Plugin Types​

Dollars MoCap provides two plugins for Unreal Engine: Live Link and OSC. Choose one based on the Dollars MoCap product you use and your target character.

Recommended

If your Dollars MoCap product supports Live Link, we recommend using it first.

Unreal Engine Versions​

Supports Unreal Engine 5.3 and higher.

OSC-based Plugin​

Supports Unreal Engine 4.26, 4.27, and all 5.X versions.

However, there is an issue with motion capture not functioning after packaging in version 5.0, so it is recommended to use version 5.1 or higher.

Download the Plugin​

Download the Live Link plugin from the Dollars MoCap website.

Copy the Plugin to Your Project​

Unzip the downloaded file, choose the plugin directory that matches your Unreal Engine version, and copy it into the Plugins folder at the root of your project (create the folder first if it does not exist).

After copying, the project structure should look like this,

YourProject/
  Plugins/
    DollarsMoCapLiveLink/

Activate the Plugins​

After opening the project, in Edit > Plugins make sure the following plugins are enabled,

  • Live Link (built into Unreal Engine)
  • Dollars MoCap Live Link (provided by Dollars MoCap)

Restart the project after enabling them.

OSC Plugin​

Download the Plugin​

Download the Unreal plugin and the required Control Rig from the Dollars MoCap website.

Copy the Plugin to Your Project​

Unzip the downloaded file and copy the Dollars directory and the Control Rig directory (here we use UE4 Mannequin as an example) to the Content directory of your project, keeping the Dollars directory structure unchanged.

After opening your project, the file structure should look like below,

warning

Changing the location of the Dollars directory during the initial copy will cause compilation errors.

info

If you wish to change the location of the Dollars directory, open the project, ensure it compiles correctly, and then move the directory within the Unreal Editor.

Activate the Plugins​

In Unreal Engine 4, you need to activate the Ctrl Rig and OSC plugins.

In Unreal Engine 5, since Ctrl Rig is activated by default, you only need to activate OSC.
