ZenDyn Changelog

2.0.1

Improved Live Link compatibility with ARKit and MetaHuman Animator performances while preserving lip-sync.
Added support for captured MetaHuman Animator head and neck movement, both standalone and with ZenBlink.
Kept procedural facial animation, including micro-saccades, active during Sequencer playback.
Improved project startup reliability, including C++ projects.
Improved automatic recovery when the shared ZenBlink animation setup is refreshed.
Preserved emotion transitions, blink timing, regional smoothing and facial Dynamics when animation sections end or ZenDyn’s animation setup is briefly recreated.

ZenDyn 2 is a major rebuild of the plugin for Unreal Engine 5.6, 5.7, and 5.8.

Native C++ ZenDyn Actor Component and interface with streamlined toolbar and manual attachment workflows.
Independent Dynamics, Magic, Weight, and Smoothing for Brows, Nose, Cheeks, Mouth, Jaw, and Eyes.
Direct Emotion Pose selection plus procedural emotion variation, facial idle, breathing, eye movement, micro-saccades, and blinking.
ZenDyn Presets, Sequencer-keyable controls, and the Bake ZenDyn Animation command.
Automatic ZenBlink integration for combined facial animation and Dynamics.

Facial blending that protects incoming dialogue, lip-sync, and eye animation in Blend by Weight and Override modes.
Smooth emotion transitions and deterministic procedural animation with safe default random seeds.
Natural regional secondary motion with per-region Strength, Damping, Stiffness, and Smoothing.
Focused Details-panel sections, editor preview, empty-track facial baking, and packaged runtime behavior.
Consistent facial Dynamics across all supported engine versions.

The native component replaces the ZenDyn 1 World Actor and Blueprint-led setup.
Independent regional settings replace the ZenDyn 1 Global/Groups dynamics selector.
Normalized and 0-3 controls use clear percentage ranges; incoming eye animation uses Eye Mode: Input Pose.
Direct baking to stock MetaHuman Control Rigs is considered experimental and unsupported; bake to an animation sequence first.

ZenDyn 1 projects require a manual migration. See Upgrading from ZenDyn 1 to ZenDyn 2.
