Well, nothing wrong happens when I export image to the frame buffer or to Photoshop/After Effects... it's the same as the Octane's viewport one (that's a start !)
My only concern is actually to avoid post processing and I would like to have "correct colors" showing up in the viewport :
As you can see in my first screenshot, all the colors are washed out in comparaison to the Max Viewport / Material editor / Diffuse Info pass etc...
I'm sorry if that's unclear, my english is not my mother tongue
