Just finished this on Steam, As a unity dev I suspected it would be possible to achieve this look in Unity but I was fully onboard with assuming it was unreal I'm ashamed to admit. I can't believe did the thing that everyone else has been doing for years! I made assumptions about Unity's graphics!
Would love to see any dev vids from you on your Youtube, from PBR setup, the way you block out levels to your thoughts on keeping a "walking sim" entertaining.
