Milk (regular) optimized

Post by Meelis » Mon Dec 13, 2010 10:18 pm

Hi :)

I made Milk material
At the moment i don't have free time to render good quality preview.
If you can render it, you may upload it under your name to MDB. :wink:

Maybe just noisy. The preview was in path tracing mode, 1000 MNCR.

The milk will get better if live it on table for few weeks :D

MNCR 10000
Supersampling 2
MLT Bidir

Very cool scene Meelis. If you would like, I could render it until it's noise free for you? :)

Thanks :)

Are you shure, it's not that cool as it's slow (+ that ugly shadow on backwall created by emitter plane)
I'm rendering it on network with C2D e4500 2,2 GHz + C2D e7400 2,8 GHz.

I will upload packed indigo scene tomorrow morning (~ 8 hours from now)

Here is update

Here is the unpacked pigs (80,5 MB) and repacked with 7zip (36,1 MB)

Hope it still works

..to me, they look like fireflies.. :?
That's why I asked. Do they go away after further calc time?

..mmmmmhhh..
I guess by that time the "regular noise" should be gone by far...

Maybe i need more super samples than 2. (i need to add ram in slave computer for that)

If more super samples doesn't help i might try:
* I used 0.9 white, so i can go with 0.7
* I should lower SSS uniform value from 500 to 200 maybe.
* Can MNCR 10000 be problem, i go with default 1000

111 h :D

Hmm.. Wasn't there much cleaner SSS in some earlier Indigo builds long long time ago ?
11k samples should be crystal clear. I remember having decent sss with 6k spp. If sss works like this now, then it's not usable at all. Ono? Lyc? Any comments ?

Wow, that's quite a noisy result for such an incredibly long rendertime...

My suggestion is to use MLT path tracing, non-bidir. Bi-dir tries to make many connections inside the SSS medium that don't contribute any light paths, this is somewhat inefficient even if MLT is helping it along.

edit: upon further investigation of the render settings, i suggest to never use gaussian splat or downsize, it's slow and doesn't look as good as fastbox + MN; also, you should prefer circular apertures unless you really want a particular bokeh effect, since rendering with generated apertures is considerably less efficient than circular ones.
