Arnold vs. V-Ray (significant difference)

The Arnold render took 1min 41 secs and V-Ray 11min 38sec. Also note: I am a lighting TD and have been working with V-Ray for over 3 years in production. I have V-Ray in the DMC workflow using QMC GI with 3 bounces and 8 subdivs (default). Arnold is also at 3 diffuse bounces.

Arnold Interior Test (classroom)

So, the aiSkyDome light shader uses multiple importance sampling and renders better quality than just area lights at the window entrance with directional light.

My settings here on my home machine (Mac Pro 1.1 - Quad Core)

Intel(R) Xeon(R) CPU            5150  @ 2.66GHz

 (cat /proc/cpuinfo)

home machine My settings are:
aiSkyDomeLight samples: 6
AA samples: 8
GI (diffuse) samples: 8
Glossy samples: 5

and my diffuse bounces are at 2.


The render took 7.8 hrs.

I am looking into optimizing my settings :]

Diffuse to diffuse path tracing is almost as bad as glossy (specular) to glossy (specular) path tracing.
