Corona Physical material has way more noise/fireflies than legacy material

(1/1)

Basshunter:
Has anyone noticed that?

It's very noticeable specially on metals and translucent materials. Maybe this is the reason why my scenes feel so noisy when compared to previous versions. Is there any reason for this?

TomG:
To be honest, doesn't look like a "like-for-like" material set up - the new one is rougher, making it less transparent and more opaque (and rougher refractions in particular require more processing time to clean up). Even if the values are the same, they'd need adjusting in the materials until they are doing the same thing visually.
