For the live service element of Halo: Infinite, one of my biggest projects was building our database of images for the over 2000 pieces of armor, weapon, and vehicle customizations offered in multiplayer. I contributed by developing lighting kits and capture templates for each category, handling the capture process, cropping and compositing the final outputs for publishing.
I also built my own tools on top of existing engine functionality to automate the workflow of creating capture configurations and processing images to reduce what would be weeks of manual work down to only a few days.
