I’m not sure what would cause that. Can you provide us with detailed instructions to reproduce the problem?

This is due to 3Dtiles services that do not adopt the CESIUMLAB standard

  1. Save vertex normals
  2. Material definition format
"materials":[
    {
        "alphaMode":"OPAQUE",
        "pbrMetallicRoughness":{
            "baseColorFactor":[1.0,1.0,1.0,1.0],
            "metallicFactor":0.0,
            "roughnessFactor":0.4499999988079071
        }
    }
]
  1. In Tileset, tileset.geometricError should not be too high, the recommendation is to keep 1000
  2. Draco compression is recommended
