if so, how much? would it be better to use a bazillion sphere colliders than a very tall capsule?

i would imagine that a single capsule would perform way better than a ton of spheres . that said i dont think having one large collision would affect performance that much. what are you making that has you so concerned?

i should have mentioned that i intend to simulate a rope that interact with physics and i’m pretty sure a bunch of spheres would perform poorly and having a few spheres with empty space in between makes the physics glitch out. i also read somewhere that capsules perform a lot better than cubes but they didn’t mention whether they tested different sized capsules.
