Tom,
Here i am posting the last render I did with my version of the material.
It is not totally right, but is the best I could do up to now.
I do not like that the material is NOT tottally transparent, and I do not like the saturated cyan colour, since it should be white in my opinion.
I have to experiment more with the textures.
I tried the scene that you sent me, and it worked ok, because the object with the central light (that covers the ball) was switched off.
(The name of the object is Light_03)
As soon as I switched it on, I experienced the blocking problem described previously.
That was the original reason to uncheck the box Hidden to global illumination, as seen here:
This was Zdeno discovery!
Here I am pasting image again with the previous results:
The lower image shows the blocking problem I am talking about.
You can see that the first and second images of this series, shows one of the lights at each time, but the problem appears when they all are on.
Perhaps this is a more complex problem than just a material. It seems that there are other unknown factors fooling us.
Anyway I thank you for your time, and patience. I am having fun, and I have learned a new thing too:
(I can have fun because this is not a commercial work, and i have no deadline)
You wrote: However, you may fail if you attempt to try creating it from scratch because, I didn't tell something very important, yet. The trasnmittance texture has pure black pixels which is not friendly with this trick because, those pixels will block the light on some parts of the texture. In order to avoid it, use RGB Clamp under texture picker. See, it's now 1 to 255 instead of 0 to 255.
I was not aware of this RGB Clamp, and I found it very interesting...
I wonder if this problem was solved in Maxwell V2.x...
Can you test it, switching that central light on?
(the name of the object is Light_03)
This could help me decide to upgrade...
or not
Sincerely Yours
Ernesto
