We have been using some of the Corona 7 daily builds in some of our latest production archviz projects. We are very happy in general with all the nice new Corona 7 features, like the PhysicalMtl, etc. All dailies have been pretty stable for us during these last weeks.
I have just tried the new Atmospheric perspective effect in one of our current complex exterior scenes (urban situation). I find the effect to be really nice, fast to render and effective, thanks a lot for the hard work! However, I´ve experienced some weird behaviours, something like a strong Magenta tint, while tweaking the turbidity values. The most curious thing is that it is super visible through reftactions on glass surfaces. I´m a bit confused, not sure what is happening here. Please find attached some crop redners of one of the shots. I´m using a default CoronaSun and the new "improved" Sky model, with everything by default, except from:
-Altutude: 40m
-Volume effect: 1.5
-Turbidity: variable from 2 to 6 (read each file name to see value)

I'm seeing the same thing, anything above 3.5 turbidity seems to add a really strong magenta tint. Also the altitude setting, when the tooltip refers to 'observer altitude' - not quite sure what this is referring to or how to implement it correctly for the correct effect
Flavius:
The crashes with Intel Denoiser are still a problem. Only now I had time to send the scene on your private uploader. On low resolution it works(720px or so), but on higher resolution(try 3000px) it crashes. It happens in multiple scenes. Thanks!
EDIT : Rowan Already answered this. Thanks again.

Just to add to this, I think it would be worth while for a dedicated helpdesk article on using the aerial perspective and what effect the settings can have, I'm seeing some quite heavy colour shifts just from changing the altitude value, currently feels like it's going to take quite a lot of trial and error fiddling with turbidity and altitidue to get the right effect. Green and Magenta tints are really obvious in different parts of the image depending on what you change. For example, 1.5m altitude has relatively neutral haze, but magenta in higher up shadow areas, change the altitude to 10m, the magenta is more subtle but the haze is now shifted heavily towards green/yellow, change to 25m and the colours swap over. And it gets weirder if you throw turbidity changes into the mix too. I don't currently have time to render examples etc, but will if I get a chance

I just wanted to point out again, that the most weird thing that I found while playing a lot with all parameters is the heavy refraction tint seen on cars and facades window glass surfaces. If you check my Refraction Pass iamge, you will notice that most of the heavy Magenta Tint the beauty result has is coming from the refraction of those elements. This really doesn´t make sense in my head, atmospheric perspective effect should not be stronger inside cars and rooms than outside, right?

Hi,
Can you share this scene with us? Instructions on how to do so can be found in my signature.
Thanks,
Rowan
