Installation

1. Install the plugin

Close Unreal Editor and place the CAT folder in one of these locations:

<Project>/Plugins/CAT
<Engine>/Engine/Plugins/CAT

2. Open the project

Open the project with Unreal Engine 5.7. Allow Unreal Engine to rebuild the plugin when prompted.

3. Verify dependencies

Open Edit > Plugins and confirm:

  • Customizable Assembly Toolkit is enabled.
  • Enhanced Input is enabled.
  • Water is enabled.

Restart the editor if requested.

4. Confirm the installation

Open the Place Actors panel and search for CAT Assembly Actor.

If the actor is available, continue to the Quick Start.

CAT does not appear

Confirm the engine version and plugin location, then check the first CAT-related message in the Output Log. See Troubleshooting.
