Variables

	Name	Description
bool	bOverrideFrictionCombineMode	If set we will use the FrictionCombineMode of this material, instead of the FrictionCombineMode found in the project settings.
bool	bOverrideRestitutionCombineMode	If set we will use the RestitutionCombineMode of this material, instead of the RestitutionCombineMode found in the project settings.
float	Density	Object properties.Used with the shape of the object to calculate its mass properties.
float	DestructibleDamageThresholdScale	How much to scale the damage threshold by on any destructible we are applied to
float	Friction	Surface properties.Friction value of surface, controls how easily things can slide on this surface (0 is frictionless, higher values increase the amount of friction)
TEnumAsByte< EF...	FrictionCombineMode	Friction combine mode, controls how friction is computed for multiple materials.
FPhysicsMateria...	MaterialHandle
UDEPRECATED_Phy...	PhysicalMaterialProperty
FPhysxUserData	PhysxUserData
float	RaiseMassToPower	Used to adjust the way that mass increases as objects get larger.
float	Restitution	Restitution or 'bounciness' of this surface, between 0 (no bounce) and 1 (outgoing velocity is same as incoming).
TEnumAsByte< EF...	RestitutionCombineMode	Restitution combine mode, controls how restitution is computed for multiple materials.
TEnumAsByte< EP...	SurfaceType	To edit surface type for your project, use ProjectSettings/Physics/PhysicalSurface section
float	TireFrictionScale	DEPRECATED - Overall tire friction scalar for every type of tire.
TArray< FTireFr...	TireFrictionScales	DEPRECATED - Tire friction scales for specific types of tires.

Constructors

Functions

	Name	Description

Overridden from UObject

	Name	Description
void	FinishDestroy()	Called to finish destroying the object.
void	PostEditChangeProperty ( FPropertyChangedEvent& PropertyCha... )	Called when a property on this object has been modified externally
void	PostLoad()	Do any object-specific cleanup required immediately after loading an object.
