Noise pattern should now be much more stable. See attachment - this cannot be unfortunately shown with a single picture

Made a gif for more convenient comparison.
Why does the new mode have less rays/s?
old one was actually rendered by cecofuli on a different machine
This looks promising!!
Very good!!thanks！
great job , thanks , i hope you add velocity pass to corona .
Great
I like the old fashion random noise pattern. I was not advised it it´s a bad thing. lol. 
Looks like filmgrain for me, instead of the fixed pattern.
this combined with the new direct light calculations/lower noise is amazing! Corona just all of a sudden became very viable for animation.
you can still get that if you set the random seed to 0
Wow! This is really amazing, Ondra! O___O
It looks like dust on a screen. What’s a purpose of this improvement? Random noise in animation can be minimized with plugins but static noise seems to be hard to remove.
Oh, thanks for clearing this thing. Dedicated switch is cool in this case.
for animation I can’t think of ANY situation where the old way would be wanted… if you want a camera noise effect you want to do that in post anyway, to have the control…
It makes no sense to me to even keep the option of using the old one, as most people will not know the difference and end up with a way worse solution.
anyway my 2 cents.. love the new changes!
It is. We’re using this method occasionally.
