VTube Studio Actions
Published 11 Sept 2026
Nine actions that drive your Live2D model from anything TipLink can see: a tip, a sub, a chat command, a channel point redemption.
What You Need
- VTube Studio connected in TipLink. See VTube Studio for setup.
- A model loaded in VTube Studio. Most of the dropdowns below are filled in from the model you currently have open.
Sizes, positions, values and durations all take placeholders, so you can drive them from the event. {{ value }} in a parameter's Value field makes a bigger tip push your model further.
The Actions
| Action | What it does |
|---|---|
| Trigger Hotkey | Fire one of your model's hotkeys |
| Set Expression | Turn an expression on or off |
| Drop Item | Put a prop, sticker or animated item on screen |
| Move Item | Slide, resize or spin an item already on screen |
| Control Animated Item | Play, stop or restyle an animated item |
| Remove Item | Clear an item off the screen |
| Set Parameter | Drive a tracking or custom parameter |
| Switch Model | Load a different model |
| Physics Burst | Briefly change how much hair and clothing move |
Trigger Hotkey
Fires one of your model's hotkeys, exactly as if you had pressed it.
| Option | What it does |
|---|---|
| VTube Studio Account | Which connected account to use. |
| Hotkey | The hotkey to fire. The list comes from the model you currently have loaded. |
If you also have an alert triggering on Hotkey Triggered, leave that trigger's Ignore Hotkeys TipLink Fired switched on, or the two will set each other off. It is on by default.
Set Expression
Turns one of your model's expressions on or off.
| Option | What it does | Default |
|---|---|---|
| Expression | The expression to change, from your loaded model. | - |
| Turn It | On or Off. | On |
| Fade Time (Seconds) | How long the expression takes to blend in or out. | 0.5 |
Drop Item
Drops a prop, sticker or animated item onto the screen.
| Option | What it does | Default |
|---|---|---|
| Item | The item to drop, from your VTube Studio items folder. | - |
| Horizontal Position | -1 is the left edge, 0 the middle, 1 the right edge. | 0 |
| Vertical Position | -1 is the bottom, 0 the middle, 1 the top. | 0 |
| Size | Between 0 and 1. Around 0.32 matches VTube Studio's own default. | 0.32 |
| Rotation (Degrees) | How far to rotate the item. | 0 |
| Fade In Time (Seconds) | How long it takes to fade in. 0 appears instantly. | 0 |
Put a Random Number action before this one and use its placeholder in Horizontal Position, so the prop lands somewhere different every time.
Move Item
Slides, resizes or spins an item that is already on screen.
| Option | What it does | Default |
|---|---|---|
| Item | Every copy of this item currently on screen will move. Drop it first. | - |
| Horizontal Position | -1 left, 0 middle, 1 right. | 0 |
| Vertical Position | -1 bottom, 0 middle, 1 top. | 0 |
| Size | Between 0 and 1. | 0.32 |
| Rotation (Degrees) | How far to rotate. | 0 |
| Over (Seconds) | How long the movement takes. 0 snaps instantly. | 0.5 |
| Movement Style | Smooth, Steady, Slow start, Slow finish, Overshoot or Zip. | Smooth |
Control Animated Item
Plays, stops or restyles an animated item already on screen.
| Option | What it does | Default |
|---|---|---|
| Item | Every copy on screen is controlled. Drop it first with Drop Item. | - |
| Playback | Play or Stop. | Play |
| Frame Rate | Animation speed in frames per second. | 30 |
| Opacity | Between 0 (invisible) and 1 (fully visible). | 1 |
| Brightness | Between 0 (black) and 1 (normal). | 1 |
Remove Item
Clears an item off the screen. Every copy of that item currently on screen is removed.
| Option | What it does |
|---|---|
| Item | The item to remove. |
If the item has not been dropped, the action is skipped rather than reported as an error.
Set Parameter
Drives a tracking parameter, a Live2D parameter, or a custom one of your own.
| Option | What it does | Default |
|---|---|---|
| Parameter | One that already exists, or Create a custom one. | Existing |
| Which Parameter | The parameter to drive, from your loaded model. (existing only) | - |
| New Parameter Name | 4 to 32 letters and numbers, no spaces. You must rig this into your model to use it. (custom only) | - |
| Minimum Value / Maximum Value | The range the custom parameter can take. (custom only) | 0 / 1 |
| How To Apply It | Replace the value, Add on top of tracking, or Stop controlling it. | Replace |
| Value | The value to apply. Placeholders work, so a tip amount can drive it. | 1 |
| Hold For (Seconds) | How long to hold it before your tracking takes over again. 0 holds until something changes it. | 3 |
| Strength | Between 0 and 1. Below 1 blends with your live tracking instead of replacing it. | 1 |
Replace or Add?
Add on top of tracking is usually the one you want for alert effects. It layers on top of your face tracking and coexists with other plugins.
Replace the value takes the parameter over completely, and only one plugin can hold a parameter that way at a time.
VTube Studio hands a parameter back to face tracking unless something keeps restating it. TipLink does that for you while the hold lasts. When the hold expires, or the account disconnects, the value simply reverts, so there is no undo to run.
Switch Model
Loads a different model.
| Option | What it does |
|---|---|
| Model | The model to load. |
VTube Studio enforces a two-second cooldown on model loads. Alerts that could fire in quick succession should not both swap the model.
Physics Burst
Briefly exaggerates or kills the movement of hair, clothing and accessories, then puts it back on its own.
| Option | What it does | Default |
|---|---|---|
| Physics Group | The part of your model to affect, from its physics settings. | - |
| Affect | Movement makes things swing more. Wind pushes them sideways. | Movement |
| Amount | Between 0 and 2. 1 is normal, 2 double, 0 stops it completely. | 2 |
| For (Seconds) | Between 0.5 and 5 seconds, then it returns to normal by itself. | 2 |
Values outside those ranges are clamped rather than rejected, so a placeholder that produces something wild still runs.
Common Uses
| Idea | How |
|---|---|
| Blush on every tip | Set Expression, on, with a short fade |
| Bigger tip, bigger reaction | Set Parameter with {{ value }} in Value, set to Add |
| Confetti on a raid | Drop Item, then Remove Item on a Delay |
| Hair goes wild on a gifted sub | Physics Burst, Movement, Amount 2 |
| Costume change at a goal | Switch Model |
