hello,every one.I have a 3d tiles dataset of the photomesh creation.I find I can load and render it in Cesium version 1.35.But when I load it in 1.36 or later,I get an error message,the message's content just like "An error occurred while rendering. Rendering has stopped.TypeError: Cannot read property 'replace' of undefined".So,anyone can tell me the solution?thanks.

Your tileset might just need to be updated. What kind of data is in the tiles? Buildings, or a point cloud etc?

If you have the original data, you can also re-tile it by uploading it onto Cesium ion ([cesium.com/ion](http://cesium.com/ion)) and that’ll give you a tileset you can use that has all the latest improvements.
