Cool, are you a TopMod user ?

I have some difficulty to read the shape clearly, like its merging into some transparency... I can see there is sss but my concern is different... you got me ?

Yep, that's TopMod.

Here is the blend to explore: http://butz-e-matic.de/pix/topmod_test3.blend

The transparency is due to my ignorance how all the values effect the new materialsystem.

Here is another version, that is less transparent:

And this might be the material that I used for the 2nd picture (don't remember, if i changed it in the meantime):

Code: Select all

	<medium>
		<name>rubber</name>
		
		<ior>1.0</ior>
		<cauchy_b_coeff>0.0</cauchy_b_coeff>
			<absorption_coefficient_spectrum>
 		<rgb> 
          			  <rgb>0 2 10</rgb> 
        		 </rgb>
			</absorption_coefficient_spectrum>
		<precedence>20</precedence>
		
		<subsurface_scattering>
			      <scattering_coefficient_spectrum> 
         <rgb> 
          			  <rgb>2 12 1</rgb> 
        		 </rgb>
         </scattering_coefficient_spectrum>
			<phase_function>
				<uniform><value>4</value></uniform>
			</phase_function>
		</subsurface_scattering>
	</medium>
	
	<material>
		<name>green</name>

      <specular>
			<transparent>true</transparent>
			<internal_medium_name>rubber</internal_medium_name>
		</specular>

	</material>

That is just beautiful.

Thanks for the code+file, I've found a scene that crashes in wine with those mats, but doesn't with yours.

Cool !!

What does "value" do in the phase function?
