Houdini 12 Shelf tools Auto Rigs tab

Creates an Auto Rig spine for a biped character.

This tool puts down an Auto Rig Biped Spine node and sets the hook object parameter. This tool is used for building biped characters.

Note

This body part does not use inverse kinematics, therefore does not have bones.

Using Biped Spine

  1. Select the hook object.

    The hook object provides parent transforms to the body part.

    Note

    The most common hook points are highlighted yellow (neck and hip) for easy identification.

  2. Click the Biped Spine tool on the Auto Rigs tab.

    Note

    If you ⇧ Shift + LMB the button you will get a list of different types of biped spines to choose from.

Parameters

Hook Object

The path of the hook object.

Layer

Indicates the order for the parent’s Set Rig. For example, the character placer is set to 0, the spine is set to 1, the arms and legs are set to 2 etc. This prevents the arms from being created or set before the spine when a rig is created or modified.

Set Rig

Display Controls

Makes the controls visible or invisible.

Display Wire

Makes the wire visible or invisible.

Control Scale

Allows you to re-size the controls.

Rigging

The parameters on this tab allow you to translate the center of gravity, hip, lumbar, chest, and neck. This can also be done by translating the controls in the scene view.

Proxy

Show

Shows the bounding geometry or proxy groups of the body part.

Cutting Handles

Hides or shows the cutting handles in wireframe or shaded modes.

The rest of the parameters on this sub-tab allow you to translate, rotate, and scale the proxy cutting controls of the spine. These include: pelvis, hip, lumbar, chest, and neck.
