Hello everyone.
I will try to explain my problem. When a run my code, the two plates of the top ( red and green) are interactive (on click) and move correctly. If I play the animation ( on the top left ), this interactivity no longer works as before and i want this interactivity works like the first time.
I set up a playground so you can see the problem there: Babylon.js Playground
Sorry for my bad english, if you don’t understand something don’t hesitate to ask me.
Thank you for your help.
