Join Steve Caplin for an in-depth discussion in this video About the exercise files, part of Creating 3D Type in Photoshop.
Most tutorial courses come with a load of download material that you can use to replicate the artwork you see being created. This course comes with just one downloadable file, it's a piece of wood, that's because you'll create the main 3-D object, the glass tape. Directly inside Photoshop. This wood is your background, and you don't even need to use this. Pick any background you like. It's your artwork.
