Blinking eyes

Eye L Open and Eye R Open run from 0 (closed) to 1 (open), with 1 as the default.

1. Mesh the eye

Give the eyelid, upper lash line and the eye white real meshes (Mesh editing): the lid and lashes need points along their length to bend.

2. Two keys

On Eye L Open, add keys at 0 and 1. Key 1 is the open eye you drew, so leave it.

3. Close it

1. Move the slider to 0.
2. Select the upper lash line and lid, and drag their points down onto the lower lash line. The Deform Brush is quick for this: push the lid down along its length.
3. The eye white and iris should vanish as the lid closes: clip them by the eye white (Clipping masks), then squash the eye white's points to the closed lid line at key 0 so the iris goes with it.

Drag the slider back and forth: the eye blinks.

4. The other eye

Repeat on Eye R Open. Keep the IDs ParamEyeLOpen and ParamEyeROpen: export fills the EyeBlink group from them, so VTube Studio blinks the model by itself.
