Flickering

[Ondra]

It would seem less odd if you would see the source codes - MSI is NOT applied to ideal (glossiness 1) reflections and refractions, but it is applied to everything else.

So, what we need is a "simple" script that change the glossy, for every glass shaders,  from 1.0 to 0.999 (if the glossy parameter is set to 1.0)

[Ondra]

Why? In 99% cases there are no problems with this type of fireflies, but by using this script you would get much worse rendering quality (missing reflections - no luster & brilliance). I can instantly make you version where MIS is applied to ideal glass, but it would hurt the result in most cases.

To avoid this such of flickering in animation, as in the petoboso scene.
But I understand what you want to say us =)

[Ondra]

sure, this can be neat trick if you dont care about quality and want to do animation fast... so put it in your bag of tricks and use it where appropriate, but only there ;)

How about a checkbox next to MSI "apply also to ideal reflections"? Or hidden deeper in devel settings.

I agree to Maru ;-)
