Live Studio Virgo Extension

Change history for jp.lilium.livestudio.virgo.

[0.25.1] - 2026-07-20​

Added

  • THIRD_PARTY_NOTICES.md documents the third-party components bundled under Tools~/VirgoMotionFusion/ (MediaPipe and its models, MediaPipe Unity Plugin, Protocol Buffers, UniVRM, Newtonsoft.Json, Bouncy Castle, Final IK and the Unity packages), which this package shipped without attribution until now.

Changed

  • FusionApp now always passes the window preference explicitly: -hidewindow or the new -showwindow. Fusion starts hidden (tray-only) by default, so fusionHideWindow: false alone would otherwise launch a Fusion that hides itself anyway.

Removed

  • The bundled Fusion build no longer ships the six AR Foundation Remote assemblies or MCPForUnity.Runtime.dll. Both are editor-only development tools that a Player build never references, and AR Foundation Remote is a paid Asset Store asset that was not meant to travel inside this openly distributed package. The build script drops them from Managed/ and from ScriptingAssemblies.json.

[0.25.0] - 2026-07-17​

Added

  • VirgoMotionSource.ResyncTiming: an exposed function that clears the frame buffer and the frame offset so the next Update re-locks onto the sender's numbering. Sender (Fusion) and receiver (Studio) number frames from their own wall clocks, so a frame offset bridges the two; this also recovers from long stalls or clock jumps.

Changed

  • Fusion now ships as a Player (windowed) build that can embed the capture scene, so batch mode alone no longer identifies it: FusionApp always appends the -fusion-child / -hidewindow launch arguments and FusionQuitSignalListener gates on the marker (batch mode is still accepted for older headless builds).
  • BuildPostProcessor bundles Tools only for StandaloneWindows64, so iOS and Capture builds no longer get Tools copied next to their output.

Fixed

  • The avatar no longer freezes after Fusion restarts. The sender's frame numbering drops to low values on restart while the buffer's frameCount only grows, pinning playback to a stale frame; VirgoMotionSource now auto-resyncs by clearing the frame buffer when the received numbering jumps far backwards. Frame-gap warnings are also limited to gaps wider than the interpolation search span.
  • Studio now retries the buildavatar POST to Fusion until it lands, so a Fusion that starts after Studio still receives the avatar skeleton (previously the one-shot POST failed and the avatar had to be re-selected). The transient connection failure is logged once as a warning instead of an error, so launching Studio without Fusion no longer spams the console.

[0.24.3] - 2026-07-09​

Changed

  • VirgoMotionSource resync and received-frame-gap messages are now plain logs instead of warnings; they occur under normal timing jitter, so demoting them removes recurring console noise.

Fixed

  • The pose frame's root valid byte now carries separate body (MediaPipe) and face (ARKit) tracking bits, driving the asymmetric avatar-visibility gate in jp.lilium.livestudio so the meshes no longer blink as the subject leaves the capture frustum.

[0.24.2] - 2026-07-05​

Changed

  • VirgoMotionSource is now anchored to the capture-camera reference point on warp: on WarpTo the avatar is placed at the mark and the source transform is placed at mark + up * height + forward * distance, rotated 180° on Y so +Z faces the subject, pinning the shooting camera (cam0) there. With the real-world camera height / distance set, the avatar lands on the mark. ResetCamera is now camera-relative.
  • The default _cameraDistance / _cameraHeight on VirgoMotionSource are now 0.7 m / 1.3 m.

Fixed

  • Incoming pose frames are now sampled with gap tolerance: the interpolation buffer searches nearby frames instead of requiring exact frame numbers, absorbing the periodic dropped frame caused by wall-clock quantization as well as occasional UDP drops. This removes the recurring motion spikes / stutter seen on the Capture→Fusion→Studio path.
  • Capture reset now zeroes yaw correctly, so re-centering no longer leaves the avatar facing a residual direction.

[0.23.5] - 2026-06-22​

Added

  • The Readme inspector now verifies the project settings required for gamepad background input (Player Settings "Run In Background" and Input System "Background Behavior = Ignore Focus"). When either is disabled it shows a warning with a one-click button that enables both, so gamepad input keeps working in builds while the app is not the foreground window.

