sunlight skylight - colours

[Maciej]

How to change the sun colour to very yellow (or red, orange..) and sky to very blue, concurrently? Using "blue" HDRI makes the whole scene blue, even the sun-reflecting white stucco areas, which should be yellow. In turn, "yellow" HDRI-sky makes the Scene predominantly yellow, even deep shadow areas...

Using specific evening time doesn't solve the problem, sunlight is not red enough...

Any ideas, gentlemen? 

[Roy Hirshkowitz]

You can't.  It's something I might consider going forward.

oK, so please consider this issue in your wish list.. As far as I remember, there was such a possibility in Ar3, Ar4, wasn't it?

What's your tip to make red sunset view? Is it possible using nXt?

[Roy Hirshkowitz]

Not easily.  A good, well calibrated, sunset hdr would do it.

roy yes you can....set the time to 7:47 morning ...move the slider until you get the yellow sun sky....:)

The sky dome portion does certainly change color.  I don't believe the direct sunlight component does-- I think it stays white.  The overall effect is to tint the light, of course, since the direct sun contribution is proportionally much smaller at sunrise/sunset.

[Maciej]

Roy is right. Furthermore, the shadows are pretty long at 7:47, even in summer... :-)

Roy,

see attached photo - just a picture. One can see red/orange sunset colour, and segnificant blue shadows area... thats wht I'd like to get.

[Roy Hirshkowitz]

Photoshop.  Difficult to achieve with any renderer and probably more user control over automatic sky than I'm willing to offer.

[Maciej]

Roy,

Maybe just a directional light? Not a spotlight, but similar... Just like in Ar3 or Ar4.  Forget the sun. HDRI will do fine, lighting settings set to custom -  turn the sun off, lights (directional) on, sky (hdri) also on - this should work, shouldn't it?

[Roy Hirshkowitz]

Lots of things would work.  No directional lights.

[Maciej]

Ok, fair enough. However, despite these "bugs", nXt is very ok.   :-)
