As the 7000th person missing a cylinder collider shape in PhysX, I believe my question may be slightly different to others.
I have a vehicle physics script dealing with everything from acceleration-, forward and sideways friction forces and so on. The vehicle is not impacted/driven by spinning wheel colliders but rather the AddForce and AddForceAtPosition methods.
The only purpose the wheels’ colliders have is to give them a physical representation and ability to collide/impact the vehicle rigidbody (they use friction values of 0).
Here’s my question, would cylindrical mesh colliders be fine if they don’t need to rotate - or would they still cause issues/introduce any instability to this type of simulation? Would a low-poly mesh work better/be more stable than a high-poly one?
