Bone Info Node¶

The Bone Info node retrieves transform information for a bone from an armature object.

This can be used to drive Geometry Nodes with an armature, create procedural rigging effects, or implement custom armature deformation using vertex group attributes.

Note

A dependency cycle can occur if the Bone Info node uses one bone and another bone in the same armature in turn depends on the modified object, for example using a Geometry Attribute Constraint. Inside an armature each bone can be referenced individually, but the geometry modifier node can only add a dependency on the entire armature. This is because the bone name is a generic string that does not generally point to a single bone.

輸入¶

Armature

Armature object to get bone poses from.

Bone Name

Name of the bone to evaluate.

If the specified bone does not exist, a warning is displayed unless the Exists output is used.

屬性¶

Transform Space

The space in which pose transforms are defined.

Original:: Output the pose and rest pose relative to the armature object origin.
Relative:: Bring the pose and rest pose into the modified object's space.

輸出¶

Pose: Evaluated final transform of the bone.
Local Pose: Difference between the pose and rest pose, relative to the parent bone. Not affected by the transform space.
Transform Pose: Matrix representing the bone's location, rotation, and scale properties. Not affected by the transform space.
Rest Pose: Original transform of the bone as defined in edit mode.
Rest Length: Original length of the bone.
Exists: Whether the specified bone exists in the armature.
