For this comparison I used a PC configured as follows:
Motherboard: MSI Z77 g80
Hd: 256gb SSD 840 pro, + Seagate 1 tb, and ramdisk from 6gb of which are temporary files Poser
Video Card: MSI GTX 660 TI 3gb
S.O. Windows 7 x64
Software Used: Poser Pro 2012, Relaity 3.0 and LuxRender, and Octane Octane plugin for Poser.
The model used is Daz3d Michael 4 with a texture skinsuit, created by me, cloak and boots of Goldenage suit of Joequick, lights, basic Poser Pro 2012.
For the render I tried to use the three rendering engines, the most high.
For Poser I used these values: [link]
For Octane plugin I used: environment = daylight, kernel = pmc, gamma 1.2, autofocus, alphashadows, alphachannel and keep_environment = enabled
Reality for 3.0 I used alphachannel enabled, use Lux GPU acceleration = enabled,
Scene configuration = Photo map, with the default values
The duration of the render was:
Poser Pro = 45 min
Octane = 47 min
Reality 3.0 = 1 h
The results you can see them in this picture: [link]
My considerations are, for this first test with a simple model, I think Octane and Reality 3.0 is higher than the engine especially with firefly lights and texture of the skin, between the two honestly do not know what I seem to prefer both excellent. The choice of the winner would do based on price as offered in Reality 3.0 is approximately 30 euros and LuxRender is free, while Octane render with plugi for Poser is over 200 euro.
Firefly, he loses the big confrontation, his render is artificial and plastic.
Now I'm waiting your opinions and considerations, including the settings for the render.
Thank you for your attention.
