Internal variables

ActiveMorphs

Type: array<ActiveMorph>

Array indicating all active MorphTargets. This array is updated inside UpdateSkelPose based on the AnimTree's st of MorphNodes.

AnimTickArray

Type: array<AnimNode>

Modifiers: const, transient

Array of all AnimNodes in entire tree, in the order they should be ticked - that is, all parents appear before a child.

AttachedToSkelComponent

Type: SkeletalMeshComponent

The SkeletalMeshComponent that this one is possibly attached to.

Attachments

Type: array<Attachment>

Modifiers: duplicatetransient, const

bAnimTreeInitialised

Type: bool

Modifiers: const, transient

If true, AnimTree has been initialised.

bCacheAnimSequenceNodes

Type: bool

Should anim sequence nodes cache the calculated values when not actually playing an animation?

Default value: True

bChartDistanceFactor

Type: bool

If true, DistanceFactor for this SkeletalMeshComponent will be added to global chart.

bDisableWarningWhenAnimNotFound

Type: bool

Disable warning when an AnimSequence is not found. FALSE by default.

bDisplayBones

Type: int

Draw the skeleton hierarchy for this skel mesh.

bForceMeshObjectUpdates

Type: bool

Should the mesh object be updated even when the component hasn't recently been rendered (fixes popping for cinematic cuts)

bForceRawOffset

Type: int

bForceRefpose

Type: int

If true, force the mesh into the reference pose - is an optimization.

bForceWireframe

Type: int

Forces the mesh to draw in wireframe mode.

bHasHadPhysicsBlendedIn

Type: bool

Modifiers: const

Used for consistency checking. Indicates that the results of physics have been blended into SpaceBases this frame.

bHideSkin

Type: int

bIgnoreControllers

Type: int

bIgnoreControllersWhenNotRendered

Type: bool

If true, do not apply any SkelControls when owner has not been rendered recently.

bNoSkeletonUpdate

Type: int

Skip UpdateSkelPose.

bNotUpdatingKinematicDueToDistance

Type: bool

Modifiers: const

If this is true, we are not updating kinematic bones and motors based on animation because the skeletal mesh is too far from any viewer.

bOldForceRefPose

Type: int

If bForceRefPose was set last tick.

bOverrideAttachmentOwnerVisibility

Type: bool

if set, components that are attached to us have their bOwnerNoSee and bOnlyOwnerSee properties overridden by ours

bPauseAnims

Type: bool

pauses this component's animations (doesn't tick them)

bRequiredBonesUpToDate

Type: int

Modifiers: transient

bRMMOneFrameDelay

Type: int

Modifiers: const

Handle one frame delay with PendingRMM

bRootMotionExtractedNotify

Type: bool

if TRUE, the event RootMotionExtracted() will be called on this owning actor, after root motion has been extracted, and before it's been used. This notification can be used to alter extracted root motion before it is forwarded to physics.

bRootMotionModeChangeNotify

Type: bool

if TRUE, notify owning actor of root motion mode changes. This calls the Actor.RootMotionModeChanged() event. This is useful for synchronizing movements. For intance, when using RMM_Translate, and the event is called, we know that root motion will kick in on next frame. It is possible to kill in-game physics, and then use root motion seemlessly.

bShowPrePhysBones

Type: int

Bool that enables debug drawing of the skeleton before it is passed to the physics. Useful for debugging animation-driven physics.

bSkelCompFixed

Type: bool

Modifiers: const

Indicates whether this SkeletalMeshComponent is currently considered 'fixed' (ie kinematic)

bSkipAllUpdateWhenPhysicsAsleep

Type: bool

When true, if owned by a PHYS_RigidBody Actor, skip all update (bones and bounds) when physics are asleep.

bTransformFromAnimParent

Type: int

Default value: 1

bUpdateSkelWhenNotRendered

Type: bool

if true, update skeleton/attachments even when our Owner has not been rendered recently

Note: you can use ForceSkelUpdate() to force an update

Default value: True

bUseRawData

Type: bool

Modifiers: const

If TRUE, force usage of raw animation data when animating this skeletal mesh; if FALSE, use compressed data.

bUseSingleBodyPhysics

Type: int

Modifiers: const

CachedAtomsTag

Type: int

Modifiers: const, transient

CachedFaceFXAudioComp

Type: AudioComponent

The audio component that we are using to play audio for a facial animation. Assigned in PlayFaceFXAnim and cleared in StopFaceFXAnim.

ClothDirtyBufferFlag

Type: int

flags to indicate which buffers were recently updated by the cloth simulation.

ClothMeshIndexData

Type: array<int>

Modifiers: const

ClothMeshNormalData

Type: array<Object.Vector>

Modifiers: const

ClothMeshParentData

Type: array<int>

Modifiers: const

Cloth parent indices contain the index of the original vertex when a vertex is created during tearing.

If it is an original vertex then the parent index is the same as the vertex index.

ClothMeshPosData

Type: array<Object.Vector>

Modifiers: const

ClothMeshWeldedIndexData

Type: array<int>

Modifiers: const, native, transient

ClothMeshWeldedNormalData

Type: array<Object.Vector>

Modifiers: const, native, transient

Type: array<Object.Vector>

Modifiers: const, native, transient

buffers used for reverse lookups to unweld vertices to support wrapped UVs.

Type: pointer

Modifiers: const, native, transient

FaceFXActorInstance

Type: pointer

Modifiers: transient, native

The FaceFX actor instance associated with the skeletal mesh component.

FramesPhysicsAsleep

Temporary array of local-space (ie relative to parent bone) rotation/translation for each bone.

MaxDistanceFactor

MeshObject

Type: pointer

Modifiers: native, transient, const

MinDistFactorForKinematicUpdate

Type: float

If non-zero, skeletal mesh component will not update kinematic bones and bone springs when distance factor is greater than this (or has not been rendered for a while). This also turns off BlockRigidBody, so you do not get collisions with 'left behind' ragdoll setups.

NumClothMeshParentIndices

Type: int

NumClothMeshVerts

Type: int

OldPendingRMM

Type: array<int>

Modifiers: native, transient, const
