What's the purpose?

Hey everyone.

Does anyone happen to know what the CesiumCreditSystem and CesiumCreditSystem does? Just wondering what exactly they do, as I don’t happen to find a documentation.

Hi @LanceCGI,

CesiumCreditSystem is responsible for the attributions of any data loaded by Cesium for Unreal. These attributions are displayed either as on-screen text at the bottom of the screen, or as entries in the “Data Attribution” panel.

More details in the PR that added it:

And here’s an example of using it to fix aspect ratio problems when using the Movie Render Queue:

Tiles not loading at edge of render area

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…
