Ky Lane Posted September 28, 2008 Share Posted September 28, 2008 Hey guys, Trying to make a water shader for coastal water, so that the density of the water dictates its translucency and color (ie, shallow water is transparent and clear, deeper water is opaque and blue). Any tips? Link to comment Share on other sites More sharing options...
SandmanNinja Posted September 29, 2008 Share Posted September 29, 2008 some sort of falloff map? Link to comment Share on other sites More sharing options...
shaneis Posted September 29, 2008 Share Posted September 29, 2008 Either use a ramp in the refraction colour slot (white to blue) or for a more accurate approach, use a refraction falloff distance (value set for shallow depth), you'll need to model the sea bed.

Ky Lane Posted September 29, 2008 Author Share Posted September 29, 2008 Well Im hoping itll go to opaque before then. Its going to be pretty murky water (not a polynesian island resort) so Ill have a play today with that idea. Was so much easier in Vray, but you get that. I did this in Vray in like 10 mins.. http://au.youtube.com/watch?v=v1oTnY1UzJ8 Link to comment Share on other sites More sharing options...
shaneis Posted September 29, 2008 Share Posted September 29, 2008 It's just as easy in mentalRay. Apply A&D material, IoR to 1.33, transparency 1.0, refraction falloff colour to "murky" colour, falloff distance = depth of water where you want it to start going murky, fresnel "on". As always, check with Zap... http://mentalraytips.blogspot.com/2007_06_01_archive.html Link to comment Share on other sites More sharing options...
Spacelord Posted September 29, 2008 Share Posted September 29, 2008 Hi Ky, Have you tried the water promaterial ? It has some good presets do get that attenuation depth. Or you could just use the A&D material and adjust the refraction max distance. cheers Link to comment Share on other sites More sharing options...

Im just softselecting the riverbed and dropping it down, but the water that intersects still forms polygon edges which look terrible. Hoping to get it to gradually appear reflective/refractive to eliminate that, and Ill add some edge foam in PS. Link to comment Share on other sites More sharing options...
Spacelord Posted September 29, 2008 Share Posted September 29, 2008 Try a displacement map for your river bed, it wouldn't need to much detail so you can low subdiv's or turbo smooth. I guess that would add to many poly's for land of that scale. cheers Link to comment Share on other sites More sharing options...
