After three days in development, hopefully it will be worth the wait.
Trained off screenshots of Half Life 2, Counter-Strike Source, and Day of Defeat: Source. This was a fight and a half to get working, but it can gen pretty close to that classic engine look.
Realism is as close as I can get to Source looks, Shiny Anime is built on an anime processor, and the 50 and 100 datasets are tests that make pretty backgrounds.
