base classes — bpy_struct, Constraint

class bpy.types.KinematicConstraint(Constraint)

Inverse Kinematics

chain_count

How many bones are included in the IK effect - 0 uses all bones

Type :int in [0, 255], default 0

distance

Radius of limiting sphere

Type :float in [0, 100], default 0.0

ik_type

Type :enum in [‘COPY_POSE’, ‘DISTANCE’], default ‘COPY_POSE’

iterations

Maximum number of solving iterations

Type :int in [1, 10000], default 0

limit_mode

Distances in relation to sphere of influence to allow

• LIMITDIST_INSIDE Inside, The object is constrained inside a virtual sphere around the target object, with a radius defined by the limit distance.
• LIMITDIST_OUTSIDE Outside, The object is constrained outside a virtual sphere around the target object, with a radius defined by the limit distance.
• LIMITDIST_ONSURFACE On Surface, The object is constrained on the surface of a virtual sphere around the target object, with a radius defined by the limit distance.
