If someone could help me with this weird tile issue

Hi, please take a look at this cesium render. I have 2 problems. 1 is there a way to stop this tile popping. especially with the distant tiles. 2 if you check the video again, I think there is a problem with the tile mesh, maybe normals, not sure why I’m getting these weird artifacts across my tileset. I’m really hoping there is a check box I missed or something which can fix this issue, thank you so much for putting so much effort in this amazing plugin.

If using Cesium3DTileset, try setting maximumScreenSpaceError lower, set even less than 1 if good render device.
Lower maximumScreenSpaceError make distant tiles stay at a high resolution level.
