I created this animation using only vanilla commands and Display entities. No mods or resource packs. Only Datapack.

The models and animations were created in my own free online tool – BDEngine, and exported as a datapack with ready-made functions.

The development involves a new, as yet unpublished camera animation function that uses teleportation of the entity's display(camera), using teleport_duration.

The sound in the video was added during editing.
