Gaussian Splatting Loading Exception and Incorrect Bounding Volume

[JaneLucky]

What happened?

1. Loading Exception
   A Gaussian point cloud with 24 million+ points was converted into Gaussian-format 3D Tiles. When loading it in Cesium, the following error occurs:
   "Paused before potential out-of-memory crash"

Note: The same Gaussian point cloud, when converted into point cloud-format 3D Tiles (standard point cloud), loads without any errors.

2. Incorrect Bounding Volume Display
   After loading the Gaussian-format 3D Tiles and setting debugShowBoundingVolume = true, the bounding volume is displayed incorrectly.

The wrong bounding volume may be an issue with the data itself (so it might not be an issue of CesiumJS), and may have to be tracked elsewhere. Which tool was used for generating the PLY input data?
