" if you start from scratch and make something kinda close, while being specifically ignorant of the actual weights maitreya has, then adjust the weights so that most clothes fit ok, then that's acceptable reverse-engineering."
okay as you already wrote , even if I start from scratch and make something kinda close, while being specifically ignorant of the actual weights maitreya has, can I prove that ? if I develop the mesh body and, to answer customers needs for clothing, re-adjust breast shape, skin weights according to clothing fit (most clothes for maitreya so lets say according to it, not from dev kit, but for ex : trying clothes on body and trial error) so it is acceptable, but if the creator of the mesh body claims "thats infringment" and fill a dmca etc, how can I protect my product? I think , if the creator of mesh body fills a dmca, its hard to prove that "reverse-engineering" or if someone is serious on starting a mesh body project, should they take that risk ?
