v3.0.0 has been released

Transition from v2 to v3

Starting from version 3.0.0, the MFCC values have been corrected to be more accurate. Therefore, if you are upgrading from version 2 to version 3, you will need to recalibrate or create a new Profile.

Update

• Improved calculation method for MFCC (to get values closer to commonly used values).
  • Article: https://tips.hecomi.com/entry/2023/03/31/022324 (written in Japanese)
• Added multiple comparison methods for MFCC in Profile (L1 / L2 / CosineSimilarity and Use Standardization).
• Added VRM 1.0 resources to samples.
  • Created using VRoid
• Added a sample that displays UI at runtime to allow editing and calibration of profiles.
• Improved editor performance (by creating MFCC textures with Job + Burst).

Bug Fix

• Fix microphone desynchronization issues #30
• The first parameter set in uLipSyncAnimator does not work. #37

Comparison Method

Previously, L1 without standardization was used.

VRM 1.0

Runtime UI

v2.6.1 has been released!

Bug Fix

• fix Timeline Setup Helper to take clipIn and timescale into account

v2.6.0 has been released!

Update

• Add 10. Runtime Setup example
• Add Timeline Setup Helper
• Add an API to get phoneme names Profile.GetPhonemeNames()

Timeline Setup Helper

Window > uLipSync > Timeline Setup Helper

This tool automatically creates BakedData corresponding to clips registered in AudioTrack and registers them in uLipSync Track.

Runtime Setup

1. Attach uLipSyncBlendShape
2. Register SkinneMeshRenderer there
3. Bind the phoneme name registered in Profile and the corresponding SkinnedMeshRenderer BlendShape with AddBlendShape(string phoneme, string blendShape)
4. Attach uLipSync
5. Register Profile
6. Register the callback for uLipSyncBlendShape there

v2.3.0 has been released

• Performance improvement of Timeline editor #18

v2.2.0 has been released

Update

Update Method has been added to uLipSyncBlendShape #17 thanks to @mkc1370

Update Method can be used to adjust the timing of updating blendshapes with uLipSyncBlendShape. The description of each parameter is as follows.

Method	Timing
LateUpdate	LateUpdate (default)
Update	Update
FixedUpdate	FixedUpdate
LipSyncUpdateEvent	Immediately after receiving LipSyncUpdateEvent
External	Update from an external script (ApplyBlendShapes())

If you have created a script that overrides LateUpdateBlendShapes(), you will need to change it to OnApplyBlendShapes().
