Error loading tileset after updating Cesium

Cesium for Unreal
1

After I updated Cesium to latest version on UE 5.2.1 I keep getting same error while trying to load 3D tileset from local URL. Error in question is: "LogCesium: Warning: [2024-06-28 13:38:20.380] [warning] [ErrorList.h:91] Warning when loading file:///C:/Users/filename/Data/c01/d220.b3dm:

  • Attribute accessor.count doesn’t match with number of decoded Draco vertices."

Tileset loads in UE normally but one I start moving and loading higher LOD I keep getting this error. Tilesets that were loaded in previous projects keep getting same error message even though they worked normally before updating Cesium.

Hi @matija_v, welcome to the community!

That’s a warning indicating a problem with your tileset. It’s not correctly conforming to the specification for the KHR_draco_mesh_compression glTF extension. You can eliminate it by fixing the tileset (perhaps by regenerating it with a newer version of whatever tool produced it, or by using a different tool).

Or you can just ignore it, because it’s a warning not an error.
