Syntax
USTRUCT (
Meta=(DisplayName="Basic FABRIK", Category="Hierarchy", Keywords="N-Bone,IK", NodeColor="0 1 1"))
struct FRigUnit_FABRIKItemArray : public FRigUnit_HighlevelBaseMutable
Remarks
The FABRIK solver can solve N-Bone chains using the Forward and Backward Reaching Inverse Kinematics algorithm. For now this node supports single effector chains only.
Variables
| Type | Name | Description | |
|---|---|---|---|
   |
bool | bPropagateToChildren | If set to true all of the global transforms of the children of this bone will be recalculated based on their local transforms. |
   |
bool | bSetEffectorTransform | The option to set the effector transform |
   |
FTransform | EffectorTransform | The transform of the effector in global space |
   |
