Draping custom terrain leads to complete frame rate drop

Hello! I used Cesium Ion to 3D tile a set of geoTIFF files into a terrain. The terrain data itself works well in Unreal, but when I drape it with Bing Aerial the framerate drops to a point where the entire editor becomes unresponsive. Any ideas what I might be doing wrong? The asset ID is 672186.

Hi @Arkwiz,

Are you getting any logs or error messages when you drape the imagery over the tileset? Is the FPS drop immediate?
We’re looking into it, and we’ll get back to you if we find a solution.


Thanks for getting back to me. No, can’t see any error messages. It drapes fine, and then it immediately grinds to a halt.
