How to break up an already made landscapes into individual sections for level streaming

Hello everyone,

I recently started working with world composition and found that we need to tile large landscapes for level streams. My question is, is there a way to break up a large landscape that I already made into tiles for level streaming.

If you made a large landscape whats the point of breaking it up?

if you are hoping to solve performance issues by doing so, you probably won’t.
Balance the LOD to reduce overall tris count. Simplify your material or use RTVT to reduce the cost.

world composition should be used when you need to handle areas larger than 1 landscape permits.

That said.
You can export the current heightmap, split it up in something like Krita that handles 16bit files natively (ei: do not use photoshop), name the tiles up, and import them as a tiled landscape

if you are hoping to transfer the paint too, you can save out the paint layer and split them following the same methods (don’t think those are 16bit, not sure).

Another somewhat viable alternative is to just duplicate the landscape and delete components, then set up manual streaming on them.
Perhaps its the least time consuming option.
After deleting components - considering you’ll get a few engine crashes - you may also be able to resize the components without changing the actual terrain size… so you can swap the size of the base component to something smaller in size (which MAY improve performance).

MostHost LA, Thanks for your help. I figured out how to do it the way I thought it could be done.

For anyone with the same issue that I was having. Here is how to break up an already made landscape into individual components that you can use for level streaming. FYI I’m using ue4 4.26.

  • Simply click on your landscape and go to landscape mode.
  • In the manage tab look for the select tool and select your first section.
  • After you’ve selected your first section, there is another tool in this same tab called “Move”
  • This tool will separate the selected section and now you can simply assign this section to its own level that can be used for level streaming.

If you have any questions PM me and I’ll do my best to help.

Take your heightmap import into Terresculptor TerreSculptor – Demenzun Media
Use the tile creator to create a series of tiled height maps
