This is the concept sketch I did for the Tempted Apprentice lightsaber. I started with the Luke Skywalker Return of the Jedi V2 lightsaber, and rearranged its components, and added a few elements of older original trilogy lightsabers.

This is the final in-game set, modeled and textured, and extended to a main-hand saber, shoto saber, and dual saber.

 

These are the final assets in-game, along with the animation and VFX I made for them. I particularly enjoyed making the power level indicators light up and animate. I modeled planes that carried the lighting information not only for the centers of the lights, but the bounced light within the control box bars.
