I’m using r3f with rapier, how can I make my rigid bodies stay insync with my animated mesh. By insync I mean follow the mesh.

As far as I know, it’s all about a functionality that is not built-in, so it’s not a feature in Rapier at all. You have to work on it yourself, as I’m facing the exact same problem.

Edit: You can just add `debug` attribute to the `Physics` tag to see that the collider won’t change at all, as its shape just shows the first-render-version of it…
