Spout

Spout is a new way of screen capturing using only GPU power and can replace the default game / window capture of OBS.

• Install the Spout2 OBS Plugin.
• Add a Spout2 capture source to your scene.
• Select Premultiplied Alpha as composite mode for transparent background.

Please note that this system might not work on certain GPUs.

Webcam Tracking

• Use a bright front-facing light. Tracking quality drops hard in dim rooms, and many webcams silently lower their real frame rate in low light.
• Avoid strong backlighting. If the background is much brighter than the face, tracking becomes less stable.
• If you wears glasse, place lights to avoid reflections. Ring lights can help with brightness but can also create glare that hurts eye tracking.
• 720p to 1080p is the practical sweet spot. Higher resolutions usually do not help much; 640x480 can work but tends to be more jittery, especially for eyes.
• A wide-angle webcam gives more room to move before tracking is lost at the edge of frame.
• For 720p/1080p, USB3 cameras are preferable to USB2 because USB2 often relies on compressed formats like MJPEG, which can reduce tracking quality.
• More than 30 FPS is usually not necessary for face tracking. It increases CPU cost more than it improves visible smoothness.
• Eye tracking is generally the least reliable part of webcam tracking. Mouth and head motion are usually more robust than fine eye detail.

FAQ

The Login is broken

• Please download the latest version of VTuber Plus from itch.io

I've purchased VTuber Plus before. Do I need to purchase it again to receive the update?

Do I need to keep VSeeFace running in the background?

No. VTuber Plus has it's own face tracking. You can also use other tracking software with VMC protocol such as VSeeFace if you wish to do so.

Can I use Live2D avatars?

VTuber Plus only supports VRM and VSF avatars at the moment. Live2D support is planned for the future.

Items are being thrown at my feet.

Try increasing the Physics quality in Physics Settings.

VTuber Plus is being laggy while running along side my game.

• Make sure to cap the fps in your game.
• Hide your avatar in VSeeFace.

My avatar's facial expressions are partially missing in VTuber Plus. I'm using ARKit.

Make sure you have all 52 required blendshapes setup on your avatar. Even if your expressions look normal in VSeeFace, only the blendshapes can be sent over VMC.

My eyebrows are not working outside of VSeeFace.

For any animation or tracking to work outside of VSeeFace you must make sure that the blendshapes are available on the avatar. Eyebrows are "Brows up" and "Brows down". If they are missing, they can not be transferred using the VMC protocol. More info on the special blendshapes can be found here.

My shirt / skin around the armpit area is pointing outwards.

Change your render quality to High or Ultra.

I'm experiencing low performance / fps.

Use Spout renderer and turn on No visuals.

How do I make groups of custom items?

Simply put your items in a subfolder.

How do I set up my OBS for Spout2?

How do I set up my OBS for Game Capture?

My webcam works in other apps, but not in VTuber Plus

VTuber Plus uses OpenSeeFace for webcam tracking. Some webcams can appear normally in Windows, OBS, Discord, or other apps but still fail when OpenSeeFace tries to read their supported camera modes. If this happens, try Camera Defaults first instead of picking a specific resolution. If that still fails, test the same webcam in OBS and note which resolution and frame rate actually work, then use those settings in VTuber Plus.

The camera is detected, but tracking does not start

Make sure no other application is currently using the webcam. Close OBS, Discord, browser tabs, camera apps, and any virtual camera software before starting tracking. If another program has locked the camera, VTuber Plus may see the device name but fail to start the tracker.

Tracking is very shaky or keeps getting lost

Webcam face tracking needs a clear, well-lit view of your face. Use bright front lighting and avoid strong backlighting from windows, LED panels behind you, or bright monitors in the background. If the camera image looks dark, grainy, or noisy, tracking quality will drop sharply.

Eye tracking is unstable

Eye tracking is usually the least reliable part of webcam tracking. Glasses reflections, dim rooms, low camera quality, and strong shadows around the eyes can all reduce stability. Try improving front lighting, reducing glare on glasses, and positioning the webcam closer to eye level.

Tracking works for a while, then randomly stops

Windows may be putting the webcam's USB port to sleep. Disable USB power saving for the webcam's hub or root hub in Device Manager, and consider disabling USB selective suspend in Windows power settings. This is a common cause of webcams disconnecting or freezing during tracking.

Blinking, mouth movement, or expressions look wrong

For VRM avatars, the required blendshapes must be registered as VRM blendshape clips. Having raw mesh blendshapes on the model is not enough. If blinking triggers strange mouth movement, shadows shift during expressions, or custom clips do not appear, the avatar likely needs to be corrected and re-exported.

My mouth tracking looks bad

For standard webcam lipsync, make sure your avatar has A, I, U, E, and O blendshape clips. If the model uses texture-based mouth shapes or material offsets, mixed visemes may look broken. In those cases, the avatar setup may need to be adjusted to support webcam lipsync correctly.

Eyebrows are not moving

Eyebrow tracking requires custom blendshape clips named Brows up and Brows down. If those clips are missing, eyebrow tracking will be limited or unavailable.

The tracker loses my face when I move

Keep your face clearly visible and avoid turning too far away from the camera. Large head turns, leaving the frame, or heavy occlusion from hands, microphones, hair, or props can interrupt tracking. A wider-angle webcam can help if you tend to move around a lot.

My question isn't listed here. Where can I get support?

There is a Discord server provided in the program.
