I more meant like i found an Avatar and want to build something for it. like a body i want do dress for but strugeling to have a model to work on so deciding to just buy the body, copy bot it. export it from SL, import the model than in i.e. Blender. Do my mesh work with the help of the model and Upload for selling just what i work out. I mean beside i have to get the Model in a way which seems either black nor white it do not sounds that illigal to me.
