I've played with that shader (if its the one I'm thinkng of) and it DOES look awesome - just double cam and shaders kill my FPS something horrid - lame PC - but in a way its good as I really try to keep using techniques where my slow machine will run the game ok - therefore other machines - should do awesome - in theory
That's why I'm straying from double cam stuff - but I should probably in the end add it and make it an option - like NO SHADERS, SHADERS, Advanced Graphics etc.
I'm still looking for a decent CAUSTICS shader and a DECENT "texture a plain and it looks pretty decent" water shader.
I found one that does cool waves - but from far off - the color "rainbow" it wiggles only covers a portion of the plain - and its rather blank in other parts. the parts where you see color variations look AWESOME - but then you hit parts where you can't discern the waves becuse there isn't enough contrast between UPwave color and a "down wave" color.
Maybe I'll try tweaking it some more now that I'm starting to get a SMALL incling about how they work.
