This is the avatar of a popular DJ in the game Second Life. Made using 157 8k screenshots in a lightroom environment and uses two 2048x2048 resolution materials. This is my first time attempting to retain quality by using 2 materials. A single 2048px image is fine but can result in blurry details. I think the best way to optimize such things for in-game would be to render the materials at 8k, downscale them when exporting from the scanning program to 2048px, open them up in photoshop and resample them to 1024px and save as a jpeg with 10 quality. You go from an original 16mb material to something like 800kb or less.
