Thanks Ono!

Very nice!!!

How do you have these caustics, I use the last blendigo v9 beta 8 and indigo v9 beta 9, I don't anderstand the problem

does your water have thickness?
What it *does* have, is far too high absorption

No it's just a plane

Code: Select all

	<medium>
		<name>Material.001</name>
		<precedence>10</precedence>
		<basic>
			<ior>1.5</ior>
			<cauchy_b_coeff>0</cauchy_b_coeff>
			<absorption_coefficient_spectrum>
				<rgb>
					<rgb>0.0272425 0.0272425 0.0272425</rgb>
					<gamma>2.2</gamma>

				</rgb>
			</absorption_coefficient_spectrum>
		</basic>
	</medium>
	<material>
		<name>Material.001</name>
		<specular>
			<transparent>true</transparent>

ok...
lower your gain and make your water a volume
Indigo doesn't like one-layered meshes, especially if they are transparent

[Vanessa07]

Thanks it works fine

[CoolColJ]

your water colour is wrong

use these values and model the water with volume exact to real size
1 unit in Indigo = 1m, so if you use cm in C4D, then set global scale multiplier in the exporter to 0.01 etc

water mesh must go inside the walls

IOR = 1.33

absorption
red 0.35
green 0.1
blue 0.015


scattering - optional
red 0.0007
green 0.002
blue 0.0026

Gamma = 1 for both

and then don't add any bump map to the water mesh and pool surfaces - they slow rendering of caustics a lot!

so you finally found out the correct water material
