if you want to do a fair comparison algorithm-wise, you should render with progressive pathtracing in vray.

Radiance

Maybe that's because you are working in linear gamma inside Vray

there is currently no reverse gamma correction yet in octane

Can you explain a bit more ?
The output gamma of the viewport is 1
You mean textures are not gamma corrected by default ?

Try to make another example with same gamma in both engine
And like Radiance said, use progressive pathtracing

Good tests

Yeah I thought of that

so play with your imagetexturenode gamma slider.

Seem my bad, when I exported the scene, maps was "corrected" by 3dsmax to gamma 0.45 and that caused dark and barely visible textures, I will render another pic with right textures. And it seems , size of the textures was not the issue for scene to take 460 mb of my vga ram, it was bad export settings.

Will you do a Fryrender as well?

Yep, but fry version will have to wait a bit.

Another one, I'm getting more and more excited , this time gamma 2.2, pathtrace on, render time on the info bar.

I cant stop

I wrote a tutorial about linear workflow in 3dsmax, related though not relevant for octane.

But I see alot of renders here ( on forum in general ) with wrong gamma space.

I'm using the same technique.

yes they are but not RGB values currently...

hello, so dark images can be corrected in Photoshop, for example through the options in the menu Image> Adjusments> Shadows / Highlights ... or in menu Image> Adjusments> Levels. See example
