I ran into a problem one time when i tried editing a model that had some modification already, i was just wondering if you have to start on a unedited character to do edits or continue on a model that has been changed already.
From what i know it shouldn't matter at all, i worked with a pre-edited Krystal model before and i could easily edit stuff i wanted from that model. So you could safely edit it, just make a backup file before starting.
Thanks man, appreciate it. ;D
