base classes — bpy_struct, Constraint

class bpy.types.SplineIKConstraint.SplineIKConstraint(Constraint)

bulge

Factor between volume variation and stretching

Type

float in [0, 100], default 0.0

bulge_max

Maximum volume stretching factor

Type

float in [1, 100], default 0.0

bulge_min

Minimum volume stretching factor

Type

float in [0, 1], default 0.0

bulge_smooth

Strength of volume stretching clamping

Type

float in [0, 1], default 0.0

chain_count

How many bones are included in the chain

Type

int in [1, 255], default 0

joint_bindings

(EXPERIENCED USERS ONLY) The relative positions of the joints along the chain, as percentages

Type

float array of 32 items in [0, 1], default (0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0)

target

Curve that controls this relationship

Type

Object

use_bulge_max

Use upper limit for volume variation

Type

boolean, default False

use_bulge_min

Use lower limit for volume variation

Type

boolean, default False

use_chain_offset

Offset the entire chain relative to the root joint

Type

boolean, default False

use_curve_radius

Average radius of the endpoints is used to tweak the X and Z Scaling of the bones, on top of XZ Scale mode

Type

boolean, default False

use_even_divisions

Ignore the relative lengths of the bones when fitting to the curve

Type

boolean, default False

use_original_scale

Apply volume preservation over the original scaling

Type

boolean, default False

xz_scale_mode

Method used for determining the scaling of the X and Z axes of the bones

  • NONE None, Don’t scale the X and Z axes (Default).

  • BONE_ORIGINAL Bone Original, Use the original scaling of the bones.

  • INVERSE_PRESERVE Inverse Scale, Scale of the X and Z axes is the inverse of the Y-Scale.

  • VOLUME_PRESERVE Volume Preservation, Scale of the X and Z axes are adjusted to preserve the volume of the bones.

Type

enum in [‘NONE’, ‘BONE_ORIGINAL’, ‘INVERSE_PRESERVE’, ‘VOLUME_PRESERVE’], default ‘NONE’

y_scale_mode

Method used for determining the scaling of the Y axis of the bones, on top of the shape and scaling of the curve itself

  • NONE None, Don’t scale in the Y axis.

  • FIT_CURVE Fit Curve, Scale the bones to fit the entire length of the curve.

  • BONE_ORIGINAL Bone Original, Use the original Y scale of the bone.

Type

enum in [‘NONE’, ‘FIT_CURVE’, ‘BONE_ORIGINAL’], default ‘NONE’
