below the video of how we created the fischer bottle,  hope you like fast forwarding!!!
one of many tricks in our effort to reproduce in the best way possible the anglyphs of each bottle and then implement them in our cgi workflow

a good way to kill the refractions when you want to see olny shadow details is to spray paint the bottle
thank you for watching !!!
