Sure, what is meant by custom physics, in the first post, is not using PhysX template for the vehicles but doing calculations directly in game code. PhysX is still used to handle rigid body collision and process forces. The way it works, for example with friction: we measure relative velocity, calculate necessary friction force and apply it to vehicle using AddForceAtLocation(). From there, physics engine will handle changes in velocity linear and angular velocity, rotation and position.

Not sure if I understood it correctly. In a nutshell, the difference between MMT and normal physics in UE4 is that you update your physics positions/forces/impulses during each substep, while ‘normal’ physics in UE4 updates only at the end of a full substeps cycle. That’s the novelty here as far as I understood.
This per-substep updating is only active for your nodes that you created and use in MMT and it does not mess around with the other physics in the project, right?
