Variables

	Name	Description
float	AnimPhysicsMinDeltaTime	Min Delta Time below which anim dynamics and rigidbody nodes will not simulate.
bool	bDisableActiveActors	If true, physx will not update unreal with any bodies that have moved during the simulation.
bool	bDisableCCD	If true CCD will be ignored.
bool	bDisableKinematicKinematicPairs	Whether to disable generating KK pairs, enabling this speeds up contact generation, however it is required when using APEX destruction.
bool	bDisableKinematicStaticPairs	Whether to disable generating KS pairs, enabling this makes switching between dynamic and static slower for actors - but speeds up contact generation by early rejecting these pairs
bool	bEnable2DPhysics	Can 2D physics be used (Box2D)?
bool	bEnableEnhancedDeterminism	If set to true, the scene will use enhanced determinism at the cost of a bit more resources.
bool	bEnablePCM	Enables persistent contact manifolds.
bool	bEnableShapeSharing	Enables shape sharing between sync and async scene for static rigid actors
bool	bEnableStabilization	Enables stabilization of contacts for slow moving bodies.
float	BounceThresholdVelocity	Minimum relative velocity required for an object to bounce.
bool	bSimulateAnimPhysicsAfterReset	Whether to simulate anim physics nodes in the tick where they're reset.
bool	bSimulateSkeletalMeshOnDedicatedServer	If true, simulate physics for this component on a dedicated server.
bool	bSubstepping	Whether to substep the physics simulation.
bool	bSubsteppingAsync	Whether to substep the async physics simulation.
bool	bSupportUVFromHitResults	If true, store extra information to allow FindCollisionUV to derive UV info from a line trace hit result, using the FindCollisionUV utility
bool	bSuppressFaceRemapTable	If true, the internal physx face to UE face mapping will not be generated.
bool	bWarnMissingLocks	Whether to warn when physics locks are used incorrectly.
FChaosPhysicsSe...	ChaosSettings	Chaos physics engine settings
float	ContactOffsetMultiplier	Contact offset multiplier.
FBroadphaseSett...	DefaultBroadphaseSettings	If we want to Enable MPB or not globally.
TEnumAsByte< ES...	DefaultDegreesOfFreedom	Useful for constraining all objects in the world, for example if you are making a 2D game using 3D environments.
float	DefaultFluidFriction	Default fluid friction for Physics Volumes.
float	DefaultGravityZ	Default gravity.
TEnumAsByte< EC...	DefaultShapeComplexity	Determines the default physics shape complexity.
float	DefaultTerminalVelocity	Default terminal velocity for Physics Volumes.
TEnumAsByte< EF...	FrictionCombineMode	Friction combine mode, controls how friction is computed for multiple materials.
float	InitialAverageFrameRate	Physics delta time initial average.
float	MaxAngularVelocity	Max angular velocity that a simulated object can achieve.
float	MaxContactOffset	Max Contact offset.
float	MaxDepenetrationVelocity	Max velocity which may be used to depenetrate simulated physics objects. 0 means no maximum.
float	MaxPhysicsDeltaTime	Max Physics Delta Time to be clamped.
float	MaxSubstepDeltaTime	Max delta time (in seconds) for an individual simulation substep.
int32	MaxSubsteps	Max number of substeps for physics simulation.
float	MinContactOffset	Min Contact offset.
TArray< FPhysic...	PhysicalSurfaces	PhysicalMaterial Surface Types.
FRigidBodyError...	PhysicErrorCorrection	Error correction data for replicating simulated physics (rigid bodies)
int	PhysXTreeRebuildRate	The number of frames it takes to rebuild the PhysX scene query AABB tree.
int32	RagdollAggregateThreshold	Threshold for ragdoll bodies above which they will be added to an aggregate before being added to the scene
TEnumAsByte< EF...	RestitutionCombineMode	Restitution combine mode, controls how restitution is computed for multiple materials.
int32	SimulateScratchMemorySize	Amount of memory to reserve for PhysX simulate(), this is per pxscene and will be rounded up to the next 16K boundary
float	SyncSceneSmoothingFactor	Physics delta time smoothing factor for sync scene.
float	TriangleMeshTriangleMinAreaThreshold	Triangles from triangle meshes (BSP) with an area less than or equal to this value will be removed from physics collision data.
