So in my project Sodor fallout: ham the tank engine I can't find the music to update it to my new system. Any way to search what sprites it is in in?

can you clarify your question? my best guess is to just go through every sprite's sound tab and see if it's there, or export it and upload it whenever you use the audio file

Well, I've looked through almost every sprite but cant seem to find it im asking if there's another way to look.

From what I understand, you are missing a sound. First, make sure your sound file is a MP3 or WAV. If it isn’t, it can’t upload to your project. Once your sons file is in proper format, go to the desired sprite you want to upload your sound. Finally, click “Sounds” click “Upload Sound” then your sound file.
