Syntax
uint8 bBounceAngleAffectsFriction: 1
Remarks
Controls the effects of friction on velocity parallel to the impact surface when bouncing. If true, friction will be modified based on the angle of impact, making friction higher for perpendicular impacts and lower for glancing impacts. If false, a bounce will retain a proportion of tangential velocity equal to (1.0 - Friction), acting as a "horizontal restitution".
