Type: array<PreviewSocketStruct>

Modifiers: editoronly


Internal variables[edit]

bBeingEdited[edit]

Used to avoid editing the same AnimTree in multiple AnimTreeEditors at the same time.

bUseSavedPose[edit]

Type: bool

If TRUE, AnimTree will always just return cached pose, rather than evaluating entire anim tree.

Type: int

Modifiers: editoronly


PreviewAnimSets[edit]

Type: array<AnimSet>

Modifiers: deprecated, editoronly


PreviewCamPos[edit]

Type: Object.Vector

Modifiers: editoronly

Saved position of camera used for previewing skeletal mesh in AnimTreeEditor.

PreviewCamRot[edit]

Type: Object.Rotator

Modifiers: editoronly

Saved orientation of camera used for previewing skeletal mesh in AnimTreeEditor.

PreviewFloorPos[edit]

Type: Object.Vector

Native functions[edit]

FindMorphNode[edit]

native final function MorphNodeBase FindMorphNode (name InNodeName)


FindSkelControl[edit]

native final function SkelControlBase FindSkelControl (name InControlName)


ForceGroupRelativePosition[edit]

native final function ForceGroupRelativePosition (name GroupName, float RelativePosition)

Force a group at a relative position.

GetGroupIndex[edit]

native final function int GetGroupIndex (name GroupName)

Returns the index in the AnimGroups list of a given GroupName. If group cannot be found, then INDEX_NONE will be returned.

SetUseSavedPose[edit]

native final function SetUseSavedPose (bool bUseSaved)

When passing in TRUE, will cause tree to evaluate and then save resulting pose. From then on will continue to use that saved pose instead of re-evaluating the tree This feature is turned off when the SkeletalMesh changes
