Very similar process if not identical, been awhile since I used Classic. There are differences between Reloaded and Classics character models though. They need to be converted unfortunately. I did a basic tutorial as how to get a model (just a cube) in from Blender. Not exactly an amazing model, but it shows you how it's done.
