Ok so the animation group is not ending because you call `play(true)` so in loop mode. And the animations are set to LOOPMODE\_CONSTANT, meaning that they will forever loop with a constant value and thus the animation group will never end.

Several options:

- Do call `playe(false)`
- Use animation events ( [Advanced Animation Methods | Babylon.js Documentation (babylonjs.com)](https://doc.babylonjs.com/features/featuresDeepDive/animation/advanced_animations#attach-events-to-animations)): [Babylon.js Playground (babylonjs.com)](https://playground.babylonjs.com/#7UR1VR)
