Physics MeshImpostor can't work and RopeImpostor collision not good at AmmoJS Plugin

Rope impostor is made a small sphere linked together. as with other physics object, if moved fast enough, collision doesn’t get detected. Increase step count to remediate the issue.

Physics: should setSubTimeStep speed up simulation?

Hi @gbz There are many controls on time with physics and it can be complicated to get it right once you want a clear control and steps. First thing first: var physEngine = new BABYLON.CannonJSPlugin(false); the parameter determines if steps (or substeps) time delta should be fixed of not. if false, the steps (or substeps) will alsways be the same. It means having substeps with fixed time step results in simulation running faster. Let’s say you want substeps in order to improve physics resol…

What do you mean for 3?
It looks like there is collision
