Corona sun bug

[Mikhalenko]

Hi all.
For scene lightning I use Corona Sun. Bt in Some areas it make image like "burned". Like on teapot, floor, chair in attachment.
I already try turn off visibility in reflection. It's dosen't help. And this problem appears in differente scene

One of the best news recently!

@Mikhalenko:
In short: activate "thin" in your glass pane material.

Good Luck

Awesome news! The less work-arounds the better. Fully refractive glass in windows with no slowdown or interior darkening, yes please!

well... that wont be the case, no algorithm can do just that and probably never will. It will still not be refractive for GI, and there will be some darkening, but consistent, not localized in highlights

Ok, good to know - so the "best" workflow for interiors will still be thin glass + single sided planes?

That is definitely the fastest - I dont know why people use something else, I think there is exactly zero chance to see the glass refraction (except for bent glass which can be done with bump map in all modes). But we will try to balance things out so it is perfectly usable even in the default non-thin mode.

I am using it for normal solid mesh panes. This way I can just swap the type of glass I want. Also thin glass applied to solid will still yield better reflections, you can stack two offset bumps, you get internal reflection,etc...

Thin plane doesn't make sense to me, irregardless of glass fakeness.

i agree with Juraj, especially here where so many double glazed windows are used, it looks way better to have two sets of glass offset with a bump map to give a nice effect
