INTERFACE

The Rigger interface is designed in such a way that the necessary tools are at hand. FK, IK and IK Spline are 3 basic methods for skeleton animation. To provide the necessary functionality for the rig, these techniques can be combined.

To the right of each element is a button for setting parameters.

Under the settings buttons there are additional tools for rigging: the orientation of the bones, the tool for mass renaming and the button for skinning.

In the very right part of the plugin is an icon for resetting the pose of the character, the finalise rig button, a mirror joint button and a Create Skin Helper button. When you right-click on any icon, a menu with additional tools appears.

At the top of the plugin is a menu for quick access to the necessary elements (Create, Select, Cleanup, Skeleton, Constrain, Skin, Mesh, Help).

FORWARD KINEMATICS

To create the joint, click ‘FK’ and draw a bone. Move it to the desired position relative to the model and press ‘FK’ again. Rigger automatically marks this bone as a controller, saves the initial pose and adds the ‘Rotate Order’ attribute.

FK Settings

In the FK settings, you can choose one of 3 forward kinematic modes: Classic, Shape and Bone. In Bone mode (default), the bone is marked as a controller and is used later for animation. The color of the controller is determined using the ‘Color’ slider. Shape mode allows you to add a Shape Node to any object. When creating a shape, the ‘Shapes’ attribute is created on the main control (‘rig_ctrl’), which turns on and off the display of the shape curves. Only 5 controller shapes: Square, Circle, Cube, Sphere and Cross. Shape diameter is controlled using the ‘Size’ attribute. In ‘Classic’ mode, an object of type NURBS Curve is created, placed in a group. Depending on the ‘Constraint’ setting, a ‘Parent’, ‘Point’, ‘Orient’ or ‘Scale’ constraint is created for the selected object. For the Classic mode, additional options are also available: ‘World Oriented’ (the controller is oriented to world coordinates), ‘Display Handle’ (creates a minimalistic controller with high priority for selection), ‘Animatable Pivot’ (the bone moves under the controller and attributes are added for animation of the center of rotation), ‘Parent Joint’ (the bone moves under the controller) and ‘Hide Joint’. To create an FK for the entire bone hierarchy, enable the ‘On Hierarchy’ mode.

Lock attribute

Lock Rotate, Translate and Scale attributes.

Unlock attribute

Unlock Rotate, Translate and Scale attributes.

Add Animatable Pivot Attributes

Adds attributes for the ability to change and animate the center of rotation (only works with the ‘Classic’ FK).

Remove Animatable Pivot Attributes

Remove center of rotation attributes.

Squash and stretch constraint

Preservation of volume in tension. To create ‘Squash and Stretch Constraint’, select the bone, right-click on the FK icon and select ‘Squash and Stretch Constraint’.

Volume constraint

Allows you to create a wavy effect for a whole chain of bones. The effect is controlled with the help of the attributes ‘Volume’, ‘Position’ and ‘Fallof’ on the root bone.

Make Joint Hierarchy Dynamic

Create nHair dynamics on joint hierarchy. An ‘Intensity’ attribute will be created on the top controller. You can control other attributes of the dynamics with the hairSystem node. If you want a collision on object then select the object mesh and create a passive collider.

Duplicate Joint

The command duplicates two joints connected to one bone.

Freeze Joint

Allows you to set zero values of the translation attributes on the joints (only works with individual joints).

Mirror Joints

Duplicates the current joint chain across the specified plane. The command works with multiple selection, skin helpers and volume savers.

Delete Shapes

Deletes object’s shape node.

Delete FK

To delete the FK controller, select the bone, right-click on the FK icon and select ‘Delete FK’.

INVERSE KINEMATICS

To create an IK, select one or more bones and click ‘IK’. To switch the kinematics, select the bone or IK Handle and press ‘Character Menu > IK / FK’ or press right mouse button on the joint and choose ‘Enable ikHandle’. You can also change the ‘Ik Blend’ attribute by selecting the IK Handle. Depending on the kinematics, the color of the bones changes (blue by default for FK, yellow for IK). Select IK Handle and press ‘T’. In this way, you can quickly control the attributes ‘Twist’ and ‘Pole Vector’ that are responsible for the rotation.

