Expressive Ears

The Expressive Ears template provides you with three different sets of 3D animal ears that respond to different facial expressions: happy (smile), sad (frown), and angry (grimace). The visual scripting combines Face Avatar Result nodes with blendshapes to achieve this effect.

Blendshapes

Let's take a look at the blendshapes of an ear's mesh. Select a mesh, like RabbitEarR_Mesh, in the Hierarchy panel. Go to the Inspector panel and locate the Deformation component.

blendshapes

There are three blendshapes for happy, sad, and angry. These blendshapes are used to drive visual scripting based on the user's expression.

Assets

The Assets panel houses the materials, models, and textures that make up the expressive ears.

Visual Scripting

Try smiling, grimacing, and then frowning! The ears move depending on the facial expression that is detected. Each expression has Face Avatar Drive nodes to track the position and movements of the facial features.

The detected facial expressions are then calculated as values and applied to the ears.

The calculated values also act as outputs and can be attached to other values.
