Using Your Characters

Motion Capture​

Dollars MoCap adds motion capture to your character through two plugins, Live Link and OSC. The OSC plugin includes two methods, Ctrl Rig and IK Rig.

If your version supports Live Link (MONO v.260623 and above, and Unreal Engine 5.3 and above) and you are familiar with Unreal's IK retargeting, we recommend using this method first. For detailed steps, see Using the Live Link Plugin.

If you are not yet familiar with IK retargeting, Epic's official documentation Runtime IK Retargeting is a good place to start.

The following video demonstrates the full workflow using a MetaHuman character.

Using the OSC Plugin​

The OSC plugin provides the following two methods.

Using Ctrl Rig​

Using the Ctrl Rig provided by Dollars MoCap​

If your character is based on the following skeletons, you can use the corresponding Ctrl Rig provided by Dollars MoCap to implement motion capture:

  • MetaHuman (downloaded via Quixel Bridge)
  • MetaHuman (created locally in 5.6 and above)
  • Daz3D Genesis8 & 8.1
  • Character Creator
Customizing Ctrl Rig Based on the Model Skeleton​

If your character does not use the above skeletons, you can make the required Ctrl Rig.

  • VRM Characters
  • Any other characters

Using IK Rig​

You can also use IK Rig to implement motion capture in Unreal Engine 5.4 or later versions.
