[Unity Tool - VRChat] Facial Expression Creator – Create & Edit Facial Animations | BlendShape Browser [PC - Quest - iOS] | English, Español, 日本語, Deutsch, 한국어, 简体中文

Facial Expression Creator

Facial Expression Creator is a Unity tool made to simplify the creation and setup of facial expressions for VRChat avatars.

It lets you create Animation Clips from your avatar's BlendShapes, edit existing clips, configure expressions for both hand gestures, and add expressions controlled through the Expressions Menu.

The tool can automatically detect the face from the Face Mesh configured in the VRC Avatar Descriptor. You can also manually select a GameObject or Skinned Mesh Renderer if you want to work with a specific mesh.

Work modes:

New Animation Clip

Edit Clips

Gesture Matrix

Menu Gestures

Creating and Editing Animation Clips

Select the BlendShapes you want to modify, adjust their values, and check the result

directly on the avatar using Preview

Only the BlendShapes you mark for modification Will be saved to the new

Animation Clip, so you can test values without having to include them in the final

result

You can also load existing Animation Clips and edit them

Clips can be selected manually or detected from the avatar's FX Controller. The tool

can find the standard VRChat gestures as well as expressions used inside an existing

Gesture Matrix

When editing a clip, you can add or update BlendShapes without removing the rest

of the animation, or replace its contents depending on what you need

Visual BlendShape Browser

When an avatar has hundreds of BlendShapes, finding the one you need by name

alone can be inconvenient

Facial Expression Creator can generate a thumbnail for each BlendShape using the

Scene View, so you can quickly see which part of the face it affects

You can search by name, apply filters, and sort the results

Thumbnails can also show only the affected area or highlight the vertices modified

by each BlendShape

You can adjust their resolution and size, and generated thumbnails are cached so

they can be reused whenever possible

Gesture Matrix

The Gesture Matrix lets you configure all 64 possible combinations between

GestureLeft and GestureRight

Each hand uses the eight standard VRChat gesture values:

Default, Fist, Open Hand, Point, Victory, Rock 'n Roll, Gun, and Thumbs Up

You can assign a different Animation Clip to each combination or reuse the same

clip in multiple positions

If the avatar already has facial expressions configured, the tool can read its FX

Controller and try to automatically import the existing matrix

You can also adjust the transition time between expressions

Animation Clip Checks

A facial expression can remain partially active when two Animation Clips do not

control the same BlendShapes

The Gesture Matrix checks for this type of difference between the Default clip and

the other expressions

When it finds a problem, it shows a warning and provides an Auto Fix option that

adds the missing BlendShapes with a value of O

This helps prevent parts of a previous expression from staying active when

switching gestures

FX Controller Generation

Once the Gesture Matrix is ready, you can generate the system directly from the

tool

Facial Expression Creator creates a new FX Controller instead of modifying the

original

You can keep the avatar's existing facial layer and add the new Gesture Matrix, or

replace that layer inside the generated copy

The rest of the controller layers are preserved

Once generated, you can assign the new FX Controller to the avatar from the same

window

Expressions from the Expressions Menu

Not every expression has to depend on hand gestures

Menu Gestures lets you create facial expressions that are activated directly from the

VRChat Expressions Menu

For each expression, you can configure:

Animation Clip

Name

Icon

Save State

Thumbnail

Destination inside the Expressions Menu

The expressions use one shared Int parameter

When a menu expression is active, it takes control of the face. When disabled, the

avatar automatically returns to the expression that matches the current Gesture

Matrix combination

Expressions Menu Organization

You can choose an existing menu or prepare new submenus before generating the

system

The tool shows the controls that already exist, the ones you are preparing, and the

available space in each menu.

If a menu runs out of space, you can configure additional submenus without having

to create them manually first.

The new menus and controls are created when you generate the system
