Unreal Engine 5.3 - 30kmx30km Tutorial - Open World Landscape Tutorial

This video demonstrates setting up a large open world landscape for Unreal Engine 5.3 using world partition. This includes avoiding bugs, doing calculations and importing heightmaps. As well as a short demo of the landscape. I use Ultra Dynamic Sky for the quick and amazing lighting setup!

Scale Up Method Calculations:

X,Y Axis: (Desired KM x 100 / HM Res)

30km Calculation Example using 16321x16321:

30,000 x 100 / 16321 = 183.8122664052448

Z Axis: (Height x 100 / 512) or (Height x 100 x 0.001953125)

5000 x 100 x 0.001953125 = 976.5625
or
5000 x 100 / 512 = 976.5625

You sir are a legend! I've been fighting my way through all possible resolutions, sizes, scales, options, plugins, everything, and couldn't get past 32 fps. Creating the landscape first, then importing the heightfield solved the issue completely, now hitting a solid 120 FPS, with materials applied, not a single hitch or drop in fps!

Running on UE 5.4 (which also has the same issue as previous versions).

Many thanks for the video!

Thank you for your videos, I tried out World Parition back in 5.1 and the lack of tutorials, guidance from Epic was frustrating, looks like its better now

Well done!! I just imported a 50km x 50 km of the island of Oahu! Thanks so much... always crashed... never thought of creating the landscape first and then applying the heightmap!

Regarding the second height calculation, 100 / 512 is equal to 0.1953125. Because you multiply by 100 you need 0.001953125. You could skip the multiplication by 100 and only have height * 0.1953125.

2:40 the res it perfect actually. Once you apply auto material, displacement, and the rest of it.

If I have 2 maps (.umap), how can I use World Partition to loading them? I've done this before on a level streaming, but it doesn't work with WP.

Hello, thank you for your video. which programm do you use for your heightmap creation ? At the moment i use gaea but it has a limited to 8k res. Best regards

hello suggest me system req for unreal game I'm so much confused when choosing hardware please.

[touristhawk]

is there any difference importing the heightmap after creating landscape first?

@mootzartdev one question .about my pc.
ryz 5 5600x with 16gb 3600mhz and rtx 3060.
these softwares runs but will i be able to make large landscapes with my pc

Great tutorial. How does this work with landscape tessellation? A key feature with UE5.3 (further established in the upcoming UE5.4) is applying material tessellation directly on to landscapes, but considering you are literally scaling up the landscape proxies, wouldn't this mess with materials and potentially break the potential for landscape tessellation? For instance, if I wanted to use this method to make some ridiculously large sized open world (think the map from Ubisoft's The Crew), would I still be able to utilize landscape tessellation/nanite for all that extra detail?

[CruelCrusader]

wouldn't changing the scale value after generating the landscape be less impactful on the computing?

[GamesStudio]

Nice, what kind of graphics card, CPU and RAM do you have?

[eligijuspranskunas]

what settings for 4km x 4km map? and what height should fit the best ?

[lolaswift]

how do we handle spawning and despawning npcs, AIs and other game objects in this setup? thx

[mrconcept]

Hi thanks for this excelllent vidoe. Could you provide the Gaea height map export settings you used and terrain definition etc?

[yujack]

Hello, may I ask if there is any difference between your four "Open World Tutorials"? I have read your first one and I didn't quite understand it. Sorry

[broseidonx]

So when I load my regions, they are all black. Any way to fix this?

[reallate]

Btw you can also just paste the entire calculation into the ue field and it will calculate it as well

Hello, loved your video just have one doubt, what if I have to create a map size of pubg big map ie erangel map. They say it's 8km×8km. Ie 64km². What are the configuration and values for that. I've created almost 10-20 projects and deleted coz I messed up. I'm so confused in these km values. Please help me.
PS - you might find it stupid question but pubg biggest map 8km×8km ie 64km² is bigger or smaller than the map you created. Awaiting for your reply. Many thanks again
