Setting GLTF model animation to a specific keyframe

Hi !

I’ve been trying to work with Cesium animation system and couldn’t make it work the way I want.
Basically, I have my GLTF file with some animations. What I would want is to be able to set an animation to a specific keyframe. In my use case, I cannot rely on Cesium’s date system to handle how an animation is played. These animations are used to handle aircraft animations such as landing gear opening/closing etc which are computed internally…
I cannot play around too much with the current day time since we use the daylight cycle to handle the scene lighting etc.

Thanks !
