Adding NPC/Avatar Agents

Overview

E-Learning Lab lets you add non-player character (NPC) agents into scenes, starting with version 1.4.2. This lets educators populate virtual environments with interactive avatar characters.

Adding Avatars to Your Scene

Basic Method

Drag and drop avatars from the Avatars tab in the assets browser directly into the preview window, scene editor, or Inspector tool.

Avatar Sources

• Built-in avatars provided within E-Learning Lab
• Custom avatars from any library in .fbx, .glb, or .glTF formats

AI-Generated Avatars

As of version 1.4.11, you can generate fully rigged avatars using:

• Photo-based generation
• Text prompt-based generation

This requires an API key for either Meshy or Tripo.

Customization Options

Animation States

Select specific animation states for your avatars. Available animation options can be reviewed in the Inspector panel under the Animations tab.

Facial Expressions

Right-click on an avatar to access facial morph controls, letting you customize expressions and facial features for more realistic and expressive educational scenarios.
