Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere, Meta float BaseFrictionImpulse A friction (positional) impulse of at least this magnitude may be applied, regardless the normal force.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bOverrideFrictionCombineMode If set we will use the FrictionCombineMode of this material, instead of the FrictionCombineMode found in the project settings.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bOverrideRestitutionCombineMode If set we will use the RestitutionCombineMode of this material, instead of the RestitutionCombineMode found in the project settings.
Public variable UProperty Category Transient visibleanywhere bool bShowExperimentalProperties Experimental properties Experimental material properties are enabled via the p.PhysicalMaterial.ShowExperimentalProperties console variable.
Public variable UProperty Category, EditAnywhere BlueprintReadOnly FPhysicalMaterialDamageModifier DamageModifier  
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly float Density Object properties.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly float Friction Surface properties.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly TEnumAsByte< EFrictionCombineMode::Type > FrictionCombineMode Friction combine mode, controls how friction is computed for multiple materials.
Public variable TUniquePtr< FPhysicsMaterialHandle > MaterialHandle  
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly float RaiseMassToPower Used to adjust the way that mass increases as objects get larger.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly float Restitution Restitution or 'bounciness' of this surface, between 0 (no bounce) and 1 (outgoing velocity is same as incoming).
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly TEnumAsByte< EFrictionCombineMode::Type > RestitutionCombineMode Restitution combine mode, controls how restitution is computed for multiple materials.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly float SleepAngularVelocityThreshold How low the angular velocity can be before solver puts body to sleep.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly int32 SleepCounterThreshold How many ticks we can be under thresholds for before solver puts body to sleep.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly float SleepLinearVelocityThreshold How low the linear velocity can be before solver puts body to sleep.
Public variable UProperty Category, EditAnywhere, Meta EPhysicalMaterialSoftCollisionMode SoftCollisionMode For enable soft collision shell thickness mode
Public variable UProperty Category, EditAnywhere, Meta float SoftCollisionThickness Thickness of the layer just inside the collision shape in which contact is considered "soft".
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly float StaticFriction Static Friction value of surface, controls how easily things can slide on this surface (0 is frictionless, higher values increase the amount of friction)
Public variable UProperty Category, EditAnywhere BlueprintReadOnly FPhysicalMaterialStrength Strength  
Public variable UProperty Category, EditAnywhere BlueprintReadOnly TEnumAsByte< EPhysicalSurface > SurfaceType To edit surface type for your project, use ProjectSettings/Physics/PhysicalSurface section
Public variable FChaosUserData UserData
