Release Notes

V4.0.4

Improvements / New Features

- Added new hand collider generator tool window in Window/Autohand/HandColliderEditor (Contribution from "Silk" in the discord)

- Added new advanced settings to hand follow component for "maxDistanceNoParentReleaseFrames" and "maxDistanceParentReleaseFrames" which will allow customization on how long it takes for the hand to release an object if it's stuck or not teleportable

Bug Fixes

- Fixed bug with hand tracking and controller swapping on MetaXR causing the hand posing to freeze

- Fixed bug causing controller pose areas not to work when hand tracking swapping enabled

- Fixed bug with teleport point spamming start and stop events

- Fixed bug with objects dropping out of hand while using virtual desktop or moving hands extremely quickly

- Fixed warning "Setting linear velocity of a kinematic body is not supported" when grabbing kinematic objects from place points

- Fixed incorrect setting on the Teleporting prefab allowing default settings to teleport on the player

- Fixed missing reference is MetaXR sub-package

V4.0.3

Bug Fixes

- Fixed bug with the hand tracking that causes them to jump to the floor when hand tracking is lost. Hand tracking should now freeze until tracking is regained or controllers are grabbed

- Fixed missing reference in Meta XR package

- Removed XRHands reference from MetaXR package that causes an error if the unrequired xr hands package is not installed

- Adjusted some highlight materials for the Meta XR demos so they dont appear overly inflated in the android build

V4.0.2

Improvements / New Features

- Added support for latest Meta SDK package

- Added handtracking demo for Meta SDK package

- Added passthrough demo for Meta SDK package

- Added Teleport Points

- Added Teleport Point Animtion Component

- Added Teleport Point only toggle to Teleporter

- Added Smooth Stepping settings to Auto Hand Player

- Added Trigger Query Setting to Hand Highlighter to allow togging for grabbing grabbable using trigger colliders

Bug Fixes

- Fixed issue with hand tracking not working properly through steamlink

- FIxed issue where hand tracking stops working when taking the headset off and putting it back on

- Fixed bug with Auto Hand Player SetPosition function not working properly when using a custom rotation input

- Improved sweep test logic with Player SetPosition function to prevent hands from clipping into static colliders

- Improved sweep test logic to teleporter to prevent hand clipping when teleporting into static colliders objects with hands

- Teleporter now checks for the player capsule to prevent player from teleporting under objects it cannot fit

- Adjusted some smooth movement settings for UI pointer and Distance Grabber. Also added a toggle to remove smooth movement completely from UI pointer and Distance Grabber

V4.0.0

Changes to Hand Component

- Hand logic is now split into additional scripts. None of these scripts need to be manually added. All these scripts and their recommended values will be automatically applied to each hand component.

- Hand Follow now manages the hand movement instead of Hand.cs. Includes public values and functions for previous movement settings, including exposing additional movement settings that were previously internal

- Hand Follow now includes options for dynamic hand mass. This will increase the hand mass based on its distance from the target position/rotation. This allows the hands to more realistically touch things without knocking them around.

- Hand Follow: some of the default settings have been changed for hand-hand movement. Hands should now feel more “snappy” and less “wobbly” when dealing with rotation/weight.

- Hands should feel less “caveman-like” when touching dynamic objects, no longer as forceful until you push against the objects. Important for good feeling hand tracking.

- Hand Follow now manages two-handed grabbing forces better by limiting the range of the move target to be based on each other hands target positions. Things like a steering wheel and pulling objects apart in opposite directions should feel more realistic

- Hand Grabbable Highlighter now manages the internal highlight functions. Hand.cs still manages the highlight settings except internal OnHighlight and OnStopHighlight event delegates will need to be changed to hand.highlighter.OnHighlight += MyEventFunc

- Hand Grabbable Highlighter will now by default favor highlighting objects near the fingers/fingertips instead of the palm face. Use the highlighter palmForwardRightDirection value to choose which angle will have more priority when grabbing

- Hand Animator now manages the hand posing instead of Hand.cs. Includes the public values and settings for hand-posing and hand sway. Hand.cs still includes auto posting function

- Additional setting requirements for the Finger component. Each finger now requires a setting for which finger type it is (index, middle, ring, pinky, or thumb), and manually connected references for each finger joint transforms. This allows for more dynamic control over the finger data/posing and helps prevent data corruption when changing the hand’s hierarchy

- Changes to the way HandPoseData is managed internally.

Existing poses will need to be updated through the update window.

When entering a new scene, if any deprecated pose data is detected, a window will open and prompt you for the left/right copies of all the hands used for poses in this scene. Include your hands, press “Find Prefab Poses” if you’re using these included hands in your prefabs. Finally press “Update Poses”

New Auto Pinch Settings

- The hand will now take two new poses for Pinch Open, Pinch Closed. The hand will also take a new value called “Pinch Point” value. The “Pinch point” is similar to the “Palm” value in that it represents the center point of the pinch grab. It should be centered between the index/middle/thumb when the hand is in a closed pinch pose state.

Grabbables set to grab type pinch will be pinch grabbed from any angle if the hands are setup for pinching

- Improved Hand Tracking. The previous hand-tracking solution took the data from the hand-tracking pose and used it to interpolate each finger from open to closed. This solution worked to support hand tracking (in a minimalistic sense) without compromising other features, but it was a stiff and limited solution. The new solution allows for complete freedom of movement for each finger, it allows for multiple options for grab/release triggering: including finger-tip touch grabbing and making a grasping motion while targeting a grabbable, this combination makes for a much more natural feeling hand tracking experience.

- Simple Desktop Player. Added a simple demo for desktop users at [Auto Hand/Examples/Scenes/Desktop], which controls the left/right hand by holding the left/right mouse. Pressing space will toggle grab/release for hand when holding left/right mouse button. WASD to move and the mouse will turn head when not controlling hands. Not meant to be a game-ready solution just useful for testing simple features without going in and out of VR
