The following animations were made completely in unity. The task was to make the HUD UI states more noticeable. I worked on the NOS boost bar, Health, and Speed UI on this screen. The animations below were made directly in unity and provided to the developers as separate animation clips they could use for final implementation into the game.
Car Town Racing - Nos Boost
Car Town Racing - Nos Full (cycled)
Car Town Racing - Health Critical
Here is some footage of the effects in-game. Credit to Pixels for capturing the footage.
