Step 7 - Add a Cine Camera Actor

4min

Before a Composure compositing stack can be built a CineCameraActor first needs to be added to the scene. Do this by locating it within the "Place Actors" panel and drag-dropping into the level.

Ensure that a CineCamera actor and not a basic Camera actor is used.

Unreal 5.1 Changes

From 5.1 it is now required to add a separate "Lens" component to the cine camera for lens distortion to be handled, this is shown below

Once the camera has been created it needs to be able to receive the tracking data from Ncam Reality which is made available through LiveLink. To do this, select the newly created camera, click "Add" to add a new component and create a Live Link Controller.

Locate the new LiveLinkComponentController within the Cine Camera's list of components and set it's "Subject Representation" to "NcamLens". The NcamLens LiveLink subject streams all of the camera tracking data required to move the camera in addition to the lens model parameters that are needed by the lens distortion plug-in.

Unreal 5.1 Changes

Epic added the "lens" component in Unreal 5.1 for handling lens distortion on cinecameras. Previously, this was all managed inside the Live link Controller

The lens component allows for distortion to be applied either from a static lens file or streamed in live from livelink tracking data. The latter is how it should be configured when using Ncam

Add a Lens component to the cinecamera (a live link controller must be added as well)

Ensure the settings on the lens controller are configured to receive tracking data from a live link source and not from a lens file
