How to fix noise in Bokeh shapes?

[^Lele^]

That's a question for @vlado.
The idea of batching and sorting isn't new (see Hyperion, f.e.), and i was reading a paper i can't recall whom from not a week ago on the blurring of ray directions to improve sampling, so you may be on to something, you clever old chap! .

Old at least

Old at least

if you're old, what must the rest of us say then?

One way to make this easier on the renderer is to make the reflection slightly blurry. I'm thinking of experimenting with automatic adjustment of the glossiness based on the distance to the camera and the defocus amount. This slight change will not be obvious in most cases, but will help to clean up the bokeh faster. The idea is very similar to texture filtering, but applied to reflection glossiness.

Best regards,
Vado

Ooh! Oliver could almost try that now on his silvers with a falloff map using his camera target as it's reference object!

That's a good idea actually. Will try that.

Hmm, since it's a focus plane I wonder would you be better off using a plane and a distance tex?

[^Lele^]

two-pass render: one with the defocus amount RE, used later as repro to drive gloss amounts.
Jesting. ^^

[joconnell]

That's kind of a good point though, almost a shade map pass or LC prepass to guide what the camera is going to see!

[^Lele^]

I was left thinking the vrayInfoTex could maybe have that mode too (after all it is able to mimick nigh any other data RE).
Then it'd be a case of renormalising and plugging.
Not trivial overall, though, and with plenty latitude for mishaps.
Better leave it to Vlado... XD

Well, Lele found the solution in another file. Simply raise Max AA (a lot, I used a value of 1000), and the result will be clean. Also, a LOT longer to render. Anyway, I can live with that.

They look stunning!

Yeah, the kind of shapes that are generated are amazing. Looks totally convincing.
Now, if there is a way to more efficiently sample these bright highlights, I would be happy... If there are scenes needed for research, please tell me, I got tons!

[^Lele^]

Ah! We won't pass on the offer as the time comes, rest assured!

[joconnell]

That's veeeery pretty! Were you using a filter map on your camera settings?
