3dtile can load in v1.76 but can't load by v1.82

I used the same code to load the same model in the official download version 1.76 and version 1.82. Version 1.76 loads correctly. Version 1.82 has an error message:

Cannot read property ‘undefined’ of undefined

I found in ModelUtility.computeBoundingSphere the gltf.scene is undefined (in version 1.76 is commonly 0) then I saw the model param requested address is a json (should be b3dm). What is the difference between parsing 3DTiles in 1.82 and 1.76?Or what can I do to fix it?

Solved in 1.83.


That’s correct! @QianWu184 more details about 1.83 can be found here:
