To achieve the final look there was a lot of testing involved, such as playing with the balance of hair stiffness. The toupee was created entirely in Houdini using proprietary grooming and simulation tools, which meant that the grooming, simulation and rendering was in one software package, allowing for quicker iterations and more efficient workflows.

You’d think that the biggest challenge on this spot was simulating long hair, but designing a character without legs, arms or a face, from a bunch of hairs that the audience would engage with, and that we could insert into the real world, was the true challenge. We started by creating character design sheets that would outline what the toupee would be able to do. We even explored dynamic animated poses of how the toupee could roll itself up to do a barrel roll or playfully dive through clouds.
