CHARACTER RIGGING
KineFX powered by APEX brings a truly procedural approach to rigging. By simply tagging joints, you can assign rig components that are ready to animate. This creates a high level workflow that doesn't require a deeper understanding of APEX while more advanced riggers can create custom tools using the new APEX script.
The APEX Animation and Rigging tools is released in BETA with Houdini 20.5
Tags
Tags allow you to quickly identify parts of a rig that will then be assigned to rig components.
APEX Script
For custom components, use APEX script to lay out APEX graphs with a Python-like syntax.
Embedded CFX
Feathers, fur, wrinkles and ML can now be part of your rig while it is being animated.
Tags
Tags allow you to quickly identify parts of a rig that will be assigned to rig components. You can identify a left arm and a right arm, then set up IK for both arms by referencing the tags. Different rigs that share the same tags can have their rigs built procedurally.
Procedural Rigs
All of these creatures share the same tags/components.
Rig Tags
Tagging joints prepares them for the Rig components.
Rig Components
Pre-built rig components are available from the APEX Autorig Component and APEX Rigscript Component SOPs, including components for full body IK, multi-bone IK, IK/FK blending, reverse foot, spline, blend shapes, delta mush, look at constraints, and mapped constraints.
Procedural Transfer
Components can work with a variety of different rigs based on their tags.
Components UX
This panel gives you access to components and the ability to link them to tags.
Gears
The rig components also work with mechanical systems such as this steam engine.
APEX Script
Custom rig components can now be built using APEX Rigscript. For instance the animation of the legs on these spiders is automated using one of these scripts.
APEX Script is similar to Python but acts as a code interface for the APEX graphs. Code snippets can now build the graphs for you.
Embedded CFX
Feathers, fur, and wrinkles can now be animated along with your rig. This provides more control for the animator as these character FX become internal to the animation workflow. Even Machine Learning can play a role in providing animators with immediate feedback.
Wrinkle Deform
This new solver can add a wrinkle pass over soft bodies or cloth.
Rig Wrinkle
Wrinkles can be added into the rig itself in support of animation.
