Packaging and Shipping certain area

Hi all,

I’m trying to make a simple third person BP game on unreal4.27 using Cesium World Terrain and OSM Building.
I only want the geo info of a small town so that I can keep the game file size small.
Is there a way to cut the region out from Cesium World Terrain/OSM Building and use just that area for packaging?

Thank you!

Hi @nomadicshinoda, welcome to the forum!

Because of the way that 3D Tiles are streamed into the engine, larger areas don’t actually impact the game file size. All of the data is loaded dynamically during play.

That being said, in the most recent update to the plugin, we added the capability to invert Cartographic Polygons. You can apply a Cartographic Polygon over the area you wish to use by following this tutorial: Clipping Tilesets – Cesium
Once you’ve applied the polygon and overlay to the tileset, you can use the Invert Selection parameter on the overlay component to exclude everything outside the selection. Any tile fully outside your selected area will not be loaded at all.
You can read more in the changelog.

Let me know if this works for you!
