 The visual effects supervisor for the season was Mark Kolpack, with Los Angeles-based visual effects company FuseFX the main visual effects vendor. Kevin Lingenfelser started the season focused on 2D supervising, but took over as lead in-house visual effects supervisor after episode eight from David Altenau. Two separate production management and creative teams were established to work on the show, with most of the episodes being worked on concurrently, either two or three at a time.
