Reallusion Avatars

Upload custom Reallusion characters from Unreal Engine to Avatar Studio using the Convai Asset Uploader.

Introduction

This guide explains how to prepare and upload Reallusion-based avatars using the Convai Asset Uploader. You’ll import your Reallusion character and animations, apply Convai’s animation and lipsync systems, and then upload your avatar to Avatar Studio using the built-in AssetUploader tool.

Prerequisites

Make sure you have the following ready:

• A project created with the Convai Asset Uploader, where you answered N to “Are you using a Metahuman?”

• A custom Reallusion character exported and ready for import

---

Step-by-Step Guide

1. Open the Project

Navigate to your project directory and open the .uproject file to launch it in Unreal Engine.

---

2. Import Reallusion Character & Animations

Follow this video tutorial to import your Reallusion assets:

• [00:00 – 07:25]: Import your character and animations

• [07:50 – 08:20]: Create a new Blueprint Class for your character

---

3. Connect Convai Animations

Now we’ll bind the correct animation logic to your character.

We’ve already added the necessary Animation Blueprint for you:

• Go to Content/ConvaiReallusion/

• Locate and assign the ConvaiReallusion Animation Blueprint to your character’s Skeletal Mesh

This blueprint ensures that your Reallusion character plays proper idle/talking animations in sync with Convai interactions.

• Refer to the tutorial for this step: [10:12 – 12:48]

---

4. Add FaceSync for Lipsync

To enable lipsync:

• Add the FaceSync component to your character’s Blueprint

• See how in the same video: [12:48 – 12:56]

---

5. Set Correct Rotation

Reallusion characters typically face the wrong direction by default. Fix this by:

• Opening the character Blueprint

• Selecting the SkeletalMesh component

• Set the Z Rotation to -90 in the Details panel

---

6. Prepare Files for Upload

1. Go to: Plugins/<random code> Content/ (e.g., Plugins/AHK3LNKVC7FZA3I5JG3V Content/)

2. Drag and Move both of the following folders into this directory:

   • Your character’s folder (containing the Blueprint and animations)

   • Content/ConvaiReallusion/ (contains the animation blueprint)

   • The final structure should mirror what’s shown in the screenshot.

This folder determines what gets packaged and uploaded. Make sure everything is placed correctly.

---

7. Open the AssetUploader Tool

• Navigate to Content/Editor/AssetUploader

• Right-click and select Run Editor Utility Widget

---

8. Select the Character Asset

• Navigate to Plugins/<random code> Content/YourCharacterFolder/

• Select your character’s Blueprint Class

• Then, in the Asset Uploader window, click Pick Asset

---

9. Capture a Thumbnail

Click Capture Thumbnail to create a preview image that will appear in Avatar Studio.

---

10. Verify Before Upload

Before uploading, do a quick functional test:

1. Drag the character into your Level

2. Select it and locate the BP_ConvaiChatbotComponent in the Details panel

3. Paste in a test Character ID

4. Press Play and verify:

   • Animation is working

   • Lipsync is functioning

   • Character is correctly positioned and oriented

---

11. Upload the Avatar

• In the Asset Uploader, click Create Asset

• This triggers:

  • Packaging the asset for Win64

  • Uploading to Avatar Studio

Monitor the Output Log:

• Wait for Package completed

• Then look for Uploaded Asset

If there’s an error during packaging, check the logs and share them on the Convai Developer Forum for support.

To delete a previously uploaded asset, open AssetUploader and click Delete.

Accessing the Avatar

1. Visit Avatar Studio

2. Go to Upload Your Custom Avatar

3. Your Reallusion character will now be available for selection and use
