Fixes:

• Fix TreeView was incompatible with Unity 6.5.

A new version of Blendshape Viewer has been released.

This update introduces a bunch of optimizations to make the UI faster on avatars with a large number of blendshapes. The UI is also localized into multiple languages.

In addition, pressing the ALT key will now show the original picture without the blendshape applied so that you can better pinpoint the differences.

I am releasing Transfer Assistant. This tool will assist you when you want to use the .unitypackage export function to transfer assets from one project to another project, while stripping assets that you deem unnecessary.

This tool will deliberately ignore some asset references, keeping only assets that you actively need.

If an unexpected asset is being included in the export, the Transfer Assistant user interface can help you locate which object or component depends on it.

The intended use for this tool is to export an avatar project file between different games.

🗒️ Open documentation

A new product has been published: Vixxy is a user-accessible interface to toggle or trigger effects on avatars in Basis Framework projects.

It is primarily intended to be used through the Unity inspector directly by non-programmer users.

Effects may be triggered based on the menu, voice, various measurements on the avatar, face tracking, or inputs received from external hardware and software.

It can toggle objects ON and OFF, change shader material settings, blendshapes, textures inside materials, and the text inside TextMeshPro components.

🗒️ Open documentation

A language selector has been added to the Recalculate Normals and Generate Twist Bones components, in Japanese.

All Prefabulous Universal components now have a clickable help URL in the inspector.

Components from Prefabulous Universal will now run with NDMF 1.8 when building the avatar for non-VRChat platforms and apps such as Resonite.

• Generate Twist Bones will now generate Unity Constraints instead of VRC Constraints when targeting a non-VRChat platform.

A language selector has been added to Skinned Mesh Constraint Builder:

• Add language selector for French, Japanese, Korean, Simplified Chinese, Traditional Chinese.

In Edit Mode, hide objects that are hidden by the visibility icon in the scene hierarchy tab.

Fix object change events should no longer trigger in Play Mode, which was causing errors in the logs.

• Fix thumbnail size setting now applies properly when the value is changed.
  • Previously, it may have been applying an old value for the setting.

The above changes have been contributed by mekanyanko (めかにゃんこ).

⚙️ Skinned Mesh Constraint Builder V1.2.1​

• Make VRCSDK compatibility more future-proof.
  • Internal method is VRCConstraintBase.GetPerSourcePositionOffsets() no longer invoked.

Chillaxins V1.2.0​

• Improve compatibility with Basis Framework avatar builds non-Windows OS.

• Fix compatibility with VRCSDK 3.10 where VRCConstraintBase.GetPerSourcePositionOffsets() is no longer public.
  • Thanks to @JLChnToZ for reporting this issue (#2).
• Improve component startup time when hiding the component icon in the scene.

HVR Basis Face Tracking has been updated.

It should work better with ARKit avatars, as we were not requesting some face tracking traits correctly, so VRCFaceTracking would not send them to us. No avatar reupload is needed.

This update includes some performance improvements and some code preparation for future use by HVR Basis AvatarOptimizer, so that avatar optimization tools may detect which blendshapes should not be removed from the mesh.

Backend changes​

Avoid string comparisons in HVR addresses​

• Reduce the number of string comparisons by using int addresses instead of string addresses.
• Addresses are mapped to int equivalents as early as possible.
• Modify AcquisitionService and all scripts that depend on it to use int addresses.
• Add HelpUrls to user-facing HVR behaviours.

Try to fix combined face tracking were not requested​

• Some of the face tracking parameters that were needed by the default face tracking templates were not requested from VRCFaceTracking.
• Update the JSON file (for older versions of VRCFaceTracking) and the OSCQuery response to match.
• Fix UnifiedExpressions-Advanced-Strict incorrectly references addresses without the v2 prefix.

Expose functions for HVR Basis AvatarOptimizer​

• Expose public functions on BlendshapeActuation and AutomaticFaceTracking for future use by HVR Basis AvatarOptimizer.

Lightbox Viewer has been updated to support URP projects.

