I post my Rose Quartz with:
* tabulated absorption spectra
* procedural textured scattering scale
Also if u like u can play with the scale of procedural texture in LXM file (but 0.025 is good. Values go -10 000 to + 10 000).
"vector scale" [0.025000000372529 0.025000000372529 0.025000000372529]
Belive or not but i can see here nice caustics, close reflective surrounding objects make it cool.
it's just 176 S/p crop from 1280x1280 image (rendered 27 hours on c2d e4500)
I will render the preview to 2000 S/p on c2d e7400 and update the image, if i don't go AFK anytime soon.
Image looks overburned on my older monitor, not on newer monitor.
EDIT updated at 1,55 kS/p
