Hi @yuxueliyuxl,

Can you please give us reproduction steps for this issue? For example, can you make the crash happen on the point cloud level in the Cesium for Unreal Samples project?

Hi @yuxueliyuxl,

No，I created a new level and configured my own point cloud 3dtiles service，url： http://121.224.73.36:9003/PointCloud/tileset.json

it is similar to the bug I found before：#1546
