I had the honor of making Cere's lightsaber and set for Jedi: Survivor. I was responsible for the high poly, low poly, UVs, bakes and textures (Kurt Klockau did the textures for the workbench version). This lightsaber was heavily inspired by the "Boone Kestis" lightsaber concept by Gus Mendonca. The side vents and heavy ring on the heavy lightsaber customization was designed by Amy Fry.