Lightbox Viewer is now compatible with the following render pipeline configurations:

• BIRP Light Probes.
• BIRP VRCLightVolumes by RED_SIM.
• URP Adaptive Probe Volumes.
• URP Light Probes.

Features:

• Detect and support URP projects. When the current project uses URP:
  • Don't suggest installing the Post-Processing V2 package.
  • Never switch to VRCLightVolumes, even if that package is installed in the project.
  • Switch to a different scene based on whether the Quality settings use Light Probes instead of Adaptive Probe Volumes.
  • Detect when Quality settings change, and switch between the Light Probes scene and the Adaptive Probe Volumes scene accordingly.

Changes:

• Attempt an optimization that removes the need for copying the texture from the GPU to the CPU.
• Change Edit mode strategy for performance:
  • Previously, Edit Mode was copying the avatar every frame, so that we don't accidentally cause the avatar to be modified.
  • This change now copies the avatar to a hidden GameObject in the hierarchy and marked non-saved, if the reference to the Object To View does not change.
  • Use object change events to detect when anything changes in the scene. If there is any change that pertains to a non-transform, we destroy the copied object and create a new one.
  • This copied object is moved 10_000 units downwards between render cycles.
  • Don't disable the original avatar between render cycles, because enabling the avatar is slow.
  • In the copy, remove the Animators, because they take time to bind and we don't need them.

Fixes:

• Try to fix an issue where the depth was affecting how the view was rendered in a Unity 6.2 Basis project.

HVR Basis Face Tracking has been migrated to the new Basis networking system.

Instructions for previous Face Tracking avatar users:

• If you have previously used Face Tracking in Basis, do the following:

• Remove all components that were part of the previous Face Tracking instructions. That includes:

  • Remove the Feature Networking component
  • Remove the HVR Avatar Comms component
  • Remove the Eye Tracking Bone Actuation component
  • Remove the Blendshape Actuation component
  • Remove the OSC Acquisition component
  • Remove the Acquisition Service component

• To install the new Face Tracking, do the following:

  • Create a new GameObject inside your avatar. Give it a name of your choice, like FaceTracking.
  • Add the Automatic Face Tracking component.
  • In the inspector of the Automatic Face Tracking component, press the "Create VRCFaceTracking JSON file" button.
  • You will need to do this even if you have used previous versions of Face Tracking in Basis

The new face tracking has been modified to work with the Steam version of VRCFaceTracking (it now has OSCQuery), but it should also work with old versions of VRCFaceTracking that were not installed from Steam.

Backend changes​

Migrate face tracking to newest Basis networking​

• Migrate to newer Basis avatar networking systems:
  • Remove GUID-based networking identifiers, which was a remnant of the previous networking system where BasisAvatarMonoBehaviour did not exist and all packets had to be routed manually to their destination components.
  • Migrate networking to the new BasisAvatarMonoBehaviour networking system, which handles packet routing on its own by transmitting packets based on the component rather than based on the avatar.
• Add Automatic Face Tracking component:
  • The Automatic Face Tracking component is now the entry point to adding HVR face tracking capabilities to the avatar.
  • This component automatically detects all SkinnedMeshRenderer components on the avatar that have ARKit or Unified Expressions blendshapes on it.
  • By default, this component uses the basic face tracking definition files that are bundled with the application, but this can be either overridden by the user or supplemented.
    • Due to this, the face tracking assets are now addressables.
  • This components automatically starts an OSC service on the wearer.
• Improve the handling of face tracking data:
  • Add Address Overrides to the actuation definition file, so that we can define default values for the eyelids.
  • Work towards the mutualization of the interpolation of addresses between Eye Tracking and Face Tracking.
  • Actuators now introspect which blendshapes actually exist on the target renderers, and will no longer try to network any actuator that has no blendshape associated with it.
  • Add more debugging in the blendshape actuation definition file editor.
  • Fix TongueRoll actuator was targeting the wrong blendshape.
• Move the package to dev.hai-vr.basis.comms/

Change VRCFaceTracking setup process​

• In the Automatic Face Tracking component, the user now presses a button to create the face tracking JSON file used by VRCFaceTracking.
• We want to ensure we overwrite any previous version of face tracking that may have already been installed by previous users of the previous system, so we're changing the dummy avatar ID to a different one. That way, we're sure this is really the file that will be loaded by VRCFaceTracking.

