hi all, i'm interested on fake dispersion in material glass, i've tried some test, take me your idea and comments about it. first image without dispersion, standard glass

2nd first attempt

3rd less dispersion ...

4th with another objects

tell me your opinion, i would make a tutorial, if needed... Rodluc.

It makes a stunning affect and am very interested in a tutorial

if that is a diamond it would not show the yellow in the ring as much as the picture does.

Pollee i dont remember the IOR of glass i've used, but my test is about the dispersion of light in glass... in few words simulate the rainbow color when light pass in a glass objects... about the diamond i agree with you, with the correct IOR gold dont appear... but this is another story :D

ok, I'm not too sure what you are after but to me the shadows are unreal in the way the light is passing through. IMO the 1st picture feels the best. I feel the elephant in the 2nd & 3rd pic would be more lit if the shadow was that bright. The shadow of the elephant's ear is disturbing in the 2nd & 3rd pic. The ring's shadow doesn't feel right but I don't exactly know why. All in all it is interesting work and fascinating to think about.

Interesting - go on!!!! BTW Anyone knows how to fake sub-surface scattering in V5 Esprit?

please an example... what is a "fake sub-surface scattering in V5 Esprit"

Subsurface scatter is the effect of light penetrating a translucent material and being reflected back, both picking up new color from the material, and affecting the appearance of the material, giving it a subtle 'glow' Human skin is probably the handiest example; the 'glow of health' you get in strong light.

Yep! :)

I understand what you are after now. Thank you Dale. Excuse my ignorance. The color in the glass is interesting and beautiful.

About the SSS: I'm sure the answer to this lies in the function editor, but I'm afraid I won't be the one to find out. The editor is way too complicated for me right now, but I'm learning!
