Hi @zdd900224, welcome to the community!
In the past, we’ve had people post about issues with their point clouds, but it turned out that they were tiled with the wrong orientation. For example: Point cloud data loading error. So my first question is to ask what you used to generate this data—it could be related.
If that isn’t similar to your problem, though, let us know. We would still appreciate more detail so we can diagnose your issue. In particular:
- Can you share a screenshot of the incorrect rendering?
- Do the b3dm and pnts tiles belong to the same Cesium3DTileset?
Thank you in advance!
