Step 6 - Add a Camera to the Scene
Note that Workflow Wizard should be run before adding a camera. If it is run afterwards then the camera should be removed and added again.
The Ncam AR Suite includes a number of camera actors that simplify the process of setting up an augmented reality scene. They eliminate the need to build a Composure composite by only requiring that an appropriate camera asset is dragged-and-dropped into the scene.
There are differences between the two versions of the AR Suite plugins which are described below.
Camera Blueprints are no longer provided as part of AR Suite Lite. For compositing when using the Lite plugin it is recommended to use the Composure framework instead.
This is described in the subsequent section
The AR Suite plug-in provides two camera blueprints that use a post-process to correctly combine the video with the Unreal graphics. They're included as a quick way to get an AR scene up and running as quickly as possible. Users can always use the Composure workflow if they require more features.
A camera blueprint just needs to be drag-dropped into the scene. They are located in the "Engine / Plugins / Ncam AR Suite Content / UE Camera / Blueprints" folder.
The Cameras available in the Suite plugin are called:
- NcVirtualStudioCameraBP - Unreal Graphics will be behind the video signal and will only appear when a suitable chroma key has been selected
- NcVirtualOverlayCameraBP - Unreal Graphics will be overlaid over the video signal
Please see the Rendering Features section to see how these cameras differ and for an illustration of what features are available.
