DoF & MB noise

[Stan_But]

Looks like you lost the DOF somewhere
I guess somewhere in the Custom bokeh

borisquezadaa, this is a very hard scene. Not only for Corona, but I think also for VRay, MR etc..
We have to admit (and Ondra also) That Corona isn't optimized to render this scene.

Indeed, the DOF makes them impossible. Just checking the SamplerRate on vray side it shows a real nigthmare.
And yes, the custom bokeh was there to "reduce" the dificult dofness... XD.

I totally gave up. This is not possible yet (in reasonable time) and i really try. XD.
Fun to play with do.

I had your same conclusion with my old thread.
But my scene wasn't so strong as yours ;-)

Is this scene available for download somewhere?

In first post You'll find initial scene.

I think you need to keep it in the Signature ))

Done :)

Hope someone find a solution. Or may be even Ondra will have a look at this topic and clear some things.

AA, MB and DOF are all sampled once for every camera ray, I would keep GI/AA and lights mult. to minimum allowed as they are sampled per each ray, reduce the `Max Sample Intensity` and maybe use a higher internal resolution with a more blurry filter, but Pavel you do have a hard example to sample without any biased approximations.

From the developers perspective, I think such mixed AA effects could be sampled better, if there was a way to increase the camera ray samples per object, a naive example would be, if the first ray hits a bbox of an object with motion blur, than throw more samples only to that object by a factor of userDefinedValue.
