x753-More_Suits-X.X.X is required
After launching the game with the mod once, a config file is generated. In this file you can disable individual suits from being loaded, as well as ignore any !less-suits.txt file and attempt to load all suits (which is useful if you have another mod that helps manage lots of suits).
You can add .png files to the moresuits folder to add new suits as long as both the host and clients have the same files.
You can add a .json file in the advanced folder with the same name as your .png file in the moresuits folder to enable additional features like emission. Place additional texture maps in the advanced folder.
