2. Export as FBX: Navigate to `Edit > Export FBX` and choose the `Blender` preset. Ensure that you deselect `Embed Textures` under FBX options.

3. Save Your File: Choose your project folder and save your character model.

Step 2: Adding Animations

1. Select Animations: Use the search bar to find `idle` and `talk` animations.

2. Export Animations: Export each animation as an FBX file, following the same steps as above.

Preparing Blender

Step 1: Installing Add-Ons

1. Download Blender Add-Ons: Get the `CC Blender Tool` and `Baking Add-On` from GitHub.

2. Install Add-Ons: Install these add-ons through the Blender preferences and enable them.

Step 2: Importing and Preparing Character

1. Import Character: Use the pipeline tab in Blender to import your character.

2. Rebuild Materials: Convert materials for web compatibility by selecting `Basic` and then `Rebuild Basic Materials`.

3. Bake Textures: Use the baking tab to bake textures into a designated bake folder.

Step 3: Exporting for Web

1. Export as GLTF: Ensure that you deselect `Animation` in the export options and save your file as a GLB.

2. Validate: Check your file in a GLTF viewer to ensure everything is correct.

Creating AI Minds with Convai

1. Create a New Character: Sign in to Convai and create a new character. Choose a voice and backstory.

2. Set Up Personality: Adjust personality traits to suit your character’s role. Learn more here.

3. Copy Character ID and API Key: You will need these for integrating Convai with your web setup.

Setting Up the React Environment

Step 1: Setting Up the Project

1. Create a React App: Use `npm create vite@latest .` to set up your React environment.

2. Install Dependencies: Install required packages like `react-three-fiber`, `drei`, `three.js`, and `lodash`. Read React Documentation here.

Step 2: Configuring the Environment

1. Setup 3D Space: Use `react-three-fiber` to create a 3D space. Configure lighting, sky, and grid components.

2. Implement Controls: Use `Convai FPS control` for first-person shooter-style movement.

Bringing it All Together

Step 1: Importing and Mapping Characters

1. Convert GLB Files: Use GLTF React Three Fiber tools to map nodes and materials.

2. Setup Animations: Extract and set up animations using `useAnimations` and `useConvaiClient` hooks. Additional information here.

Step 2: Implementing AI and Interactions

1. Lip Sync and Head Tracking: Use `useLipSync` and `useHeadTracking` hooks to enhance interactivity. Learn more here.

2. Crowd Characters: Import additional characters from Reallusion and set up animations similarly.
