Oh! An interesting way you solved it, i solved it by rendering out heightfield texture in tiles

No worries! Glad I could help.

You're welcome

I agree. Although this is actually the more realistic limit we can get away with at the moment i guess haha

I used Gaea for this. And i was able to make 16k res. Do you have full version?

Hey, thank you for the comments! So for this i built the landscape at Gaea's standard 16k setup for Unreal (Output node). And then i resized the exported file in GIMP/Photoshop down to 16321x16321. For height i did the calculation in the video based on the Gaea height :) Hope this helps.

@@mootzartdev ok thanks very much :}

I would say it is certainly possible. But you would have to be very strict with yourself with the amount of things you do at once. For example, I would not recommend having the entire landscape loaded at once for certain size environments. As this is the type of thing that will currently max our your gpu and cause crashes.

@@mootzartdev i was currently doing this tutorial. It said out of memory🥲.

@@mootzartdev ok ill try a different approch.

Well this is purely a method for setting up a large landscape. NPC and AI is a entire new area really. I would check out some other channels currently as i do not really have a plan for those types of videos at the moment sadly. But its worth noting that NPC/AI related stuff is a very large topic. Depending on what you want them to do of course. There are lots of 'systems' on the Epic Marketplace though that might be of help to get you going, and you can perhaps learn from them. A quick google search shows this system as a example that is currently on offer. www.unrealengine.com/marketplace/en-US/product/ai-behavior-system?sessionInvalidated=true

Thank you for sharing. I was aware of that. But I prefer to give others the ability to understand what they are doing.

In theory it shouldn't matter. Displacement should be relative to how the material is tiled. Not the size of the 'object' it is on top of. But I will have to try it and see. I have a few videos to do first.

Enabling landscape nanite is limited to slightly over 8 Sq kilometers. Anything higher crashes unreal engine. And it will use every bit of 128gbs of system ram just to turn an 8 Sq kilometer map into nanite. Plus nanite displacement is not compatible with large landscapes in 5.3, fingers crossed with 5.4 it will work with larger landscapes.

@@michaelhampton645 Oh wow thanks for the update! I agree, hopefully it receives more support in the future. I'm inclined to say it probably will considering how all out they are pursing nanite

@@michaelhampton645 Spot on. This is why im kinda waiting for full 5.4 before doing more in depth tutorials on these subjects.

@@michaelhampton6455.4 is out any tests done?

Yes it could be. It would depend on what your PC can handle

Im afraid not as its from my personal game project. If people are interested I can make a set of HMs for people to use.

I totally understand that. But how am I supposed to follow along then? You should provide some hm available to download, or at least point out some websites that provides them…😅

​@@venerabilee I sort of get your point. But I didn't even have to make this video. Height maps are a totally different area of their own and take some skill to create for them to be decent. You can generate random ones in various places though. I'll make a handful of random ones next week and find a place to provide them. As a few have asked now.

Yes. Currently in 5.3 there are lots of import bugs. It might be fine importing from file directly. But it tends to come with lots of VRAM issues. This is likely due to World Partition having to stitch the map together before it creates the proxies.

That is coming in my next video. Im running from 1k - 8k setups.

Yeah for large environments with high res, you generally have to do it in chunks or have a machine that can handle it Vram and ram wise.

Some things snap if you have not set other settings correctly. Sorry for the late reply.

@@mootzartdev no, it was just that my level didnt have world partition

@@amerboss99 Ahhhh ok. Glad you figured it out

This 30x30 would be 900km² The calculation for you would be first based on what resolution heightmap you want to start with. If you have a 8129x8129 resolution heightmap for example.. you would try the following... 8000 x 100 / 8129 = 98.4 98.4 would be what you set the x,y axis of your heightmap input. This would obviously scale down your heightmap to make exactly 8kmx8km ie 64km².

@@mootzartdev Thank you so much

Is this with landscape material on it ? If so its because you have not applied the paint layer properly. Go to Landscape Mode > Paint > and then next to the main paint layer on the menu below. Hit the small plus icon which will give you the option to either chose a already created paint layer.. or you can make one there and then. It should work after that. If its not this. And there is no landscape material on there... then I would have to know more.

Hey! I only have one technically which is this one targeting a more 'complex' setup. The others are more specific to different elements of the process.

@@mootzartdev Hello, at 21:07 in the video, I noticed the Landscape Region, a unique world partitioning feature specific to UE5.3. I'd like to ask about the role of the Landscape Region. Why are there four proxies, and I didn't see you setting them up?

@@yujack5910 kzfaq.info/get/bejne/hcV-pdWJqNCmpJ8.html This video i sort of explain them with how i think they are intended to be used. Basically they are for general loading and unloading. But some comments suggest they can be used in different ways.

I have a RTX 4090, 128gb RAM and a very high spec cpu. So it does make things a lot easier for me at the moment.

The one i used is from a personal project that i cant share im afraid. I used Gaea to make my heightmap. Perhaps i should make a tutorial on it. There are not many very good free options out there really.

@@mootzartdev hm okay sad haha, well thanks for the answer. Yeah a Tutorial on it would be very cool!

