The Opening and Closing scenes are the scenes you'll start and end your marathon on. Because the Intermission scene includes estimated start times of future runs that are based on when the graphic is loaded, it's unwise to start your marathon and sit on your Intermission scene for a long duration. The overlay has a transparent background so that the elements can sit on top of the waveform visualiser. This means you should add your own background into these scenes on the Stream OBS.
Both graphics are identical, albeit one reads "STARTING SOON" and the other reads "STREAM ENDING".
In the top left corner is the Rainwave Music Player, enabled by default but can be disabled in the stuk-nodecg.json config file. Rainwave.cc is an internet radio station that just plays video game music with no interruptions or downtime. STUK is programmed to only play its OC Remix playlist, as these tracks are royalty free and shouldn't raise any copywrite concerns on Twitch or YouTube.
As long as its enabled, Rainwave will play automatically whenever you go to the Intermission, Opening, or Closing scenes - there is no playback control or user input required. The volume can be managed on the Live Audio Monitor, and by default the ON AIR setting is locked so that the music goes out to the stream, but isn't played back to the restreamer - you don't want to hear the Intermission music playing whilst trying to audio balance your next run.
The details are fixed to always display the track name, artist(s), and "OC ReMix via Rainwave.cc" on separate lines. This should not be altered, as it's important to give credit to Rainwave for using their tools. Some tracks do feature a very long artist list; these will simply get cut off at the end of the line should it be too long to fit.
The waveform visualiser isn't built into NodeCG but is a separate source on OBS. If you wish to use your own music player, you'll need to disable Rainwave in the config file, add your music source to the Intermission, Opening, and Closing scenes in OBS, and ensure the waveform visualisers are pointed at those music sources. Be sure to name the Music source with a "♪" to have it show in the Live Audio Monitor. The method to add the track details of your music player to OBS will vary depending on the music player you're using.
The displayed logos, and their size and position vary based on whether forCharity is set to true in the stuk-nodecg.json config file.
