Loading 3dtile issue

Cesium for Unreal
1

I loaded 3dtile data, but its performance was incorrect
I pulled the perspective very close, but it still didn’t display properly

First, eliminate the reason for network speed
The model is actually very detailed, and it’s normal for me to load it using Cesium.js
I tried adjusting many parameters:

But it hasn’t been resolved yet
Who can help me, thank you

I’m not sure. CesiumJS suports some 3D Tiles features that Cesium for Unreal doesn’t yet, such as instanced meshes, but that probably isn’t the problem here. CesiumJS also supports some very old, pre-release versions of the 3D Tiles standard, such as tiles that contain glTF 1.0 models. But that doesn’t seem likely here, either.

How was the tileset created? Can you share similar views in both Cesium for Unreal and CesiumJS?

I confirm that there are no issues with my b3DM production process, and the loading and display of the same service Cesium.js are indeed much clearer. I would like to know if there is a limit on the number of Cesium for UE loading 3tiles? Or can light and shadow affect it?

Thank you very much for your answer

No, there is no hard limit. But it’s possible that:

  1. There is something subtly wrong with your tileset, but CesiumJS just happens to not have a problem with it.
  2. Your tileset is using a feature that is not supported by Cesium for Unreal, but is supported by CesiumJS.
  3. There is a bug in Cesium for Unreal.

I can’t tell which of these it might be without more information.
