Pretend I don't know anything about models, meshes or formats for a moment. Is it possible or practical to move models available elsewhere into Sins format? The Ironclad converter is good for the last step, but is it possible to convert between model formats to get to that point? I'd like to try some model replacements, but I'm not sure what format these are in or if they're able to be converted to the right format without having 3DS or something.
