Hmm, since it’s a focus plane I wonder would you be better off using a plane and a distance tex?
two-pass render: one with the defocus amount RE, used later as repro to drive gloss amounts. 
Jesting. ^^
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!
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
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!
Ah! We won’t pass on the offer as the time comes, rest assured!
That’s veeeery pretty! Were you using a filter map on your camera settings?
No filter image, it is all standard. I modified the ringing-value a little, that’s it.
