How to Create a MASSIVE Open World Landscape (100 km2 map) - Unreal Engine 5 Tutorial

Hello there! We will be learn how to create a large Open world landscape in this video of size 100km2 using Unreal Engine and Gaea using heightmap.

At the end, We will create another Massive world of 10,000 km2 map and push UE5 to it's limit.
Using the same, you can create a open world of any size in Unreal be it 16x16 km, 32x32 km or 52x52km.

Hey Guys! I've created a Patreon page for extra content and support.

"We are going to create a whole country with this" Idk why this just absolutely killed me 😂

This is a masterclass in both using Gaea properly and generating Open World maps in Unreal 5, thank you.

[MrKoffeeKup]

Oh my god thank you! It has been so long since I found a tutorial of this quality. Your art looks beautiful and inspiring. You just helped me get back into my own projects!

[sirvazo]

Very useful information for a UE5 & Gaea novice like myself. I’ve subscribed and am looking forward to learning more from you 😀👍

[emrahozcicek]

This guy has pretty useful tutorials, highly recommended, thank you mate!

[TheMadKid]

that calculating inside UE5 when imoporting didnt know you can do that is freaking awesomeeee thank you!!!

[Apok_Alyptik]

this was way more helpful than just making a big map, thank you for your videos

[Alluvion]

Lawdamercy ive commented on one of your other videos about having trouble exporting, UNF does great explanations like you did but was using an older version of Gaea which confused me or maybe didnt fully explain how to export. So I was able to finally export my world into UE5! Thanks <3

[YOGESHKUMAR-ryfz]

This deserves a sub, amazing tutorial

[frankcastle]

much appreciated tutorial was at a perfect pace

[AiramKahless]

Can you push the terrain resolution with the "Split" method? If i would pick 8129 as resolution and 3x3 tiles imported on a 8219x8129m terrain, would be each height information 0, 33m²?

Hi Klaus, thanks for your content. I have a question about a tiled heightmap of 15135×15135px so 1009x1009 for each tiled image. If I put the x_0 y_0 into the engine it puts the whole 15K heightmap and the engine crashes after the import because of memory. Do you know about this bug and how to avoid it. With WC in UE4 this didnt happen now with WP it seems not so easy. Could please help me? Thx BR Ivan

Exactly what I was looking for, but is it possible to make the flow mask without using Gaea? I would like to do it in UE5 if possible (maybe using an algorithm in C++, or a plugin)?

[nerdherbs]

Thank you i know how to create world landsape but didnt knew how to texture it, learned somthing👍🏻

[_anirbanroy]

Dear author, I wanted to ask. I work with the creation of a landscape, according to the world composition system. Engine, version 4.72 but I do not see any difference with the 5 engine for my work. And I have a question. I imported an elevation map and divided it into 8 honors of 1 kilometer. Now I need to import 2 more height maps of 1 kilometer each. The reason I want to make a gorge and go to the second level through the script at the end of the map. How to do all this work in 1 layer and 1 level? When I load more heightmaps, they automatically make a new layer. I need 1 layer and 1 level.

[FPChris]

Gaea has to be the most artist unfriendly program Ive ever seen.

I really want to know how to handle the two seperate landscapes.I want to create different terrains in my map, like desert and forest, but one landscape has many layers is hard to manage.
Could you please add this context to your tutorial?
