Parameters

type (enum in ['CAMERA_SOLVER', 'FOLLOW_TRACK', 'OBJECT_SOLVER', 'COPY_LOCATION', 'COPY_ROTATION', 'COPY_SCALE', 'COPY_TRANSFORMS', 'LIMIT_DISTANCE', 'LIMIT_LOCATION', 'LIMIT_ROTATION', 'LIMIT_SCALE', 'MAINTAIN_VOLUME', 'TRANSFORM', 'TRANSFORM_CACHE', 'CLAMP_TO', 'DAMPED_TRACK', 'IK', 'LOCKED_TRACK', 'SPLINE_IK', 'STRETCH_TO', 'TRACK_TO', 'ACTION', 'ARMATURE', 'CHILD_OF', 'FLOOR', 'FOLLOW_PATH', 'PIVOT', 'RIGID_BODY_JOINT', 'SHRINKWRAP']) –

Constraint type to add

  • CAMERA_SOLVER Camera Solver.

  • FOLLOW_TRACK Follow Track.

  • OBJECT_SOLVER Object Solver.

  • COPY_LOCATION Copy Location, Copy the location of a target (with an optional offset), so that they move together.

  • COPY_ROTATION Copy Rotation, Copy the rotation of a target (with an optional offset), so that they rotate together.

  • COPY_SCALE Copy Scale, Copy the scale factors of a target (with an optional offset), so that they are scaled by the same amount.

  • COPY_TRANSFORMS Copy Transforms, Copy all the transformations of a target, so that they move together.

  • LIMIT_DISTANCE Limit Distance, Restrict movements to within a certain distance of a target (at the time of constraint evaluation only).

  • LIMIT_LOCATION Limit Location, Restrict movement along each axis within given ranges.

  • LIMIT_ROTATION Limit Rotation, Restrict rotation along each axis within given ranges.

  • LIMIT_SCALE Limit Scale, Restrict scaling along each axis with given ranges.

  • MAINTAIN_VOLUME Maintain Volume, Compensate for scaling one axis by applying suitable scaling to the other two axes.

  • TRANSFORM Transformation, Use one transform property from target to control another (or same) property on owner.

  • TRANSFORM_CACHE Transform Cache, Look up the transformation matrix from an external file.

  • CLAMP_TO Clamp To, Restrict movements to lie along a curve by remapping location along curve’s longest axis.

  • DAMPED_TRACK Damped Track, Point towards a target by performing the smallest rotation necessary.

  • IK Inverse Kinematics, Control a chain of bones by specifying the endpoint target (Bones only).

  • LOCKED_TRACK Locked Track, Rotate around the specified (‘locked’) axis to point towards a target.

  • SPLINE_IK Spline IK, Align chain of bones along a curve (Bones only).

  • STRETCH_TO Stretch To, Stretch along Y-Axis to point towards a target.

  • TRACK_TO Track To, Legacy tracking constraint prone to twisting artifacts.

  • ACTION Action, Use transform property of target to look up pose for owner from an Action.

  • ARMATURE Armature, Apply weight-blended transformation from multiple bones like the Armature modifier.

  • CHILD_OF Child Of, Make target the ‘detachable’ parent of owner.

  • FLOOR Floor, Use position (and optionally rotation) of target to define a ‘wall’ or ‘floor’ that the owner can not cross.

  • FOLLOW_PATH Follow Path, Use to animate an object/bone following a path.

  • PIVOT Pivot, Change pivot point for transforms (buggy).

  • RIGID_BODY_JOINT Rigid Body Joint, Use to define a Rigid Body Constraint (for Game Engine use only).

  • SHRINKWRAP Shrinkwrap, Restrict movements to surface of target mesh.
