Object that disappears when rendering

Hello,

I make a 3D animation with cesium, and during my rendering, the tennis ball and the satellite disappear, I don’t know why

In the viewport, everything works perfectly

Viewport :

Final render :

The ball disappears when the camera is high in the sky

Thank you

I guess the cause might be that the tennis ball is not a georeferenced actor. I would suggest that when you can see the tennis ball in Editor , make sure its mobility of Transform is movable, then add a Cesium Globle Anchor on it.
