Question by bpears · Aug 26, 2013 at 05:15 AM · rigidbodypivot-point

Does pivot point position matter for rigidbody?

Probably a dumb question but.. Does pivot point position matter for rigid body, and the forces applied to it? If the pivot is far away from the actual mesh, I wouldn't want to have some force that's near the pivot moving the actual mesh around. Like an explosion.

Guess I'm just not sure how Unity calculates rigidbody stuff.

Interesting question. It's the collider(s) that are important to rigidbodies plus the setting of Rigidbody.centerOfMass. Since changes in Rigidbody.centerOfMass are relative to the pivot, then in a round-about way, pivot can have an impact:
