Hello everyone,

Populating your world with multiple AI characters brings 3D environments to life, but driving seamless, intent-aware voice interaction across a shared scene requires precise targeting.

In **Part 1 of our Multi-Character Sessions tutorial series** for Unity, we bring three distinct Convai AI avatars (Sophia, Ethan, and Marcus) into a single scene and demonstrate how to route player dialogue dynamically based on gaze, proximity, and direct targeting.

### ✨ What We Cover in Part 1

We walk through setting up your scene and configuring character targeting using the Convai Manager:

- 👥 **Multi-Character Setup:** Assign unique Character IDs to multiple AI avatars within a shared Unity scene.

- 👁 **Look At Selection:** Automatically route voice input based on where the player is looking in the 3D space.

- 📍 **Proximity Selection:** Dynamically target characters based on their physical distance from the player.

- 🗣 **Fluid Conversation Switching:** Transition between individual AI characters in real time without dropping conversation state.

_(Note: In Part 2, we will expand this workflow to include all-to-all multi-character awareness, allowing AI characters to perceive and react to ambient conversations happening around them!)_
