Register physics step

Hi,

for the scene it is possible to registerBeforeRender().
Is there something similar for the physics engine. E.g. a registerBeforePhysicsStep() that is executed before any physic calculation happened.
I’ve seen that there is a registerBeforePhysicsStep() for a specific physicsImpostor, but is there the same functionality independent of one specific impostor?

Yep! the best candidate is scene.onBeforeAnimationsObservable
