I was one of the very small handful of lighting artists that did reflection work across our open world environment on Zeta Halo. I did exterior work on around half of the exterior environments, and also did interior reflection work in most of the banished interior structures. Here's a small collection of images from various exteriors I did reflection work for, captured at a few various times of day.
Contains lots of work from various other artists as well across multiple teams.
Brandon Habib assisted in doing cube map work in the open world.
