Now that we're into the later stages of surfacing, we've agreed to make all major assets 4K resolution textures. Obviously, this is a tremendous upgrade in overall quality, but it's a serious jump up in both rendering time and editing time. I definitely prefer working with lower quality textures while in the pre-final phases because programs load faster so I can get instant feedback on my work. It can be tough to sit and wait for a layer to load its changes and I'm struggling a bit with the transition.
