Hey NurtNurt,
Here is what I know so far about the camera. You have the typical F to focus on selected Actors. You also have Create Camera Here within the Level Editor Menu. You have other transform commands within the Level Editor Context Menu. So if you aren’t used these already, this may help you achieve your desired cinematic goals. Other commands like Align to Actor, are currently commented out in the source LevelViewportContextMenu.cpp. I was unable to find it linked to a key or button within the source. Looking back at an older Question/Answer, there was a request for an Align To… function. [Request] Align Objects - Mobile - Unreal Engine Forums
