Quote - So how does one go about using it with Poser? Is there a plug in or a exporter for the renderer?

To render in Octane, you first must export the entire scene as an OBJ, then you can import that into Octane and assign your materials there.

And no, it's not free. It does have a Demo that is NOT time limited, only locked resolution, and image export is disabled. But you can always take a screenshot and paste it into Photoshop or something to crop out your rendered image.

Edit: The plug-ins for Octane from other software is for animation. If a program can exports to OBJ, then you can use Octane to render stills.

Just remember, Octane requires an Nvidia card, as it's fully GPU rendering. I have dual 9800 GT's so it's fairly fast for most renders. All the ones I did of the Arc were under 5 minutes, usually around 3 to 3 and a half tho.
