Cornell-box test scene need someone to render it ...

Psor: Just to say the "Why do you care" was not ment as rude
And the other thing is, you are completly right, i think the same way aswell i use the render engine i feel fits me best
Planning to buy maxwell soon tough, but will defently not stop using indigo, i must have the biggest "wip" topic here
And the indigo renders posted in the maxwell forum, dosnt serve indigo's right, luckly for me i am a multi fan boy, i like all unbiased engines

[lycium]

psor, i'm not trying to "start something" with you either, and i think we're saying the same thing - such comparisons will always be clueless sausage fests (the mac vs pc debate is the same). too much bias in discussion of unbiased renderers

[psor]

Lets do something else guys!

Stop talking and start rendering

[psor]

Stop talking and start rendering

Quoted for agreement. Fortunately I'm already playing with the material editor for some time
and since I'm using an unbiased renderer I've some spare time that I spend doing something
else ie reading topics.

Tested the scene too.
Bidir MLT, a bit over 6000 spp. I see no dark edges?

[Zom-B]

I see no dark edges?

The reason why some edges appear in the maxwell forum test is simply by using a "lowPoly" sphere and not the sphere primitive for a perfect round shape...

[suvakas]

Yes, that's probably the reason.

Even a cube can be subdivided

I also rendered one with the latest Luxrender v0.6 Final.
It took 11 hours on 8 cores and reached 4600 S/px using metropolis sampler + bidir. And it's still not clean. I must admit, that I was expecting a bit better results from Lux. It also has this black ring around the glass sphere.

Ps. My Indigo image took 9 hours on 4 cores to reach 6000 spp.

Here's the Lux image:

[psor]

Ufff, ... nine hours is still a lot! Quite more then I did expect. What settings did you use
for the lux rendering? I mean how many bounces etc. for bidir and what kinda MLT settings.

I have no idea when the Indigo image was clean. I just ran it over night and it showed 9 hours when I closed it. Usually 3000 spp should be enough.

Here are my Lux settings:

Code: Select all

PixelFilter "mitchell"
   "float B" [0.750000]
   "float C" [0.125000]

Sampler "metropolis"
   "float largemutationprob" [0.400000]

SurfaceIntegrator "bidirectional"
   "integer eyedepth" [16]
   "integer lightdepth" [16]

[CTZn]

How much does the depth settings impact lux ? I'm asking because at 2 pow 16 (65k) it is much more than Indigo default (10k iirc). If I'm understanding them correctly, 13 or 14 would be closer.

Also I don't know how Indigo is managing the one parameter between the two directions, ie dunno if it is per sampling direction (for each of light>eye and eye>light) or for both alltogether.

[jotero]

hello all

Here is my final version of the Cornellbox 2! "MLT Bidirectional"

The time is not so important to me.
