Have a read of this fascinating look at how Hasbro research and design their figures, specifically the Star Wars Deluxe Black Series 6″ SDCC Jabba and Salacious Crumb.
No matter which character they’re making a figure of, the team always starts by gathering reference. Usually, that means amassing as many photos of the character and its accessories as possible to ensure film-level accuracy. “Many of the classic archival items are based on image turns rather than 3D scans or renderings [of puppets] since the costumes are delicate and, in most cases, require a person to be in them to capture the images,” Smith says. “Instead we refer back to the many on-set photos, film screen shots, and Lucasfilm-approved reproduction art. In some cases, there are so many images and pieces of reference out there that you start to notice subtle differences in features, accessories, etc. Here we work closely with Lucasfilm to ensure we are replicating the approved, on-canon elements.”
