Default value: -1.0

ClothBaseVelClampRange

Property group 'SkeletalMeshComponent'

Animations

Type: AnimNode

Modifiers: const, editinline, export

This is the unique instance of the AnimTree used by this SkeletalMeshComponent. THIS SHOULD NEVER POINT TO AN ANIMTREE IN A CONTENT PACKAGE.

AnimSets

Type: array<AnimSet>

The set of AnimSets that will be looked in to find a particular sequence, specified by name in an AnimNodeSequence. Array is search from last to first element, so you can replace a particular sequence but putting a set containing the new version later in the array. You will need to call SetAnim again on nodes that may be affected by any changes you make to this array.

AnimTreeTemplate

Type: AnimTree

Modifiers: const

This should point to the AnimTree in a content package. BeginPlay on this SkeletalMeshComponent will instance (copy) the tree and assign the instance to the Animations pointer.

bConsiderAllBodiesForBounds

Type: bool

If TRUE, when updating bounds from a PhysicsAsset, consider _all_ BodySetups, not just those flagged with bConsiderForBounds.

bDisableFaceFXMaterialInstanceCreation

Type: bool

If true, FaceFX will not automatically create material instances.

bEnableFullAnimWeightBodies

Type: bool

Enables blending in of physics bodies with the bAlwaysFullAnimWeight flag set. (e.g. hair and other flappy bits!)

bForceDiscardRootMotion

Type: bool

force root motion to be discarded, no matter what the AnimNodeSequence(s) are set to do

bForceUpdateAttachmentsInTick

Type: bool

If true, attachments will be updated twice a frame - once in Tick and again when UpdateTransform is called. This can resolve some 'frame behind' issues if an attachment need to be in the correct location for it's Tick, but at a cost.

bHasPhysicsAssetInstance

Type: bool

Modifiers: const

Indicates whether this SkeletalMeshComponent should have a physics engine representation of its state.

See: SetHasPhysicsAssetInstance

bNoSkeletonUpdate

Type: bool

Skip UpdateSkelPose.

bPerBoneVolumeEffects

Type: bool

If true, when this skeletal mesh overlaps a physics volume, each body of it will be tested against the volume, so only limbs actually in the volume will be affected. Useful when gibbing bodies.

bSyncActorLocationToRootRigidBody

Type: bool

If true, will move the Actors Location to match the root rigid body location when in PHYS_RigidBody.

Default value: True

bUpdateJointsFromAnimation

Type: bool

If we should pass joint position to joints each frame, so that they can be used by motorized joints to drive the ragdoll based on the animation.

bUpdateKinematicBonesFromAnimation

Type: bool

If we are running physics, should we update bFixed bones based on the animation bone positions.

Default value: True

bUpdateSkelWhenNotRendered

Type: bool

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

Note: In the output from SHOWSKELCOMPTICKTIME you want UpdatePoseTotal to be 0 when this is FALSE for a specific component

Default value: True

FaceFXBlendMode

Type: EFaceFXBlendMode

How FaceFX transforms should be blended with skeletal mesh

Default value: FXBM_Additive

ForcedLodModel

Type: int

If 0, auto-select LOD level. if >0, force to (ForcedLodModel-1).

GlobalAnimRateScale

Type: float

Used to scale speed of all animations on this skeletal mesh.

Default value: 1.0

MinLodModel

Type: int

This is the min LOD that this component will use. (e.g. if set to 2 then only 2+ LOD Models will be used.) This is useful to set on meshes which are known to be a certain distance away and still want to have better LODs when zoomed in on them.

MorphSets

Type: array<MorphTargetSet>

Array of MorphTargetSets that will be looked in to find a particular MorphTarget, specified by name. It is searched in the same way as the AnimSets array above.

ParentAnimComponent

Type: SkeletalMeshComponent

Modifiers: const

If set, this SkeletalMeshComponent will not use its Animations pointer to do its own animation blending, but will use the SpaceBases array in the ParentAnimComponent. This is used when constructing a character using multiple skeletal meshes sharing the same skeleton within the same Actor.

PhysicsAsset

Type: PhysicsAsset

Modifiers: const

Physics and collision information used for this SkeletalMesh, set up in PhAT. This is used for per-bone hit detection, accurate bounding box calculation and ragdoll physics for example.

PhysicsWeight

Type: float

Modifiers: interp

Influence of rigid body physics on the mesh's pose (0.0 == use only animation, 1.0 == use only physics)

RootMotionMode

Type: ERootMotionMode

Default value: RMM_Ignore

RootMotionRotationMode

Type: ERootMotionRotationMode

SkeletalMesh

Type: SkeletalMesh

The skeletal mesh used by this component.

WireframeColor
