In addition to traditional cartoon drawing, Rough Draft Studios often used CGI for fast or complex shots, such as the movement of spaceships, explosions, nebulae, large crowds, and snow scenes. The opening sequence was entirely rendered in CGI. The CGI was rendered at 24 frames per second (as opposed to hand-drawn often done at 12 frames per second) and the lack of artifacts made the animation appear very smooth and fluid. CGI characters looked slightly different due to spatially "cheating" hand-drawn characters by drawing slightly out of proportion or off-perspective features to emphasize traits of the face or body, improving legibility of an expression. PowerAnimator was used to draw the comic-like CGI.
