How to upload 3tz file to Cesium ion

I have a Cesium 3d Tiles file 1.0 (*.3tz 1.0) created… How to upload to Cesium ion.

A 3TZ file is, in fact, a standard ZIP file (with a special index structure). So when you rename this file from .3tz to .zip, it might already work.

(If not: Any error message or description of the observed behavior could be helpful).

Thanks Marco,

your suggestion is sport on!