Generate one using perlin noise algorithms

Sorry for the late reply. It really does depend on your end goal. What is the environments target? Video games, Cinematic film? Each one would require a different approach with regards to optimise it for game or squeeze the best results for cinematics. But as you mentioned that it is not at ground level. There are lots of approaches to this. It would really be worth checking out using real world data as a input for your landscape etc. But ultimately id need to know more about the target/end goal for the project.

@@mootzartdev Sure... And thanks. I'm creating a video for church, but I do not want it to be videogame-esque. I'm thinking more documentary-level? Although some videogame imagery approaches that. The area's about 16.2mi square, from the ancient town of Nazareth to the eastern shore of the sea of Galilee. We'll be flying ~500' off the ground, in a two-minute span. I want it to be as photo-real as possible, but am prepared to get 90% there and be happy with that. Currently, I have satellite data that has deformed a large plane in Maya, using real-world units. The plane is as high-rez as Maya seems to be able to stand (~3,700 faces squared). Currently, I have about 15 variations of houses and other structures, and am starting to paint them in Painter. They are low-rez for sure, but I'm hoping they hold up in the final product. Eventually, I'll multiply these and spread them around in the various towns we'll be flying near. I'm planning to "paint" trees from Megascans or other sources within UE5 once the terrain and villages / towns are completed within Maya. The water presents another problem, but one thing at a time. The terrain texture concerns me and I'm unsure what I'm going to do yet. Does this help or just add to the confusion? LOL

Thanks! Im afraid i cant share this file as its from a personal game project.

👍@@mootzartdev

Yes. If you turn off edit layers you can go much bigger. But this essentially voids the 'modern' features of the UE5 setup. I would not recommend using a heightmap over 16321 unless your machine is absolutely insane specs. Which the average person has not got. So really, even the one from my demo vid here, is not the best example for the average person. I have done tests.. and generally 8k maps are the best (single heightmaps) and then tiled might be the way to go. However world partition is not designed for tiled. As it requires so much memory to complete the task. It has to essentially stitch them into one heightmap to then create the proxies. Which is a backwards way to do world partition terrains. hope this helps.

Yeah the issue really is how they decided to divey up tasks. World Partition takes loads of memory in the first place as it has to break up the input in proxies. Where as before the user would usually make tiled landscapes externally. So now tiled even takes more memory then the old method because UE has to stitch the tiles together to then break them up again into WP proxies. So they will now have to figure ways of making that process better. It has certainly improved a ton since 5.0. but a long way to go for them to figure out other methods. They need to create a tiled hybrid for WP. Where you can use the titled method but you assign quadrants perhaps for inputing and it treats those quadrants as tiles which it breaks up, rather then stitching them together to then break up. There is also the issue with methods for making heightmaps that are bigger then 16k etc and if its worth it at the moment etc. I would say its nearly never worth using 16k .. even if we can scrape together a scene using it.. most people wont be able to run it with their machines etc

Hey. I have a beast of a machine really. 128GB RAM + RTX 4090 with 24GB VRAM. The hard truth is that large open worlds are not easily possible on lightweight machines.

Could you do a tutorial on how to optimize big maps?@@mootzartdev

@@mootzartdevJak 2 ran on the potato ps2 and had a huge map, it’s about optimizations dawg u don’t need 128 GB of ram

@@Criteon hahaha i don't think you understand mate. This is regards to importing a 16321 resolution heightmap in unreal engine 5. Not running it when it's optimised. For starters Jak 2 map mostly consisted of meshes and extremely low resolution terrains. It's a totally different thing all together. Check the documentation for Unreal Engine or attempt this yourself and see for yourself.

@@mootzartdev I know, that’s the point, low resolution terrains, you said “large open worlds” not large resolution so this is just ur ego talking lol, if ur landscape is mostly flat u can get away with low res

Indeed. I exported a Gaea height map at 16k. Then simply changed its scale inside of G.I.M.P (or can use Photoshop) to 16321x16321. But you can use lower resolution heightmaps if you want to. But might not get the detail you want if you are scaling up to very extreme scales. And of course the import settings may require some adjustments to what is shown here.

@@oshavlfarms7239 Jump into the discord mate. Feel free

@@mootzartdev which one??

No point in 5.3. I'll wait till 5.4.

@@mootzartdevHow will that issue be resolved in 5.4?

@@sifudarryl I can't even say for certain it will be resolved. There are lots of bugs with 5.3 and we can only hope they are fully fixed in 5.4.

To have the landscape always loaded, you can de-select the Spacial Loaded checkbox in the Landscape details panel.

Making sure the landscape proxies are not set to spatially load is 1 way to stop the disappearing landscapes, but if you're having the actual bug where landscapes disappear then make sure the level is saved and there is a setting asking if this is the main world and make sure it's checked or set to main world. It took me months to find a solution for this bug.

Its related to the new World Partition system. If im correct in saying.. it has to take the image you input process it and break it up into parts (proxies) which just seems to take a fair amount of resources. Its even worse if you attempt to use tiled setup. As it has to stitch it together to then break it up again. So its why they suggest generally to use solid heightmaps for World Partition.