IK Settings

In the IK settings, you can enable ‘Auto Stretch’. The attribute ‘Limit Length’ and ‘Auto Stretch’ is added to IK Handle. With ‘Auto Stretch’ enabled, the length of the IK chain is determined by the distance between the root bone and IK Handle. ‘Limit Length’ does not allow the IK chain to be shorter than its original length (suitable for arms and legs). The ‘Save Volume’ option automatically creates a ‘Squash and Stretch Constraint’ for the IK chain, allowing you to save the volume when compressing and stretching. On the ‘Color Settings’ tab, you can change the color of the IK and FK modes.

Create IK for Each Joint Selected

Allows you to create an IK for all selected bones.

Make IK Stretchy

Adds the ‘Limit Length’ and ‘Auto Stretch’ attributes to the IK Handle, allowing you to stretch the IK chain while preserving the volume.

Connect to IK / FK

Associates the selected object with the IK Handle. Now you can switch kinematics without selecting IK Handle.

Delete IK

To remove an IK, select the bone, right-click on the IK icon and select ‘Delete IK’.

IK SPLINE

To create an IK Spline, select one or more bones and click ‘IK Spline’. The original bone will be divided into seven parts and two FK controllers will be added to control the orientation of the IK Spline. When IK Spline is created on a bone with an existing IK, the source bone will not be changed and will control the orientation of the IK Spline.

IK Spline Settings

In the IK Spline settings, you can change the number of bones that will be used in IK Spline. The ‘Auto Stretch’ and ‘Save Volume’ attributes are similar to the settings in the IK settings window and are responsible for the automatic compression and stretching of the IK Spline chain. On the ‘Color Settings’ tab, you can change the bone color of IK Spline, the color of the FK mode. The ‘Create FK Controllers’ attribute allows you to automatically create Classic FK controls for IK Spline. The Color attribute changes the color of the controllers. Shape: the shape of the controls. Size: size of controls. Animatable Pivot: create controls with an animated rotation center. Display Handle: Create minimalistic controllers with high selection priority.

Make IK Stretchy

Adds the attributes ‘Limit Length’ and ‘Auto Stretch’ to the IK Spline Handle, allowing you to stretch the IK Spline chain while maintaining volume.

Add Middle Controller

Adds an additional FK controller to change the central shape of the IK Spline.

Delete Middle Controller

Removes the middle controller from IK Spline.

Bind curve

Binds an IK Spline curve to bind joints.

Unbind curve

Detaches the IK Spline curve from the bind joints, allowing you to change their position and center of rotation.

Rebuild curve

Reduce or increase the complexity of a Spline IK curve. Try different values to find the right type of deformation.

Delete IK Spline

To remove IK Spline, select the bone, right-click on the IK Spline icon and select ‘Delete IK Spline’.

TOOLS

Orient Joint

If nothing is selected, clicking on the ‘Orient Joint’ icon opens the orientation settings window. If a bone is selected, then the bone is oriented, in accordance with the parameters of the Orient Joint window.

When the ‘Orient Joint to World’ option is turned on, all bones are oriented in accordance with the world axes. ‘Primary Axis’ allows you to specify the primary local axis for the bone. This is the axis that determines the direction of the bone. ‘Secondary Axis’ allows you to specify which axis will be used as the secondary orientation of the bone. The ‘Reverse’ option inverts the World Axis. When the ‘Hierarchy’ option is turned on, all the bones in the selected bone hierarchy are oriented. The ‘+’ and ‘-‘ buttons let you fine tune the orientation on X. The ‘Toggle Axis’ button turns on and off the display of the local axes of the hierarchy of bones. The last bone in the hierarchy is automatically oriented in accordance with the selected parameters.

Split Joint

‘Split Joint’ allows you to split a bone into several bones. The number of divisions can be changed in the Split Joint Settings window.
