**UPADTED - rendered 14h**
I started a Diamond Caustic dispersion Test, by using this material:
Code: Select all
<material>
<name>diamant</name>
<specular>
<normal_reflectance>0.05</normal_reflectance>
<transparent>true</transparent>
<ior>1.7280</ior>
<cauchy_b_coeff>0.1342</cauchy_b_coeff>
<rgb_absorptivity>0 0 0</rgb_absorptivity>
</specular>
</material>
I found some NK-Data for minerals, but at this Point Indigo doesn't support transparent NK Materials

Any Suggestions?
