Hi

Is there some standard/ updated preview scene for Blender 2.5?
Or is the luxball3 the newest?

Thanks

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

Wow, the luxball looks stunning
Very nice.
edit: can you export a lbm2 or upload the material to the materials db? I'm a bit lazy on fiddling this material into a Blender scene...

I render preview cleaner and then upload to MDB.

When i load lbm2 in blender, the luxblend gui options don't look like what i had set it before exporting to lbm2.
But here it is:

Yes, I had this problem, too.

Here is clean water, i think good for pool water.

Tabulated absorption and Cauchy A/B is from http://refractiveindex.info/

Scattering values are from old Indigo manual "Last updated 25h March 2008" and they are average of all 4 waters:
Mission Bay Surface (1-2) hours / Pacific Ocean Surface (1hour) / Mission Bay 10ft Deep (30min) / Mission Bay 10ft deep (8hours).
But because the absorption of clean water is 12,488099 x lower, maybe it would be better to lower the scattering scale (i didn't).

Blender wasn't able to export to lbm2. I will update soon with better preview.


BTW Rose Quartz is at 1,55 kS/p
after ~ 95 hours looks much better, i think i need more 38 hours to get 2 kS/p (2 work days)

Diamond material, with chromatic dispersion (cauchy's equation)


Luxball5 scene. 2Ks/p, but still very noisy. This material needs a lot of samples to get clear, because of the chromatic dispersion.

Example: Diamond Caustics scene. 12Ks/p

Nice giuliojiang

I managed to get my Rose Quarts cleaner after 321 hours,
I don't recommend to cover large area with that high SSS material.
