Nice one - the subtle CA sells it perfectly.
Re: Silverwings Render Corner
Nice one Raphael!
If you want to push your hardware to the limit and also create some interesting look for the glass try using cauchy b for the glass material (value of lets say 0.001 to 0.003).
This will add the color changes to specular materials that are common for gemstones
Be aware of colored noise for caustics and refractions and longer rendertimes!

I know about the Cauchy B Coeff I used it on the prisms that I made.
To be honest the reason was just that I just was not patient enough with this scene
It sure would give the whole thing a even better look.
Cheers guys and as always thanks for the feedback!
You don´t dream in cryo.

And especially made for Zom-B:
A lot of dispersion

Re: Silverwings Render Corner
Very nice sir! Could you share a little on your camera settings? I've never managed to achieve those nice big bokeh that you have here..
Re: Silverwings Render Corner
He he, dispersion in the dof blur area, you torture your hardware mateSilverwing wrote:And especially made for Zom-B:

Also a great example for the need of "interactive render area", where a user can paint on the image where CPU needs to be focused...

But actually being able to paint where you want to focus would be even cooler.

White Point: E
F-Stop: 8
Aperture Diffraction: ON
Aperture Shape: Image
(I used an image found on google searcvhing for "Bokeh Map")
Tonemapping: Linear
(Pre)Scale: 1
Output as Untonemapped OpenEXR.
What is Bokeh:
The "Bokeh" exists everywhere in your picture except exactly on the focal plane. Its an artifact of the Circle of Confusion. Every part of your picture that is not exactly on the focus plane gets blurred in a circular fashion. The region that you perceive as sharp before and after the focal plane is just the area where the circle of confusion is smaller then one pixel or smaller then your eyes threshold to see it. Depending on the lens and its aperture you have different shapes and internal "densities" of the bokeh shape.
You normally do not see the bokeh in a picture unless in areas of strong contrast.
Lets take a glint inside a glass for example. This is a very small spot that is extremely bright and therefore has an immense contrast compared to the rest of the image (or at least its surrounding area). This lets you see the circle of confusion of that exact point. How big it is and how it looks.
How to get nice Bokeh: (I don´t think its something I did to the camera. It should work well even with the standard settings)
Allow DOF to happen in your scene: Of course to have bokeh you need to have a wide open aperture (small number). Also the scene scale and the lens you use determine the strength of your DOF of course.
Light your scene with contrast, to get a lot of glints and glares (bright areas). Smaller light sources give sharper highlights. Also HDRIs with a high dynamic range are really good. (I am not sure to what extend Colormapping will reduce the effect of seeing bokeh though)
Let it render. You do not see the bokeh straight away. In fact its the last thing that gets clean most of the times. So you have to have at least some patience.
Find the right Bokeh map. Maps that have a bright edge and darker center make the bokeh more visible in the scene. Maps that fade out will make the bokeh almost disapear (really soft). But be careful a strong edge can also make your out of focus areas look really uneven and uncomfortable to look at. (In photography you normally search for lenses with a creamy bokeh that is not distracting)
Thats all I can think of as for now. I hope this helps to get a nice bokeh effect in your renders!

And also yes. It would be great to have the out of focus diamonds a little more refined. You can still see some serious noise going on. But then again... dispersion in out of focus areas is something you do not have every day.
True that. I would love that. Or even a threshold setting where Indigo measures the delta of the pixel changing. If the change is too small (under the threshold) it stops rendering that pixel.Oscar J wrote:https://www.youtube.com/watch?v=J9JTZloMw7U

Re: Silverwings Render Corner
Silverwing: you do know about Indigo's region rendering, right? Save your main render, use the selection tool and make your selection, then start rendering again.
Also - what a resource you are already for this forum.

Re: Silverwings Render Corner
Silverwing thanks for the great explanation! Always a treat for us amateurs to learn from a pro! You are most welcome to the forums!

Re: Silverwings Render Corner
Hi there. With Indigo Renderer 4.0.50 Beta Release bringing us custom GPU ray depth I had to try it out.
Its a rather simple test.
A glass with green absorption medium and Dispersion (Cauchy B of flint-glass)
Rendered for 6 min with a ray depth of 32.
Lit with one HDRI.
Rendered on 3 GTX 1080 Ti
Its still a bit noisy. But I think for the high ray depth, dispersion and the caustics 6min really nice.
I am very satisfied!
Now just bring this into C4D please

How does the 1080 Ti perform?
