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’
