Looks good. Can you add a feature for letting us load an aperature image like Maxwell Render has? So we can make 5 or 8 sided effects? It is a great feature I used back in my Maxwell days. Maxwell also loads them in "post" without having to re-render the image. But maybe it is technically to much to do.

wow! Nice, thank You.
I Love OctaneRender!

I apologize for this question (hope that noone of octaner's team feels hurted about it....I'm extremely satisfied of Octane and cannot think to work without it )
..what about glazed glass? (blurry refraction & non blurry reflections), for now the only way that I adopted to emulate it is to assign the backface of the glass the blurry glass material and to the other surfaces a completely glossy glass material
...some other good option?
, maybe one day we could have this option implemented directly in the specula shader?
Thanks and Cheers, Paolo

For those wondering why I ask: The lower the fstop number, the shallower the depth of field. The longer the focal length, the shallower the depth of field. For example, an f stop of f1.4 & focal length of 200mm = a very shallow DOF (nice blurry background) whereas an fstop of f16 = very sharp focus. This doesn't necessarily have to tie into exposure either, even though aperture does affect exposure in the physical world. Perhaps 2 separate camera like controls, one for exposure & one for DOF (who says we can't cheat a little bit? LOL)
Idea was to separate exposure and aperture settings. Currently you can change exposure without render restart. If exposure will affect aperture it will restart render too.
That's exactly my point
The exposure controls are already separate in the Imager, are post process, and don't restart the render. My thought was to have the same type of fstop equivalent control for DOF, and see the camera controls themselves evolve into something more in line with the photo camera concept, like using a 50mm lens focal length @ f1.8 or a 200mm focal @ f11 instead of having to break out the math to calculate the equivalent form the existing camera FOV/Focal depth/aperture settings.
This all looks lovely BTW Karba, and I second for bokeh blade/pattern masking. That would rock!

'cheep efects' could be done outiside the program easilly, I gues..but maybe someone else will see the point of having those in Octane. personally think it's worthless. majority of usage is too much exagerated & in real life the effect just says how pour the lence is..after 3rd7th showcase everyone start using this as a must have element of picture, but 9 out of 10 times putting way too much..- having it in post You would have much more flexibility..but I might be wrong =)

Yes I also add it quickly with Photoshop or whatever. But it is an annoying rainbow effect and clients dont like it very much too.

yes can do it outside .. although ,as you said , the real one is based on the lens.. and not all over the picture like most people do ,,,
and yes i agree 100 % your feeling about people using too much of it .,.,it's all about moderation
