It's nice when the day comes when you feel like doing what you thought about for weeks. In my game the player's goggles sometimes get covered in supernatural green vomit. The vomit overlay can be created digitally but this is more fun - pesto sauce, splashed onto plexiglass with blue background that will be made transparent. Shot with an old EOS 60d with 60mm macro lens. Probably a phone cam would do, but who knows, maybe using proper equipment will give me something extra.
The downside is that open jar of pesto slowly creeped its way into my nose and now I feel kind of ill.
I forgot to post ingame results, here are current variants. Will need some more touches to make it look good. Also I'm thinking of a shader to make it dark if facing away from sun and translucent if not, and perhaps a shifting focal blur. #vomit
