2 - Importing and Preparing the Point Cloud

In order to use a point cloud in UE4 you will first need to import it into the engine. For the purpose of this guide we will want to move around the imported point cloud scan so we will enable collision as well.

  1. Create a new project.

  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.

  4. Right-Click on the Point Cloud in the Content Browser and select Edit .

  5. Click Collison and select Build Collision from the drop down menu.


  6. Place a Player Start above the ground.

  7. Click Play to start Play in Editor mode and move around the imported scan.

Your point cloud has been imported and now has working player collison, feel free to explore your imported scan. As you move around you may find things you want to modify. Next we will go over making simple edits to the point cloud.


3 - Editing the Point Cloud

When working with point clouds you may find that the cloud needs to be modified to meet your needs. You can make changes to your imported cloud by enabling Edit Mode .

  1. Right-Click on the Point Cloud in the Content Browser and select Edit .

  2. Click Edit Mode .

  3. You will need to fully load the point cloud into memory to edit it. When prompted to do so, click Yes .

Once points are edited, collision must be rebuilt.
