colors of sss are like washed out??

hei suv chek this image....its pure yellow and turn out like white-yellow thing..... here is the exported xml parameters (i have hand edit the exponent value to 5)

Code: Select all

<medium>
			<name>ssssssssss-medium</name>
			<precedence>10</precedence>

			<basic>
				<ior>1.5</ior>
				<cauchy_b_coeff>0.0</cauchy_b_coeff>

				<absorption_coefficient_spectrum>
				<rgb>
				   <rgb>0.0 0.0 25.5</rgb>
				</rgb>
				</absorption_coefficient_spectrum>


				<subsurface_scattering>
					<scattering_coefficient_spectrum>
					   <uniform>
						<value>200.0</value>
					   </uniform>
					</scattering_coefficient_spectrum>

					<phase_function>
					<henyey_greenstein>
					   <g_spectrum>
					   <uniform>
						<value>0.3</value>
					   </uniform>
					   </g_spectrum>
					</henyey_greenstein>
					</phase_function>

				</subsurface_scattering>
			</basic>
		</medium>


		<material>
			<name>ssssssssss</name>
			<glossy_transparent>
				<exponent>5</exponent>
				<internal_medium_name>ssssssssss-medium</internal_medium_name>
			</glossy_transparent>
		</material>

See what happens if you manually increase the absorption by one digit (to 255 instead of 25.5). Maybe it makes the yellow stronger.

yes suv...if i change to 255 i get the real yellow i wont....ouuups...some serius bug here....fix it pleaseeee! :}

here is a quik test.....

[suvakas]

Did you notice, that you can also enter the color values right into those RGB spinners behind the absorbtion color selection? Smaller values produce weaker colors and higher values make more saturated colors. At the moment i use kind of "medium" values there (25.5 instead of strong 255).

What do you think would be the best, should I change those to full integers by default or not?

hhmmm i believe...its more user friendly to have a color picker....and from this picker choose the color wanted....i dont care if the values are reversed for glass or what else....simpli i choose blue and i have blue to my render... thats the point!think about it.....its your desision...but i have never in mint that if i put manually the rgb values in field i get the colos....i think this automaticaly change by the reversed value of indigo uses.....(its realy complex to explain into english...sorry...)but u have understant the main point i think!

[suvakas]

Yes, I get your point.
Ok. I'll change them to full number by default. If someone wants greater accuracy (for some physically correct material or etc), then he can still use the spinners to enter the values manually.

thnx man........and about the exponent thing in glass material?and bump value?are u fix this too?

[suvakas]

Yes, I'll try to remember

thnx u r great........keep it up......im waiting for some update soon!
