No it really does work correctly, I was surprised myself how well. The previous model didn't (as good at all).

Of course, both get dimmer but not at same ratio which you can compare when you compensate exposure (and normalize it).
When comparing to photos or things you remember visually, you have to account for all the variables that happen. Dynamic range (of your eyes or camera), post-production, clouds in the sky, architecture & nature occluding and bouncing light, etc.

Right now, minus the existence of cloud simulation within the Sky model itself, it replicates the light almost exactly to reality.

Good to know your opinion. Thanks.
I'm taking artistic license in that respect then.

Absolutely, so am I :- ). And photographers :- ). Like.. how popular did Sky Replacement "A.I" got in last year? There is Luminar,etc. so many apps. Even before that, EV filters, Polariser filters, Lens coating, etc.. it all contribute so vastly to how we perceive skies in photography.

In terms of light (&shadows) cast, until Sky models have Cloud simulation, you have to change all aspects (size, color, intensity) in artistic way to account for how sun would get diffused behind clouds. Or use HDRi.

I feel like in few years we'll get to that point at as well. Tools like Terragen were always trying to integrate the Sky models in such way.

I think you should rename Volume Effect to Snoop Dogg Effect, just kidding.
I'm not sure how to use this VE with interior scenes.

It's not an interior effect tbh - for that, the full volumetric material (Global, or on an object) would be the correct solution. This one is definitely intended as the haze and aerial perspective seen across long distances while outdoors.

Yeah, got it, thank you.
But I had hoped this feature will work with all scene (it's so quick and lean result)

Testing the RC4 to check if the Magenta tint is gone. After a quick test in a simple scene, the same I used to test RC3, the issue seems to have improved a lot, but it isn´t fully gone. Maybe this is too subjective. Let me show an example:
RC3 vs RC4 comparison at Turbnidity 4: the improvement is massive.
RC3 vs RC4 at Turbidity 6 (or anything above 4.5), and the improvement is noticeable but still looking a bit weird to me. You can check the refraction pass to see how those glass surfaces are tinted when they shouldn´t, right?

Can you just increase strength of the effect at low turbidity and get same result (minus magenta tint)?

I mean, get denser "fog".

After a few minutes testing the Fog with RC4, I noticed that, at Turbidity=2, increasing the Volume Effect multiplier not only makes the Fof effect denser, but produces unexpected results, like bands within the Zdepth range that are more dense and more heavily tinted and other areas that are less dense. I´m not sure what is happening, but doesn´t look like a natural effect to my eyes. I will post examples as soon as possible.

Here you can check a simple comparison, same Turbidity (=2) for all, same altitute (=0) and just changing the multiplier of Volume effect multiplier.

JulioCayetano, please use this topic for discussions about new haze. I moved related messages from daily builds topic here.

P.S. i also find that haze in RC4 is still a bit too pink in certain situations, but it's miles better than it was before.

It looks kind of right to me, but I don't know what should be the ground truth as reference to judge by :- ).

But at least it doesn't have pinkish tint.

Test with new Aerial Pespective. No Postproduction, direct render VFB.
Nice and fast effects with this new implementation.
Thanks

Hi. I'm testing the new Sky, and having a problem. When using the new volume effect together with VDB-skies, I'm getting a purple box around the skies.

Is this a known issue, and are there any workarounds?

Uploaded two images showing the problem.

Yes, known issue afaik - the new Vol Effect replaces any other sort of volumes for now, and adding volumes into the scene (eg OpenVDB, or perhaps even Vol Mat) won't render correctly.

Thanks. Not great news, but at least I now know what not to do :)

Best regards