Fix always update local eye angles​

• Update local eye angles, even if no address has changed.
• This should fix an issue where the eyes were always looking forward.

Add a fake OSCQuery service to cope with the Steam version of VRCFaceTracking​

• The Steam Version of VRCFaceTracking 5.3.2.0 does not accept /avatar/change events, it relies only on OSCQuery for initialization.
• We now impersonate the OSCQuery service by doing the following:
  • A) Opens an HTTP service on a random port:
    • When queried for any URL that ends with /avatar, it replies with a pre-determined message (check out response-avtr.json).
    • When queried for any other URL, it replies with another pre-determined message (check out response.json).
  • B) Advertises that port as a service on mDNS as _oscjson._tcp with the instance name VRChat-Client-XXXXXX where XXXXXX is a random number between 100000 and 999999.
  • C) Queries for _oscjson._tcp once when the service starts.
  • A and B are sufficient for VRCFaceTracking to detect our program if the OsushiQuery service is already running when VRCFaceTracking starts.
  • C is needed to handle the case where VRCFaceTracking is already running before our program starts the OsushiQuery service.
  • The HTTP service completely violates the OSCQuery protocol and is not intended to be read by any other program other than VRCFaceTracking.
• The JSON file in the users' directory is still needed to function properly.
• This also means that the application requests a pre-determined list of parameters from VRCFaceTracking, as opposed to the JSON file which could previously be updated separately.
• Add a MeaMod.DNS package as instructed by dooly.

Update acquisition server to accept VRCFaceTracking being initialized from OSCQuery​

• Since VRCFaceTracking is now being initialized from OSCQuery, we can't use the address that don't start with "/avatar/parameters" like we used to.
• Rectify the paths in the JSON file to match the OSCQuery paths.
• Strip that from the messages we receive to restore previous behaviour.

Lightbox Viewer URP for the Basis Framework has been added as a new package.

This package is meant to be used on URP

This early version does not support post-processing, and it does not support traditional Light Probes.

🗒️ Open documentation.

As I am no longer focusing on VRChat content creation, the following packages will now install in ALCOM without warnings, even if VRChat introduces breaking changes:

• Animator As Code - VRChat V1.1.2
• Animator As Code - VRChat Destructive Workflow V1.1.2
• Animator As Code - Modular Avatar V1.1.2
• Prefabulous for VRChat V2.2.0
• Auto-reset OSC config V1.1.6
• ComboGestureExpressions V3.3.1

VRChat Avatars package upper bound dependency raised to VRChat SDK999.

Prefabulous for VRChat V2.2.0​

• Now requires Animator As Code 1.2.0 or above, in order to use the asset container provider API.
• Add support for cross-application build compatibility being introduced in NDMF 1.8.
  • This explicitly prevents the VRC-specific plugins from being executed in Resonite builds.

Animator As Code V1.2.0​

• Add support for third-party asset container management.
  • In preparation for the introduction of IAssetSaver in NDMF 1.6.0, add the ability to delegate the management of the asset container to a third party.
    • No new dependencies are added.
    • By default, the behaviour of Animator As Code is the same as V1.1.0.
  • Add new optional field AacConfiguration.AssetContainerProvider to specify an asset container provider.
  • Add new interface IAacAssetContainerProvider to abstract asset container management.

The above changes have been contributed by kb10uy (KOBAYASHI Yū) (first contribution).

The NDMF example in the Getting started page has been updated to demonstrate integration with this new API.

As specified in the changelog for the official release of Animator As Code V1, breaking changes had been planned, and will be applied starting this version:

• AacFlSettingKeyframes constructor is now private.
  • For compatibility reasons, it was public for the duration of V1.1.x, and was already marked as obsolete in V1.1.x.
• The methods AacFlBase.InternalConfiguration and AacFlBase.InternalDoCreateLayer are now private.
  • For compatibility reasons, it was public for the duration of V1.1.x, and was already marked as obsolete in V1.1.x.
  • The class AacAccessorForExtensions replaced them.

