Reposted by Danny Chapman Daniel Holden @theorangeduck.bsky.social · 25/02/2025Learned a new spring fact from my colleague @rat-face.bsky.social recently. For a critically damped spring tracking a target moving at a constant velocity, the amount of time the spring will lag behind the target is given by "halflife / ln(2)".

Physics control allows direct tweaking and modifying of a physics asset's "ragdoll behavior" on a bone-per-bone basis through blueprints, making it modifiable in runtime and highly customizable! 061
