Thanks for your note and for being part of the Cesium community.
Most the show/hide logic for models in CesiumJS API is exposed through the tileset, not the model Styling and Filtering 3D Tiles – Cesium
don’t want to deploy the model on orther server.
It is not required to stream 3DTiles from a separate server. This thread dives into using CesiumJS in offline mode and serving assets such as a 3DTileset from the same folder and your application Cesium Completely Offline Mode
Please let us know if this does not address your question fully and we would be happy to try to help more.
Thanks,
Luke
