I think dynamicScreenSpaceError for 3Dtiles not working. I set dynamicScreenSpaceErrorDensity, Factor but not applied. As you can see console log at I attached sandcastle sample.

dynamic_true_00001

After finished loading. Set dynamicScreenSpaceErrorDensity is working in Chrome developer tool's console.

I think you may need to turn off foveatedScreenSpaceError since that interferes. The 3D Tiles inspector should also make this easier to test: viewer.extend(Cesium.viewerCesium3DTilesInspectorMixin);

Although even after turning it off I still can't determine for sure if the dynamic SSE changes are taking effect so I'm leaving this open.

For context you can read a bit about the changes in traversal (the foveated SSE) that kind of supersede dynamic SSE here: https://cesium.com/blog/2019/05/07/faster-3d-tiles/

Hi Omar. Although set foveated SEE to false, dynamic SSE parameter is not applied. I just read your comment's post. You mean foveated SSE is more powerful than dynamic SSE ?? foveated SSE and dynamic SSE are can't be used at the sametime??
