AniKin v1.0.0: The Advanced Workflow Update (IK/FK, Retiming, & Playblast)

We are incredibly excited to announce AniKin v0.5.0, a massive milestone that brings the toolkit up to professional feature parity. This release introduces five brand new, highly-requested advanced workflow modules, alongside a major stabilization pass for AniPose Pro.

🌟 What's New

🔗 AniMatch (IK/FK Snap & Match)

A robust, production-grade IK/FK matching engine.

• Auto-Detect Heuristics: Automatically scans your rig for _IK_CTRL and _FK_CTRL naming conventions to pair limbs without manual setup.
• No-Flip Math: Uses constraint-based rotational transfer to completely avoid the dreaded 360° gimbal flip bug.
• Pole Vector Solving: Mathematically calculates perfect pole vector placement using mid-limb perpendicular projections.
• Bake-Match Range: Right-click to bake the match across your entire selected timeline range.

📍 AniBake v2 (Temp-Space & Micro-Pivots)

Smart Bake has evolved into a full world-space protection tool.

• Temp-Space Unlock/Relock: Select multiple extremities (like both hands), click Unlock to freeze them in world-space, freely edit the torso/parents, and hit Relock to bake the local offsets back.
• Dynamic Micro-Pivots: Drop a temporary red locator, rotate/position it to act as a custom pivot point for your controls, and commit the orbit motion directly to your curves.

⏱️ AniRetime (Scale & Integer Snapping)

Scale curves without breaking your timeline.

• Collision-Aware Snapping: Native Maya scaling causes fractional keyframes (e.g., frame 12.4). AniRetime's new snapping logic rounds keys to whole frames while actively preventing overlapping keys from collapsing/merging and destroying your data.
• Quick Retime: 1-click x0.5 (double speed) and x2.0 (half speed) scaling from the start of your selection.

🎬 AniBlast (Advanced Playblaster)

A 1-click, professional output generator.

• HUD Burn-ins: Automatically injects Current Frame, Camera Focal Length, Scene Name, and Animator Name into the viewport.
• Smart HUD Allocation: Dynamically searches for free HUD blocks so it never collides with your native Maya viewport overlays.
• ffmpeg Integration: Captures an image sequence and silently hands it off to ffmpeg in the background to spit out a crisp, H.264 MP4 file.

☄️ AniTrail (Editable Motion Trails)

• Replaces the old AniMotion module with a proper wrapper around Maya's native motionTrail node, meaning you can click and drag the trajectory vertices directly in the viewport.
• Auto-cleans up all trail nodes on Scene Save so your outliner stays pristine.

🎨 UI & UX Improvements

• Icon Pack Upgrade: Downloaded and recolored brand new Tabler/Lucide icons specifically for the new modules (Orange for Retime, Blue for Playblast, Green for Match).
• Merged Toggles: Combined Lock/Unlock and Play/Pause into dynamic, state-aware toggle buttons to save toolbar real-estate.

🐛 Bug Fixes & Stability

• AniPose Pro Crash Fix: Resolved a critical bug where Maya's C++ garbage collector would destroy the Pose UI window, causing a fatal crash. Widgets are now properly parented to the Maya Main Window.
• Undo Queue Flooding: Dragging the Tween/Ease sliders no longer floods your undo queue with hundreds of tiny chunks. It now packages the entire drag action into a single, atomic Undo step.
• HUD Collisions: Fixed a RuntimeError in AniBlast where the custom HUD would fail to render if the user already had native Maya HUDs enabled.

Installation:
Simply run drag_drop_install.py in your Maya viewport, or execute:
import anikin; anikin.launch()
