Quote - wimvdb - very impressive quality - can I ask what card you're using? Also, is it possible to alter the RGB values for each texture in Octane? To me the hair has a reddish cast to it which looks mismatched to the scene, I'm wondering if it's possible to make it more neutral. I think I read that Octane has a white balance option but not sure if that's implemented in the plug-in yet - then again, I haven't calibrated my monitor in a while!

I am using the Nvidia GTX680 (main reason is because of VRAM and texture slots)

You can cascade/mix nodes to manipulate textures. There are some limitations compared to firefly, but you can do most things you'd want to do. And there is a white balance option. Besides that, you can set ISO, Gamma, Saturation and camera color preferences which can make quite a difference.

The plugin closely follows the development of the Octane team (1.02 support for the plugin was withing 24 hours, it just needed a recompile)

I use a high-end calibratied monitor (is calibrated every week). I don't see the color deviations which were mentioned, but I do realize that it is also a matter of personal preferences.

The texture which you are using is really an important factor. You can change the color, but not the details. In this picture I was using Danae's Rio texture set. Danae's textures are excellent and work under most light conditions. There are several other popular texture sets which are more difficult, you really have to add texture details to make them interesting at closeup.
