Hz IPS Display | 16GB DDR4 | 1TB NVMe SSD | Killer Wi-Fi 6 | Backlit KB | Win 11 thanks

oke and what if i whant to add extra tiles to the map the seem not to be using the world partition

It doesn't seem to work with 5.0.2, my settings don't look the same.

Does using tiled Landscapes give you any benefit over a single large landscape, now we have World Partition, asking as I'm creating a new landscape, in WM ?

Chaos destruction tutorial ? :)

In Import landascape have a setting about "world partion grid size"

thank you

From the recent Nanite presentation, they said they're potentially working on a "Landscape 2.0" system for UE5.

Great vid, sadly some things in the vid are different for 5.2, which stinks lol

I tried whole one height map not split and the engine split it for me, i think this is much better than the other method, worried is that you no longer have the option to add tessellation on landscape :( I just notice that it becomes gray.

Great video - but the clicking of the mouse is quite annoying, might need to move the mic further away

World partition does not show up and I have no idea how to sort this can’t find anything online

Is it possible to create Red dead redemption game size with UE5 ? or how big is the UE 5 map size maximum ?

Thank you 😊

So when i make the world partition, i get the same result as you. I don't have the ">" besides "world partition" Then you clip the video at 2.00, and suddenly you have the ">". How? Nevermind. You just have to save > new level > open saved level

Hi.. Smart Poly.. I Have A Quick Question?.. My Question Is what Program did you use to Create the 3 Tiled Maps?.. Thanks In Advance..

hey man ,i just discovered your channel (oviest what i was searching for) ....so i created this big world map for a tps and i filled it up with all (houses,trees, Ai enemys, etc etc )_ ....so what i do now because game is realy laggy ..is world partition recomanded or that level streaming volume ...how i do to make it less laggy besides the settings (sublevels, etc,... ) and i dont have world partition in my settings

@SmartPoly Do you know if it's at all possible to have Looping World Partitions? So If I ran in a straight line, eventually (after a specified size) I'd end up back where I started.

I try importing old level and it says it failed to convert... how long do you think till this will be fixed I believe it has to do with a lot of old code for plugins and my pre-made terrain? should I just scrap old maps wait for solution-specific convert settings?

Does this let you make infinite world sizes? Theoretically at least, beyond the puny limmits it used to be?

What are you using for building big maps? World Machine or something like that?

Is there any way to swap far terrain tiles with low res mesh ? so actually u have a far distance view but in distance instead of terrain teh tile is swapped with 3d optimized model of that tile. Does UE5 got something like this? In Unity there is asset called World Streamer that does that autmatically with a click of a button, it takes terrain, splits it and generates 3d optimized model for it to swap unloaded terrain tiles with its 3d model optimized representation

9:59 why isnt there partition streaming? using network... or just load streaming what ever area the cameras in... is this to save load times for level... why not stream nothing in and have chunks load as camera moves to place... idk

Hi smart poly. Do you know if it’s even possible to import biome regions along with heightmaps in UE5. When I try to use a multi-layered material, I get a blank grey landmass. No option to import regional heatmaps/biome maps.

Now if I have a map I already created with grass and trees and I bring it into this will it automatically make levels for it? So I don’t have e to again?

Good. thanks.

Any idea what happens when you level instance a World Partition map into a normal old-method map?

Hei, i have a laptop Lenovo Legion i5 with GTX1050 but when use UE5 in play mode, the game graphic show slow, in UE4 run smooth .. help me please

Is there a way i can turn the world partition on in an existing level/map that i have already made?

am i able to import more than one heightmap into ue5? Im trying to make a very big landscape and am stumped.

I don't understand this feature 5:13 --- If you have an open world and your character runs in a field, why would everything in front of you NOT be visible (trees, houses, mountains) and then "pops" into view when you are close? Or am I missing something? Also why have they not made this more user friendly? It feels like rocket science, when it comes to map level streaming.

cant make my country cuzz of max resolution is too small? any diea?

technology is advancing incredibly fast. Only 20 years ago you played with 2 pixels.For everything that people thought was impossible today is possible

how to connect the parts togther please ?

can we build universes with solar systems like Star Citizen with this?

can we place like adjacent layer to it like if we want to extent it

Quite useful if you have a massive map... but useless as a replacement for World Composition, since with World Partition, you can no longer add more landscapes like you could with World Composition. Fortunately, it's still available in version 3.5... I hope Unreal Engine replaces it with something that does the same but more easily and doesn't remove that function. I'm creating an open-world game and aiming to compete with the map of GTA VI, hahaha, yes, I'm very ambitious. Just creating the first city will take me a whole year or two, but my idea is to create the AAA-quality scenario by myself, even if it takes a decade to release the game ;) Anyway... the midlife crisis

Can you not set the landscape to be drawn randomly as the "grid's" are loaded?
