3D Tiles data works unreasonable with Cesium 1.50

1. A concise explanation of the problem you’re experiencing.

I have writen a tool to generates 3d tiles data (b3dm format) and the data was works fine on cesium previous release such as 1.46 but not on 1.50. The issue is when loading the data attached by


it could be colorized when the cursor is on the model ,while loaded by the

it could not work even the wireframe display could not work.

The asset.version (0.0 or 1.0) and the content.url (or content.uri) is not the reason of this issue since I have test both type. Is there any other reason that could cause this issue?

When you say “could not work”, do you mean it throws an error? If so, what’s the error?

Looking through the changes list (https://github.com/AnalyticalGraphicsInc/cesium/blob/master/CHANGES.md#146---2018-06-01) I don’t see any breaking changes with the way CesiumJS loads 3D Tiles. If you haven’t already, it might be worth trying ion’s tiling tools (https://cesium.com/ion/) to see if that works well for you.

yes, I have checked the CHANGES and find nothing breaking changes too. Here the "could not work " is not to say there will throws an error, but the model will not change the disaplay mode to wirefram. Since the same data will works fine on previous release, I am wondering if there any bugs on Cesium 1.50 or some encode error in my data.

Can you try uploading your original data to Cesium ion and checking if the resulting tileset works? If it still doesn’t, then it’s definitely an issue on our end and we can investigate a fix.
