Preloading terrain/ tiles along path?

I am using CesiumJs for a movie clip. A CZML with a timeline let's the camera fly along a pathline and then zoom in.

Is there any way to precache/ preload/ prerender the satellite tiles and the terrain along this pathline?

Without it won't look very nice because when the camera moves along the pathline the tiles are washed out and the terrain is poping in...

Thanks for any suggestions!

In case it is possible to perform/run your flight twice or more, you can set the
viewer.scene.globe.tileCacheSize

``

to a high number and have Cesium cache the tiles.
You should then record the clip the after the first flight.
