Elements in Rig Mode


Prototype objects are used for generating rigs. They are created using Rigging Tool and are attached to Joints.


By default, prototype controllers are not visible in the Outliner, To make them visible, enable Show prototype inner objects in the drop-down menu accessed by clicking the icon at the top right corner of the Outliner panel.

When character rig is generated, these prototype objects are used to create point and box controllers, as well as rigid bodies needed for animating the character and making its movement physically accurate.

To rig a character, you need to add a set of prototype objects to every joint of the character skeleton.

Kinds of Prototype Objects

Prototype objects are created in sets. Each set includes:

1. Proto rigid body

The main element of the set. A proto rigid body is attached to the joint (or several joints) and holds all the other objects.

When the rig is generated, a proto rigid body is used for creating a rigid body.

2. Proto box controller

The secondary element that encompasses the joint(s)

When the rig is generated, this object is used for creating a box controller.

Proto point controllers

These three elements are used for creating point controllers when the rig is generated.

3. Main point controller

Placed at the foundation of the main joint. Prototypes for Point Controller Edges connect it to two more point controllers

4. Direction point controller

Placed at the point where the main joint connects with the child joint. Its position is determined by the child joint

5. Additional point controller

Its position can be set manually using the Additional point in Axis group of parameters

Created prototypes can be selected in the Viewport window. Selecting an element in the Viewport will also select it in the Outliner window, where you can adjust its parameters.

You can also use Manipulators to adjust the positions and sizes of the prototype elements; this is not required, but can be useful in some cases.

Proto Union Behavior

This is a dedicated group of parameters for customizing Prototype Objects. It can be accessed through the Object Properties panel, under the Proto union behavior tab.

The mass of the Prototype rigid body.

The width parameter for the prototype rigid body.

If this is enabled, the prototype (and the corresponding elements of the rig) is connected to its parent in a “rigid” way.
For example, a part of a character's body should be bound to its parent: if it moves, other body parts should also move accordingly.
On the other hand, a separate object (like something the character holds in his hand) should not be bound to the parent, even though it is hierarchically connected to the character.

Enabled by default.

If this is enabled, a direction controller is added when a hinge connection is created for the prototype component.

Enabled by default.

This parameter should be enabled (or disabled) to flip the Direction controller.

Direction_controller length
Sets the length of the direction controller.

Should be enabled when you create a second Hinge connection in a row (i.e. when the previous prototype already has a Hinge connection).
