Octane for Max VS VrayRT

[gabrielefx]

Hi guys,

this is a funny test to show you how different is the Octane render.
I set the same kernels, bounces and max samples: PT - 16 -14368
In the scene there is a skylight + sun + 6 planar vraylights on the ceiling (one sample) + 2 spherical emitters in the table lamps (100 samples).
All vray materials and lights (except for the sun) where converted with the Octane for Max plugin.
All textures where optimized and instanced.
Octane uses high resolution textures, VrayRT resize all textures at 512x512 pixes with default values. It was impossible to resize all textures scene at 1024x1024, I needed 6GB Teslas.
The two table lamps have an Octane sss mat.
The two scenes have different chairs and the Octane scene was optimized deleting several hidden parts. Because VrayRT resize all textures it can load more polygons.
The Vrayphysical camera has the perspective correction applied. Impossible to do it now in Octane.
The images are a bit photoretouched

Hi Gabriele
It is not impossible to use camera correction with octNe, or at least the same pov.
Only thing you have to do is to create an octane camera snaping it to the vray cam and then align the target with the camera to have the verticals corrected. Then in the modify panel play with the Y value( octane camera options) you can match perfectly.
Cheers

I dont care if its unbiased or so as long as it looks realistic. But I wonder why both scenes are looking so different. Isnt VRay unbiased too?

I would like to see a compairson to Maxwell Render.

Isnt VRay unbiased too?

standard vray is not, but it has an unbiased mode (formerly vray rt). the last time i looked, it lacked a lot common features of the standard engine (proxies!), so i doubt peoply widely use it for production work...

EDIT: i should have taken i little more attention to the topic title

Did you test it on V-Ray CPU as well ?

I suspect, with my Officehardware (Intel Core i7 CPU 3.2 GHz, 6 Cores (12 logical processors), 24GB RAM), this scene, with the same resolution, would have about the same rendertime like your V-Ray RT-Test.

Kind regards
