Hello,  
I am working on a project but i am thinking a LARGE openworld map something like 120km2.

Several questions i have here

1. can UE handle a map that large? if so what is the best settings to handle that size?
2. I will not be releasing the full map at once , I would like to work on the project section by section but release a smaller playable area for testing while the other areas are being built. How do I achieve that?
3. I would like to use a map vector image i have created in illustrator, anyone know best way to use that image? or have tutorial links?

Thank you for all the help

Hi Techhnyne,

yes, UE can handle maps much larger then 120km².  
You will need to split it up in different Landscapes.

Here you can find the recommended Landscape sizes:

> **[Landscape Technical Guide in Unreal Engine | Unreal Engine 5.6 Documentation...](https://dev.epicgames.com/documentation/en-us/unreal-engine/landscape-technical-guide-in-unreal-engine#recommendedlandscapesizes)**
>
> Understanding the construction and dimensions of Landscape Outdoor Terrain.

You can add Landscapes later.  
In your case you can use 16-bit grayscale PNG if you use software like Illustrator, since I’m not sure if it can export .r16 files.
