Loading SM files - SlightlySimple/FNF-Restructure-Engine GitHub Wiki
SM files are charts used in rhythm games like StepMania and Etterna, and they can be played in Restructure Engine.
SM files usually come in packs, a pack being a folder filled with songs. A "song" in this case is a folder containing the audio, the chart file itself, and sometimes extra images or video.
To load a song pack, create a new folder in your mod called "sm" and place any song packs into it. If done right, every valid song in the pack should show up in the Freeplay menu.
A song will only be considered valid if it's audio is an ogg file. If the song's audio is an mp3 file, it can be converted to ogg with an audio editor such as Audacity.
If your song did not come in a pack, simply make a new one by creating a folder inside the "sm" folder, calling it whatever you want, and placing the song folder inside that.
