data is OSGB 3DTileSet, when using viewer.scene.mode = Cesium.SceneMode.SCENE2D;
change to 2D View, tile display error,how to solve this problem

Please suggest.

Hi @zy1,

I think you experience normal distortion of 3D to 2D. Look at this image for clarification. The circles are all the same size in reality.

To prevent this you have to use enableModelExperimental: true while loading your tileset. You can look at this pull request: Add 2D / CV support to tilesets using ModelExperimental by j9liu · Pull Request #10384 · CesiumGS/cesium (github.com).

Best, Lennart

Hi @lennart.imberg
thank you very much for your suggestion.

I upgraded the API to 1.95, and then added enablemodelexperimental and projectto2d attributes to the large tileset, and then it’s OK
