class bpy.types.SplineIKConstraint(Constraint)

Align ‘n’ bones along a curve

bulge

Factor between volume variation and stretching (in [0, 100], default 0.0)

Type:

float

bulge_max

Maximum volume stretching factor (in [1, 100], default 0.0)

Type:

float

bulge_min

Minimum volume stretching factor (in [0, 1], default 0.0)

Type:

float

bulge_smooth

Strength of volume stretching clamping (in [0, 1], default 0.0)

Type:

float

chain_count

How many bones are included in the chain (in [1, 255], default 0)

Type:

int

joint_bindings

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

Type:

bpy_prop_array[float]

target

Curve that controls this relationship

Type:

Object

use_bulge_max

Use upper limit for volume variation (default False)

Type:

bool

use_bulge_min

Use lower limit for volume variation (default False)

Type:

bool

use_chain_offset

Offset the entire chain relative to the root joint (default False)

Type:

bool

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 (default True)

Type:

bool

use_even_divisions

Ignore the relative lengths of the bones when fitting to the curve (default False)

Type:

bool

use_original_scale

Apply volume preservation over the original scaling (default False)

Type:

bool

xz_scale_mode

Method used for determining the scaling of the X and Z axes of the bones (default 'NONE')

  • NONE None – Don’t scale the X and Z axes.

  • 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:

Literal[‘NONE’, ‘BONE_ORIGINAL’, ‘INVERSE_PRESERVE’, ‘VOLUME_PRESERVE’]

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 (default 'NONE')

  • 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:

Literal[‘NONE’, ‘FIT_CURVE’, ‘BONE_ORIGINAL’]
