How To Use/Quick Start Guide

Project built using Unity 2018+, TextMesh Pro Package Manager, and ARKit plugin. Note ARKit plugin is only required for iOS build of remote. For your convenience, you may want to build the remote from a separate project. For best results use Bitbucket tip of ARKit plugin

This repository uses Git LFS so make sure you have LFS installed to get all the files. Unfortunately this means that the large files are also not included in the "Download ZIP" option on Github, and the example head model, among other assets, will be missing.

iOS Build Setup

1. Setup a new project either from the ARKit plugin project from BitBucket or a new project with the ARKit plugin from the asset store.

2. (Unity 2018.1) Add TextMesh-Pro to the project from Window > Package Manager. The package is added automatically in Unity 2018.2 and above.

3. Add this repo to the project and set the build target to iOS.

4. Setup the iOS build settings for the remote. In Other Settings > Camera Usage Description be sure you add "AR Face Tracking" or something to that effect to the field. Note You may need to set the Target Minimum iOS Version to 11.3 or higher. You may also need to enable Requires ARKit Support Note To use ARkit 2.0 you will need to set ARKIT_2_0 in Other Settings > Scripting Define Symbols* this will be required for any platform you want to use ARKit 2.0 features with.

5. Open Client.scene and on the Client gameobject, set the correct Stream Settings on the Client component for your version of ARKit.

6. When prompted, import TMP Essential Resources for TextMesh Pro

7. Enable "ARKit Uses Facetracking" on UnityARKitPlugin > Resources > UnityARKitPlugIn > ARKitSettings

8. Set Client.scene as your build scene and build the Xcode project.

Editor Animation Setup

Install and Connection Testing

1. Add TextMesh-Pro to your main project or new project from Window > Package Manager.

2. Add this repo to the project. Note You should not need the ARKit plugin to capture animation.

3. To test your connection to the remote, start by opening ../Examples/Scenes/SlothBlendShapes.scene.

4. Be sure your device and editor are on the same network. Launch the app on your device and press play in the editor.

5. Set the Port number on the device to the same Port listed on the Stream Reader component of the Stream Reader game object.

6. Set the IP of the device to one listed in the console debug log.

7. Press Connect on the device. If your face is in view you should now see your expressions driving the character on screen. Note You need to be on the same network and you may have to disable any active VPNs and/or disable firewall(s) on the ports you are using. This may be necessary on your computer and/or on the network. Note Our internal setup was using a dedicated wireless router attached to the editor computer or lighting port to ethernet adaptor.

Known Issues

1. Character Rig Controller does not support Humanoid Avatar for bone animation.

2. Animation Baking does not support Humanoid Avatar for avatar bone animation.

3. Stream source can only connect to a single stream reader.
