Step 3: Add the Camera Actor of your preference

You can select between three ready-to-use Camera Actors.

  1. BP_CT_CameraActor A custom Cinecamera Actor with the appropriate LiveLink controllers and components to enable CameraTwin functionality. This Actor is suitable for all general purposes and Virtual Production setups.

  2. BP_CT_Capture_CameraActor A specialized Camera Actor with a Scene Capture Component suitable for capturing accurate color and ray traced light effects. This Actor is suitable for use with Composure Composition layers\

  3. BP_CT_Plate_CameraActor A specialized Camera Actor with a Image Plate ready to project the Camera Stream inside the scene at a given distance. This Actor is suitable for AR compositions and easy in Scene preview of the video stream.

It is possible to create custom Camera Actor setups specialized for your use-case. We recommend to start from the generic BP_CT_CameraActor and build up your setup.
