water/underwater shader preview v0.99

Last crawled date: 8 years, 2 months ago

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:http://www.youtube.com/watch?v=UkskiSza4p0If 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 modelrefraction with chromatic aberrationprojected caustics on geometry from the water surface based on normalsseamless transition to underwater (no fake fog added)accurate water volume with light scatteringview and light ray color extinction based on water color and sunlightsimple coastline detection based on terrain`s height-mapdoes not yet feature:displaced water geometryunderwater particlesunderwater light rays from causticsshoreline behaviorsSky 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.Latest Change on 2013/06/24, 20:02:17Updated blend file
