Tileset actor culling problem

[happy20210825]

I use unreal version’s 5.4.4,cesium for ue vesion’s 2.13.1
I loaded a tilset assest from url,but while i operated mouse ,sometime that tilset didn’t display

tileset link is : https://cdn.prj.cbim.ren/p_cloud.4dbim.vip/project/prj_362/beam-pedestal-template/tileset/10/tileset.json

I have tested it on cesium web, that’s ok

I have did these operation blew

1. add a material and set the material is two side
2. set the camera near clip plane = 1
3. set tile culling
   
   
4. set MaximumScreenSpaceError =1
5. set tile loading

With the Sandcastle (the Web/CesiumJS-based viewer), you can see that the bounding volumes do not match the geometry:

When this is fixed, it should properly display the tileset.

Here is a tileset JSON with the right bounding volume:

{
  "asset": {
    "version": "1.1"
  },
  "geometricError": 4096,
  "root": {
    "boundingVolume": {
      "box": [
        4.5018409622343825e-7,
        -0.0000022548120668375304,
        0.1,
        20.000001907348633,

        0,
        0,
        0.10000000149011612
      ]
    },
    "geometricError": 512,
    "content": {
      "uri": "b_10.glb"
    },
    "refine": "ADD"
  }
}
