Is it possibe to fetch visible imagery layers only?

Dear Developers,

We have a website where users can display globes of several planetary bodies, and play around with country sizes:

Planetary maps are added as imagery layers.
The problem is that Cesium fetches not only the tiles for the topmost (and only visible) layer, but for all the layers, which results in endless tile loading when zooming in. (It wasn't a problem when there were only 3 layers, but now there are 10 of them, and more to come...)

Is there a possibility to influence this behaviour?

Thanks in advance,



there is an issue for this topic already.
