Here are some more test renderings with different settings.
All path traced. Settings not mentioned have not changed.

Yup indeed, won't take long until Oshyan or Matt will join this discussion here.
This should also affect underwater surfaces I'd tend to say, but those work fine with RDM., thus perhaps it might be an over-agressive optimization of the path tracer.

Interesting.

Did you guys try turning on "Ray Trace Everything", out of curiosity?

Yes, I did. No difference.

Hi,

I just installed the latest Frontier4.4.48 and gave the 3 glassplates another try.
Here is the result. Weird. This can`t be right, not?
This is the identical file which gave the top left result in the previous composited picture.
I attached the scene file again if anybody wants to take a look, again.

Huh. Wonder if this explains why my ocean is currently looking very speckled with black dots. Just installed latest frontier before working on the water. Refraction on even the top level don't look right.

WAS

This doesn't look right, especially at MPD 0.6 and AA6, everything is fairly smooth minus caching, but that water is atrocious. Just basic water shader, decay distance at 75. Foam is white so it's only where it's at and shouldn't be effecting this.

Matt

@WAS, What does it look like in previous versions? Could it be the roughness?
Just because milk is white doesn't mean that clouds are made of milk.

Matt

@KlausK, I'll work with your file to fix whatever's causing this. Thanks.

That's a good point. I did up the roughness up to .05, though I swear I do this for ocean water all the time. Could be the sun angle on the reflections. I'm throwing it at my render node tonight which isn't upgraded so I'll know if there is any real difference.

Tangled-Universe

I have had some of these issues as well, but could not reproduce it really.

Matt

This is fixed in v4.4.49 (coming soon).
