I created 95% all of the ice and rock pieces in the Imperial Trench on Ilum. The hard surface pieces were kitbashed from existing models found throughout the game.
I created the boss fight platform within the Tomb of Kujet on Dathomir, as well as the doorway, steps, and some ash piles leading into the area.
I also created the wookie prison pods in the Kashyyyk Imperial Refinery.
