Hey there,
I was wondering if there is a certain workflow to achieve realistic results with a sea water shader. I am trying to create the transparent-feel that sea water has in small depths where it meets the sand.
Is there a way to use the usual "max distance" options for reflection & refraction in the current Corona build.
If not is there an alternative?
Current shader
no-diffuse
reflection ior 1,33 glossiness 90%
refreaction ior 1,33 glossiness 100%
layered noise displacement
Geometry
simple plane
Thank you in advance

Best way for anything that "absorbs more the greater the amount of material light has to pass through" is the Absorption option in the Volumetric settings for the material (e.g. glass that gets darker / more strongly colored in thicker areas, liquids that do the same, etc.)
There's info over on https://coronarenderer.freshdesk.com/support/solutions/articles/5000515622-how-to-set-up-realistic-glass-metal-materials (https://coronarenderer.freshdesk.com/support/solutions/articles/5000515622-how-to-set-up-realistic-glass-metal-materials) for an example of glass (same principle for water) - updated the link to the correct page!. Hope this helps!

There's also a guide for C4D materials that includes water and glass with volumetric absorption:

Thank you for your fast replies!
I did a lot of testing with "Volume" yesterday and I think I am close to achieving the desired effect.
I am going to post my results as soon as I can after I organise them a bit. I think many would find them helpful.
Cheers!
