##### Registering a custom camera with the Cesium Camera Manager. A reference to the camera manager and the camera id are saved for later.
##### Updating the custom camera, referencing it using the camera id saved earlier.
And here’s an example of using it to fix aspect ratio problems when using the Movie Render Queue:
I’ve never actually tried myself to use the CesiumCameraManager to deal with Movie Render Queue aspect ratio problems (though Nithin did when he first added the feature), so I thought I’d try it. There were some unexpected gotchas, but it worked well enough in the end. Here’s what I did.
First I added a new Level Sequence and added a Cine Camera Actor to it. I set up a simple flight for the camera with two keypoints. Rendering with the Movie Render Queue now works fine, because the default Cine…
