Custom bokeh

[Nekrobul]

How should the mask file look like for the bokeh?

Should it be BW mask where white is bokeh itself?

White shape on black background.
You can use color map to fake some crazy effects like chromatic aberrations.

Thank you.

Always wanted to achive those fancy mirror lens bokeh on renders

[maru]

Yeah, it should be fairly simple with a doughnut-shaped map.

I noticed that most photographers find bokeh from mirror lens to be ugly, while most CG guys think it's very attractive :]

It would be awesome to mimic a twisted bokeh, the one that old russian Helios lens used to produce.

I think it could be replicated, just need to understand the physics behind the proces.

It is requested, so hopefully one day we will get this: https://forum.corona-renderer.com/index.php/topic,4980.0.html

Bertrand shared some bokeh maps last year. His site was kinda slow today.