These breaking changes are meant to be the last breaking changes for the lifetime of Animator As Code V1.

• Make AAC 1.2.0 a requirement, as AAC 1.2.0 adds additional argument checks for compatibility with Vixen.
• Include contributions from @TayouVR and @yewnyx that make this package better installable via git url.

• Add Collections of lightboxes. Users may now switch from the default six lightboxes to other more specialized ones.
  • Add special lightboxes specifically for Light Volumes. This requires the Light Volumes package to be installed.
  • Expose the Spotlight Cookie lightbox that was previously hidden.
• Previously, lights inside the object being viewed were disabled. This is no longer the case by default.
• Add option to disable lights inside the object being viewed.
• Add option to support shaders that require a Depth Texture.
  • This uses Poiyomi's DepthGet light settings, but repackaged with a different GUID to avoid installation conflicts.
• The Advanced menu is now a sidebar.
• Some settings are now saved editor-wide, instead of being reset when the Lightbox Viewer window is closed.
  • This includes Counter Rotate, Post Processing, Vertical Displacement, Mute Lights Inside Object, Support Depth Texture.

Add support for Light Volumes if it is installed in the project.

The lightboxes themselves do not change, so the differences are subtle. The Pink scene is the most notable because the left hand will be lit pink and the right hand will be lit purple.

This update is targeted specifically at Modular Avatar for Resonite users.

This update enables all Prefabulous Universal components to execute during builds targeting the Resonite app.

If you use Modular Avatar for Resonite, it is very likely you already have prerelease packages enabled in ALCOM, meaning you may update Prefabulous Universal to V2.2.0-alpha.0 using ALCOM.

If you use FaceTra Shape Creator, you need to download a patch linked here, no log-in required.

Prefabulous Universal 2.2.0-alpha.0​

Support Modular Avatar for Resonite:

• Add support for cross-application build compatibility being introduced in NDMF 1.8.
• Conditionally compiled when NDMF 1.8.0-alpha.0 is installed:
  • Prefabulous Universal still needs to be compatible with VNyan (Unity 2020) and Warudo (Unity 2021), meaning we still need to support NDMF 1.4 (last known working version in Unity 2020).

Prefabulous for Platform Conversions 2.1.0-alpha.0​

• Fix ConvertVRCConstraintsToUnityConstraints should run after Modular Avatar creates constraints:
  • Run after Modular Avatar, because MA Convert Constraints and MA World Fixed Object create VRCConstraint.
  • Also, remove this component during the build to help missing script issues (e.g. better handles CVR).
  • The above changes have been contributed by Narazaka (first contribution).
• Integrate with NDMF 1.8 cross-application builds:
  • Add support for cross-application build compatibility being introduced in NDMF 1.8.
  • MA/NDMF for Resonite does not support Unity constraints at this time of writing, but as far as I am aware there is no harm done enabling this conversion plugin pass for all platforms.
  • Conditionally compiled when NDMF 1.8.0-alpha.0 is installed:
    • Prefabulous for Platform Conversions still needs to be compatible with VNyan (Unity 2020) and Warudo (Unity 2021), meaning we still need to support NDMF 1.4 (last known working version in Unity 2020).

A new menu option named Activate with Skinned Offsets is added in the inspector of the Parent Constraint and VRC Parent Constraint components.

Pressing this menu option will behave similarly to the Activate button on the Parent constraint, but calculates different offsets: These offsets will make the Parent constraint behave more like weight painting/mesh skinning.

This is the same algorithm that is used by the Skinned Mesh Constraint Builder component. If you are already using this component, you do not need to use this.

🗒️ Open documentation

A new component, Skinned Mesh Constraint Builder, has been introduced to a new package.

This component creates a parent constraint that moves with the closest polygon of a Skinned Mesh Renderer.

Use this component when you notice that attaching an object to your body is not as straightforward as parenting to a bone.

You may install the new package Haï ~ Skinned Mesh Constraint using ALCOM.
