After seeing the talk of Matt Nava (Abzu) at GDC 2017, I've tried to redo the shader of the fish that he demonstrate at the beginning of its video.
The job had been quite straight-forward thanks to the shader system of Godot.
- code is available under MIT license: https://github.com/frankiezafe/Fish-shader
- demo video is avaible on peertube (unfortunatly, the embed is not working here): https://peertube.mastodon.host/videos/watch/26b0cb51-dcbf-4bf4-ab6d-557b3d6718be
I hope this could help community!
Enjoy
