Light face tracking
Widgets that
find your face.
Widgets can follow you instead of sitting in a corner: your conditions ride above your head, your nameplate sits under your chin. Lean out of frame and they slide back to their fixed spots.
Light, on purpose
It finds where your face is. That's all.
Vellum uses a small face detector: a box around your face and six points. It doesn't read expressions, it doesn't recognise who you are, and it never changes your stats.
Small
The model is about 230 KB and runs a few milliseconds per frame on a normal CPU.
Smooth
It checks your position about 15 times a second, and widgets glide between checks so they don't jitter.
Idle when unused
If no widget in your frame is anchored to your face, the detector doesn't run at all.
Strictly local
Camera frames never leave your machine.
With tracking on, the Vellum page inside OBS opens your webcam itself, draws it, finds your face and lays the HUD on top, all in one place. The model is served from vellumhud.com with the app, never from a third party, and nothing is sent back.

Setup
One extra step.
OBS has to be started with camera access for browser sources turned on. The app's setup panel spots when it's missing and shows the exact fix for your system.
Start OBS with the camera flag
Launch OBS with
--enable-media-stream. The guide has a shortcut per OS.Use the camera scene
Pick the "Vellum camera" scene, which lets Vellum draw your webcam itself.
Choose a frame with anchors
Frames that use face anchors say so in the picker.
