Several Physics Constraint bugs

When using a physics constraint with skeletal mesh that physics simulation set to on following settings will not work:

  • Max Angular Velocity
  • Linear Damping
  • Angular Damping
  • Enable Gravity
  • Mass scale

Using a normal mesh instead works but when using it inside a player BP such as the FPS example player BP it behaves very strange: setting the angular limits to the following makes it pretty clear: Free, Locked, Locked. As the player starts rotating, the constraint object starts rotating as well but in the opposite direction and when you rotate then in the other direction, the object just keeps rotating in its same direction and just gets faster and it keeps going and on. It is very awkward to say at least.

This was not present in 4.7 and before. These findings originated from updating a project to 4.10 as well as trying 4.9 and 4.8. Here is that, as well as a step by step for setting up a simple physics constraint: How to make physic simulated weapons in 4.8 and up? - World Creation - Unreal Engine Forums
