I am asking this on the forum as I am not sure if it's even a good idea, and if so, then it would be still super low priority. Just an idea:
Super fake sky model, where you can tweak every possible setting to your need:
-halo around sun
-halo intensity
-fake clouds (some noise map which would occlude sun)
-possibility to blend with HDRI - so you can for example load a sunless HDRI and overlay a sun manually wherever you need it
-contrast and other post-processing stuff similar to color correction node
-blurring
This would allow simulation of different weather types which would be currently hard to do.

Aproved

-fake clouds (some noise map which would occlude sun)
How is this supposed to be working?

Good idea.

It would probably look ugly, but it wouldn't have to be visible directly. The purpose of this map would be to generate lighting. The clouds could be done by some simple noise map, which would be overlaid over the sun/sky based on some simple parameters such as size, thresholds, color...
-
Ok, I guess you mean a "virtual" layer between the sky/hdri and your scene which would then be able to cast shadows (since you cannot simply add it on top of the sky). Mhh... not sure if this could be accomplished by a simple map.
-
Actually, mental ray has simplified version of this option for quite a while. http://mentalraytips.blogspot.cz/2007/02/clouds-with-mental-ray-sky.html
Basically, you can map haze parameter (similar to turbidity in corona) of MR physical sky with spherical environment map to get some clouds.
-
This is briliant idea actualy.
About fake clouds i had this plugin instaled called DreamScape. It somehow generates clouds and have number of tweakable parametrs. And it is supported by corona-renderer (only it kills rendertime for some reason) may be those could be merged.
OR - it is better to integrate full Ozone or Vue support.
-
Thumbs up from me for this, definitely. Been trying to figure out how to achieve decent animated cloud cover for some time, with varying levels of success. Something native to Corona would be excellent.
-
Something something. I am not talking about anything fancy. Just a way to generate nice lighting fitting your scene instead of loading a hdri.
-
Interesting... could you somehow alter it to generate dappled shadows on the ground at a visible scale?

Shouldn't that be done by a projection on Sun instead ? I kind of miss such feature because I don't want to swap to direct light to do that.

Quite right, yes. It would need to. This is how we've done it in the past - by using a plane with opacity map on it casting shadows.

E-on Ozone for corona , perhaps !! :D
