Hello. My understanding about rigidbodies is that one rigidbody on a root game object would result in child objects with colliders also receiving collision events, and that only one object--either the impacted object or the projectile--needed a rigidbody to cause collisions. But to get a Makinom collision machine to register collision events in order to change object variables on the impacted object, I have to put a rigidbody on each child that has a collider, which can cause some problems. If there is no rigidbody, there is a collision but no variable change (just VFX like particles colliding). Is my original understanding of colliders wrong?
