Poppi, If you start with V3, then it's derivative. Is it provable? Depends... Do verts line up in key places? Does your .cr2 file contain identical information as the source? Can someone make a good case that you did start with another figure? Then you could be in trouble. There are tests that can be run to compare programatically two meshes for verts and shape. It takes time and effort though, and sometimes it just doesn't pay to do it. Renda does look awfully close to V3 though. The places I'd be doing an eyeball look would be the fingers, feet and toes, face, and hip. The closer these match between the two figures, the more likely there's a problem of this sort.