[0.23.0] - 2026-06-21​

Changed

  • VirgoMotionSource now interpolates between the two nearest received 60fps frames inside Update (with a configurable _delaySeconds lead so the interpolation target is already buffered), so the avatar advances smoothly under variable render fps and SpringBones no longer shiver on held frames. An optional anchor transform is used as the placement basis, letting the source live inside an additively loaded set.
  • VRCFTAvatar expression is now routed through ExpressionResolver.

Fixed

  • ResetCamera now reads the capture-camera channel (device/ARKit yaw) instead of the pose-driven avatar root, which latched onto a jittery pose snapshot and made every reset land slightly differently; repeated resets are now stable. A new _cameraHeight field (default 1.5 m) lifts the virtual camera to eye level instead of dropping it to the floor.

[0.22.0] - 2026-06-14​

Added

  • The AnimationFrameData wire frame now carries a per-bone tracking presence array (bonePresences, 0..1), bridged into HumanoidPoseData.bonePresences so the Studio avatar can blend the mocap pose with its own animation per bone. AnimationSystem.MakeAnimationFrameData currently fills every tracked bone with presence 1 (full-body tracking); the synthesis side can lower individual bones to let their animation flow through.

Changed

  • The AnimationFrameData wire frame now carries two capture-camera channels (cameras[2], one CameraData each) instead of a single camera, so the worldA / worldB cameras are bridged independently into the avatar pipeline.
  • Wire format change: AnimationFrameData grew by the per-bone presence array and the second capture-camera channel, so its serialized size changed. The Fusion app and Studio validate frames by exact struct size, so the Fusion executable must be rebuilt for Studio to accept frames again (an older Fusion build is rejected as an invalid size).

[0.21.2] - 2026-06-11​

Changed

  • FusionApp now guarantees the Fusion process is terminated on shutdown: when the PID-keyed quit signal cannot be delivered (startup race or an orphan from a previous run), it hard-kills the process instead of leaving it lingering. Studio no longer blocks waiting for Fusion to exit.
  • BuildStudioApp derives the build output folder and exe name from the project folder (VirgoMotionStudio / VirgoMotionStudioVRC), dropping the dedicated VRC build entry point and profile path. In batchmode it opens the first build scene to avoid lilToon recompiling all shader variants.

[0.21.0] - 2026-06-08​

Changed

  • The Fusion process is now hosted by a FusionApp component instead of the static FusionAppHost, making Fusion hosting configurable per scene.

[0.20.11] - 2026-06-03​

Added

  • Fusion is now asked to quit gracefully on Studio shutdown via a PID-keyed quit signal (FusionQuitSignalListener), so the windowless Fusion process saves its state instead of being hard-killed.

Changed

  • Studio no longer blocks on Fusion's exit when stopping it; the quit signal is sent and Studio returns immediately.

Fixed

  • The Readme inspector buttons are now clickable even when LiveStudioVirgo is consumed as an immutable git/registry dependency.

[0.20.10] - 2026-06-02​

Added

  • The capture UDP ports are now allowed through Windows Firewall automatically before Fusion launches (one-time UAC prompt). New registerFusionFirewallRule / fusionCapturePorts project settings control this.
  • "Allow Capture Ports through Firewall" button in the Readme inspector for recovering when motion is not received, plus a description line above the optional packages list.

Changed

  • The "Allow Capture Ports through Firewall" action now reports its result (already allowed / added / failed) via a dialog instead of silently doing nothing when the rule already exists.

[0.20.9] - 2026-06-02​

Added

  • VirgoMotionSource reception indicator showing the live UDP packet reception state.
  • Optional package installer with Install buttons in the Readme inspector.

Fixed

  • Replaced the UDP receive thread busy-wait with Socket.Poll to reduce idle CPU usage.

[0.19.1] - 2026-05-07​

Added

  • Initial release. Imported from the parent VirgoMotion repository as jp.lilium.livestudio.virgo. Provides the VirgoMotion-specific adapter layer (UDP VirgoMotionSource, Fusion REST FusionRequestSystem, AnimationFrameBridge, Build / Tools menu) on top of jp.lilium.livestudio.
