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 :P
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 :D

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 ;)

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. :lol: :wink:

Tested the scene too.
Bidir MLT, a bit over 6000 spp. 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...

Yes, that's probably the reason.

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:

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]

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.
