Added Magica Cloth AreaWind to the VSeeFace SDK whitelist.
Added Spout.InvertCamera to the VSeeFace SDK whitelist.

Version 1.13.38b3:

Fixed an issue where props could disappear when being attached.
Updated the Leap Motion LeapC.dll for better compatibility with the V5.7.2 Ultraleap software.
Added a VSF_SpoutReceiverSettings component to the VSeeFace SDK, which allows converting from sRGB to Linear colorspace correctly.

Improved the error message that appears when the tracker process disappears

Version 1.13.32b:

The version number was actually not changed. This fixes some issues where the tracker wouldn't start due to an incompatible version of DLLs being included. The issue only appears on systems without VC++ runtime files installed, so if 1.13.32 is working fine for you, there is no need to download again.

Version 1.13.32:

Added a rough and basic tutorial that is displayed at first start or accessed from the help screen (I'll try to make it look nicer in the future)
Added a new very fast toaster grade tracking quality mode (around four times faster) without blink, gaze and expression tracking for low spec PCs
Added a language choosing dropdown menu on the starting screen
Tried adding Japanese translations for parts of the UI

Fixed an issue where a set resolution would temporarily be reset when closing the program when the window is allowed to be resized
Fixed some text input boxes looking empty at certain window sizes
Added a slider to adjust eye blink smoothing
Added a slider to adjust neck stiffness, making head tilts without moving the whole body easier when set to a lower value
Made it so audio input is automatically reinitialized if no more audio data is received for three seconds after originally receiving audio input
Fixed gaze tracking issues introduced recently
Made further fixes the camera based part of hybrid lip sync, hopefully stopping it from randomly not working
Removed enable effects checkbox (handled automatically)

Version 1.13.31c:

Fixed a bug where calibrating the experimental expression detection would be impossible with certain models

Version 1.13.31b:

Fixed a bug with the smoothing and sensitivity default value for the new simple expression detection being incorrect

Version 1.13.31:

Added a frame rate and tracking rate display in the lower right corner
Added an option to the effect settings to enable post processing based smoother anti-aliasing (slightly increases GPU usage)

Added new simplified expression detection mode that doesn't require calibration (fun, angry, surprised only)
Added an option to make eye blink detection less sensitive when looking down
Added a surprised expression to the default avatar
Fixed an issue where the mouth wouldn't open through camera tracking with hybrid lipsync

Version 1.13.30:

Fixed bloom effect, allowing it to bleed outside the area covered by the avatar
Added an option to limit the bloom effect to the area covered by the avatar
Added an option to let the grain effect affect the whole image
Added a slider to influence how strongly the grain will affect transparent areas
Added a slider to influence the alpha values of bloom on transparent areas
Prevented effects from running during the starting UI
Fixed the ambient occlusion effect
Added tutorial link right next to the expression detection option
Prevented expressions getting stuck when expression detection is disabled or tracking is lost
Fixed disappearing text in dropdown menus at some window sizes
Allowed settings windows to move in front of UI buttons

Version 1.13.27:

Fixed screenshot hotkeys being active on the start screen
Fixed an issue where broken avatars could not be removed from the avatar selection UI
Fixed further bugs that occurred when using the screenshot function, which could lead to the screen being flipped
Fixed screenshots with "Really nice" anti-aliasing
Changed the background to be transparent even with the UI showing
Added post processing image effects (Bloom, ambient occlusion, lens distortion, chromatic aberration, color adjustment, grain). Only the image area covered by the avatar itself will show up as affected in OBS.

Version 1.13.25b:

Fixed avatar height based scaling of tracking space for Leap Motion tracking with chest and head positions

Version 1.13.25:

Added a new avatar selection UI made by Deat
Loading avatars no longer freezes the program, so the "L" hotkey might actually be useful now, but it might still lag a bit

Added a transparent background image for use with the virtual camera's ARGB mode in VSeeFace_Data\StreamingAssets\
Made the Leap Motion model visible while inside the avatar mesh
Changed the UI hiding button to also hide the Leap Motion model
Fixed a bug where the IK target's position could be off when reverting to the default model
Made it so that the tracking space scales with avatar height as determined by vertical position of the head bone to properly support very small and very big avatars
This means that the motion range and leap motion scale values need to be adjusted a bit
Added an option to make the synthetic gaze look at the camera
Added an option to set a custom default camera
Disabled automatic recalibration when the face seems to teleport and after 0.4 seconds, the new position is simply accepted

Enabled no-3d-adapt tracker option to stabilize expression detection and prevent people from randomly flying off after a while
Fixed a bug where the face tracking background process could be started by other options, even though it was stopped by the main option in the general settings
