# CA_Spine

![](https://ariserigging.com/wp-content/uploads/2026/05/image-262.png)

Creates a cartoon spine with IK/FK, bendy bones, Bezier ctrls, manual/auto volume, moveable pivots, and more.

Guides:

- **'COG'** - Position at the center of gravity, around the pelvis area.
- **'Base'** - Position at the base of the spine, slightly above the pelvis.
- **'Spine_#'** - Position these guides along the spine, up until below the rib-cage. The number of these guides is determined by the attribute 'IK FK Ctrls Count'.
- **'Chest' **- Position at the bottom of the rib-cage.

Attributes:

1. **'Single Side Guide'** - For some [**Aim Guides**](https://ariserigging.com/docs/elements/guides/), the 'side_vector' (twist) is locked and driven by a single 'side_vector', which keeps the orientation consistent. Uncheck this attribute to unlock them if you need more control over the twist. Re-template is required when changes are made. [**[Video]**](https://youtu.be/-1fpRw6oJME?t=233)
2. **'Ctrls Scale'** - Scale all the node ctrls. Note that the attachments [**'Ctrls Settings'**](https://ariserigging.com/docs/attachments/ctrlssettings/) and [**'CtrlsShape'**](https://ariserigging.com/docs/attachments/ctrlsshape/) will override this.
   *[As of version 1.06.03]*  'Update' button to change the ctrls size without requiring a rebuild. [**[Video]**](https://youtu.be/-1fpRw6oJME?t=31) 
3. **'Clean Transformations'** - If checked, the [**zeroed pose**](https://ariserigging.com/docs/elements/poses/) will be the same as the [**bind pose**](https://ariserigging.com/docs/elements/poses/); if unchecked, when zeroing the ctrls, they will align with a world axis specified in the following two attributes. **[[Video]](https://youtu.be/-1fpRw6oJME?t=61)**
4. **'World Orientation'** - The world axis the ctrls will align with when zeroed. Usually, this attribute's default value is the correct value. **[[Video]](https://youtu.be/-1fpRw6oJME?t=61)**
5. **'World Orient Twist'** - Along with 'World Orientation', defines the ctrls zeroed pose. Usually, the default value of 0 is the correct value. **[[Video]](https://youtu.be/-1fpRw6oJME?t=61)**
6. **'Expose RotateOrder'** - Exposes all the ctrls 'RotateOrder' attribute in the Channel Box. [**[Video]**](https://youtu.be/-1fpRw6oJME?t=149)
7. **'Secondary Ctrls'** - Secondary ctrls are added under some ctrls to help prevent gimbal lock.
   A visibility attribute is added to the parent ctrl. [**[Video]**](https://youtu.be/-1fpRw6oJME?t=157)
8. **'Volume'** - Adds 'Auto Volume' and 'Manual Volume' attributes.
9. **'Movable Pivots'** - Adds a movable pivot to 'cog_ctrl' and 'pelvis_ctrl', similar to the attachment [**'MovablePivot'**](https://ariserigging.com/docs/attachments/movablepivot/).
10. **'IK Ctrls Follow'** - IK ctrls will aim at their next ctrl and move with 'base_ctrl' and 'chest_ctrl'.
11. **'IK FK Ctrls Count'** - The number of middle ctrls between 'base_ctrl' and 'chest_ctrl' for both IK and FK.
12. **'Ribbon Joints'** - The number of skinning joints the spine has besides the 'pelvis_jnt' and 'chest_jnt'. [**[Video]**](https://youtu.be/-1fpRw6oJME?t=198)
13. **'Ribbon Micro Ctrls'** - Create a ctrl for every ribbon skinning joint. [**[Video]**](https://youtu.be/-1fpRw6oJME?t=211)
14. **'Bezier Ctrls'** - Add ctrls that deform the ribbon like a Bezier curve. [**[Video]**](https://youtu.be/-1fpRw6oJME?t=222)
15. **'Bezier Ctrls Offset'** - Position offset of the Bezier ctrls from the joint chain.

Connections:

- **'Root Input'** - Drives the whole node.
- **'Root Output'** - An output at the pelvis joint.
- **'Tip Output'** - An output at the chest joint.
