I used the latest version of cesium to load 3dtile
But I found that the model was not fully loaded, and I need to pull to a specific perspective to see it. But I am using the old version of the same model, such as 1.90, and there is no problem. I tried to adjust parameters such as maximumScreenSpaceError and cullWithChildrenBounds, but it didn’t work
Hi @shuidiBeida, the way we load models changed in CesiumJS 1.97. See the blog post for an explanation of the changes.
If your model is very old, it is possible it has some features which are not supported anymore. But we are still on the lookout for bugs in the new loaders. Can you share a Sandcastle example that loads your model?
