The LiDAR Point Cloud plugin is included with the Unreal Engine, but you must enable it for your Project before you can use it.

  3. Save your project and restart Unreal Engine.

2. Importing the Point Cloud

  1. Create a new project. Use a template that includes a character controller, such as Third Person Template.

  2. Choose the point cloud file you want to import and drag it into the Content Browser.

  3. Drag the point cloud from the Content Browser into the Viewport. This will automatically create an instance of a LidarPointCloudActor and assign your specified cloud to it.

3. Building and Testing Collision

Before you can move around the imported point cloud scan like any other Level, you need to build and enable collision for it.

  1. In the Main Toolbar, click the Modes button, select Lidar Mode.
