Material Request

[Meelis]

Hi

I have been searching for measured absorption and dispersion data for some gemstones.
Maybe u have some.

But some of theme are uniaxial crystals if i remember correctly.

moonstone
roze quarts
lapis lazuli
turquoise

Last 2 in list can be simulated with phong material but how about 1st 2 materials.

I think i soo some 3D shader that varies the absorption or scattering in medium, or what was it.
Can u point me the threat?

Thanks in advance

Thanks dakiru,
i didn't find absorption that i was looking for but there was a lot of other very useful info i can use,
like dispersion.
