GeometryAttributeConstraint(Constraint)

base classes — bpy_struct, Constraint

class bpy.types.GeometryAttributeConstraint(Constraint)

Create a constraint-based relationship with an attribute from geometry

apply_target_transform

Apply the target object’s world transform on top of the attribute’s transform

Type:

boolean, default False

attribute_name

Name of the attribute to retrieve the transform from

Type:

string, default “”, (never None)

data_type

Select data type of attribute

  • VECTOR Vector – Vector data type, affects position.

  • QUATERNION Quaternion – Quaternion data type, affects rotation.

  • FLOAT4X4 4x4 Matrix – 4x4 Matrix data type, affects transform.

Type:

enum in ['VECTOR', 'QUATERNION', 'FLOAT4X4'], default "'VECTOR'"

domain

Attribute domain

Type:

enum in ['POINT', 'EDGE', 'FACE', 'FACE_CORNER', 'CURVE', 'INSTANCE'], default "'POINT'"

mix_loc

Mix Location

Type:

boolean, default False

mix_mode

Specify how the copied and existing transformations are combined

  • REPLACE Replace – Replace the original transformation with the transform from the attribute.

  • BEFORE_FULL Before Original (Full) – Apply copied transformation before original, using simple matrix multiplication as if the constraint target is a parent in Full Inherit Scale mode. Will create shear when combining rotation and non-uniform scale..

  • BEFORE_SPLIT Before Original (Split Channels) – Apply copied transformation before original, handling location, rotation and scale separately, similar to a sequence of three Copy constraints.

  • AFTER_FULL After Original (Full) – Apply copied transformation after original, using simple matrix multiplication as if the constraint target is a child in Full Inherit Scale mode. Will create shear when combining rotation and non-uniform scale..

  • AFTER_SPLIT After Original (Split Channels) – Apply copied transformation after original, handling location, rotation and scale separately, similar to a sequence of three Copy constraints.

Type:

enum in ['REPLACE', 'BEFORE_FULL', 'BEFORE_SPLIT', 'AFTER_FULL', 'AFTER_SPLIT'], default "'REPLACE'"

mix_rot

Mix Rotation

Type:

boolean, default False

mix_scl

Mix Scale

Type:

boolean, default False

sample_index

Sample Index

Type:

int in [0, inf], default 0

target

Target geometry object

Type:

Object
