The tanks featured in the game I worked on, “Tanks for Nothing”. Each tank part was designed to fit with the other parts. The Alpha channel in each texture was used to mask out which areas of the tank would change color. I modeled and designed all the parts except for “Chain Lighting” and “Flamethrower”. I only did minor changes to those, they were modeled by team member Jess Cooper. The “Abductor” base has two animated properties; the beam pans across and the lights flash different colors.
