Terrain data not cropping and instead covering entire globe?


Apologies if this has been answered before. I’ve been importing DEM data sets into my Unreal scene and have been running into an issue. Previously, when I imported terrain for a small area it would be cropped where the data for the map ended. Although, now I seem to have done something to cause any terrain data I add to cover the entire globe. It’s making it rather tricky to zoom in to my specific area of interest and to prevent terrain sets from clipping into each other. Is there a setting to fix this issue?

Thank you,

Hi @Phil_Owen,

Can you describe how you have your level setup, i.e., what Cesium objects are in the scene? From what it sounds like, the terrain was “cropping itself” without the help of a cartographic polygon, but I’m not sure what that means. Do you have before / after pictures that demonstrate this behavior?

Hi Janine,

Thank you for the reply. I have a few screenshots of what is occurring now. I have a cropped DEM that I uploaded as a Cesium online asset.

Once it is added to Unreal it fills the entire globe as you can see below:

I am considering polygons although I found it handy that it was automatically cropping based on the dimensions of the DEM I uploaded. I unfortunately don’t have screenshots of these occurrences.

Thank you,

As far as I know, Cesium ion has always created a complete globe from terrain data. The cartographic polygon should work well if you don’t want to show the whole thing, though.
