Description:

This is an ongoing project of mine with an aim to create a realistic water and underwater shader. Keep in mind this is a work in progress and serves just for demo purposes, I no not really recommend using this as a resource for your own projects. But I do intend in to expand this to become an artist friendly toolkit for those who want to have realistic water scenes in their projects.

video of the shader in action:

If you have any suggestions, comments, or technical issues running the blend, drop me a message in this thread in BlenderArtists forums:

http://www.blenderartists.org/forum/showthread.php?242940-unlimited-planar-reflections-amp-refraction-(update)

The water shader is based on my own observations of water characteristics.

it features:

  • reflection with accurate fresnel refectance model

  • refraction with chromatic aberration

  • projected caustics on geometry from the water surface based on normals

  • seamless transition to underwater (no fake fog added)

  • accurate water volume with light scattering

  • view and light ray color extinction based on water color and sunlight

  • simple coastline detection based on terrain`s height-map

does not yet feature:

  • displaced water geometry

  • underwater particles

  • underwater light rays from caustics

  • shoreline behaviors

Sky model is based on Preetham, but implementation is from Simon Wallner, with a significant (artistic) changes done by myself.

I have also included an overly exaggerated experimental glitter shader and a completely procedural "water droplets on lens" shader.

    Really outstanding!

    I get low fps rate but the look fells really real.

    And that wet effect in the camera... just great!

    Keep up the good work!

    Follow up: I can't believe the framerate this is running at, steady at ~30fps on my reasonably high-end rig... If this is how clean it runs when the code is a mess, can't wait to see what you can crank it up to with some optimizing! Great work!

    Thanks for the sharing!

    It looks very very nice! But unfortunately i can't test it, though i've downloaded it, because i have an issue with glsl (don't really know from what it comes, probably a question of drivers (I'm under linux with the non proprietary nvidia driver)): all object that don't have an image texture do not receive light, and all of them are displayed black (in viewport as in game).

    Anyway, thank you! :)

    This is absolutely outstanding... you seem to be a pro a coding because the integration between python and C++ is perfect. :) Hope to be at your skill level someday!

    This is so beautiful. Even though there is nothing to do here I love to just walk around and enjoy the view. There was an age in URU that has that open atmosphere too.

    This looks great! Is it possible to use things made for the game engine in pre-rendered scenes? And have you managed to get a shore-line behaviour working? I would buy that!
