Hey Houska,
thanks a lot for your reply.
I actually know the techniques how to reduce antialising on hard contrasting edges.
Been playing around with combination of highlight compression, reducing GI/AA to 4-8, highlight clamping on 4-10, changing image filter,
higher glare intensity... all combined... :)))
Antialiasing gets better...
A pitty that one loses the dynamic in the render.
The other point, which also other users start to notice: somehow the sharpness and details got worse in Corona 4.
Renders look washed out... ( AI denoiser on about 0.5 - 0.7 )
Please have a look at those two renders:
First one rendered with Corona 1.7 - nice clear details & antialiasing.
Rendered around 35 minutes on a 7 year old !!! 4-core i7 3,4 GHZ
Second one rendered with Core 4 Beta... all seems blurry and the metal looks washed out (as mentioned by other users, too)
Rendered around 20 minutes ! on a brand new 8-core Xeon 3,2 GHZ !!! ???
Super odd... since the Xeon is actually 3-4 times faster. And the PC has incomparably better cooling than the old one.
Some of us users have the impression that renders in Core 4 Beta became washed out and AA got much worse, even after lots of passes.
Bad results with same shader & lighting techniques and 3-4 times faster Computer ???
Hard to get my client work done nicely at the moment...
