Target Chain IKSettings

C++ Source:

  • Plugin: IKRig

  • Module: IKRig

  • File: IKRetargetSettings.h

Editor Properties: (see get_editor_property/set_editor_property)

  • affected_by_ik_warping (bool): [Read-Write] Affected by IKWarping: Is this IK goal affected by the stride warping (in Global Settings). Typically this is true for all feet, but not for hands.

  • blend_to_source (float): [Read-Write] Blend to Source: Range 0 to 1. Default 0. Blends IK goal position from retargeted location (0) to source bone location (1). At 0 the goal is placed at the retargeted location. At 1 the goal is placed at the location of the source chain’s end bone.

  • blend_to_source_weights (Vector): [Read-Write] Blend to Source Weights: Range 0 to 1. Default 1. Weight each axis separately when using Blend To Source. At 0 the goal is placed at the retargeted location. At 1 the goal is placed at the location of the source chain’s end bone.

  • enable_ik (bool): [Read-Write] Enable IK: Whether to modify the location of the IK goal on this chain. Default is true. NOTE: This only has an effect if the chain has an IK Goal assigned to it in the Target IK Rig asset. NOTE: If off, and this chain has an IK Goal, the IK will still be evaluated, but the Goal is set to the input bone location (from the FK pass).

  • extension (float): [Read-Write] Extension: Range 0 to 5. Default 1. Brings IK goal closer (0) or further (1+) from origin of chain. At 0 the effector is placed at the origin of the chain (ie Shoulder, Hip etc). At 1 the effector is left at the end of the chain (ie Wrist, Foot etc) Values in-between 0-1 will slide the effector along the vector from the start to the end of the chain. Values greater than 1 will stretch the chain beyond the retargeted length.

  • static_local_offset (Vector): [Read-Write] Static Local Offset: Default 0, 0, 0. Apply a static local-space offset to IK goal position.

  • static_offset (Vector): [Read-Write] Static Offset: Default 0, 0, 0. Apply a static global-space offset to IK goal position.

  • static_rotation_offset (Rotator): [Read-Write] Static Rotation Offset: Default 0, 0, 0. Apply a static local-space offset to IK goal rotation.
