Hmm, alright, if you’re confident sculpting is the better way to go I’ll stick with it, it just really seems though that if you want “physically” realistic wrinkles in every-day, ordinary objects, the physics engine ought to be able to assist you.
Another problem is there’s not always reference material for what wrinkles “should” look like at your camera’s angle with your lighting with your stack of physics positioned how they are, so if you’re eye-balling it, it’s potentially less than believable.
