Ue5 loads cesium, close to the ground, the map flashes

Hello
I have a problem. When I use ue5 to load the cesium map, when I am close to the ground, the map keeps flashing. When I use ue4 4.27, everything is normal. Have you encountered this situation?

Hi @RFF,

I’m not seeing this issue on my end. Are you seeing this on Cesium World Terrain? And is it still happening on the most recent plugin version?

Hello
When I used my own URL(http://122.195.60.10:9003/terrain/isFcgn1O/layer.json) in “source”. It flickers when it gets close to the ground.
