When I use cesium, I zoom out and the model materials fail and the model turns white. How to solve

When I use cesium, when I pull the Angle of view too far, the model material will fail and the model will become white. It looks strange and it doesn’t work very well. Have any brothers encountered this situation and solved the problem?


The first image is the effect when the viewing Angle is very far away. The second one is from close range。Thank you and look forward to your recovery of me

I can’t tell what I’m looking at in those screenshots. Can you provide detailed step-by-step instructions for reproducing this problem?
