Does the denoiser even work with BidirVM, have you tested it?
Not yet tested, just an assumption (if it doesn't work I'd use Photoshop).
First I'm going to learn about the engines and samplers before moving on to stuff like the denoiser...

But with BiDirVM+random taking hours to converge it's not that useful anyways, rather Path+metropolis which can be openCL accelerated.
Also BiDirVM+metropolis works fine on another file (no runaway brightness there).

I might open a BiDirVM thread to collect experiences there.

This looks totally cool!

Somehow you managed to get some fierce aesthetics out of a flawed engine :D

I don't understand all your settings but will have a closer look.
