Exterior Rendering with HRDi sky and Path Tracer.

This is where I am;

this is where am going, how do I get there using HDRi sky with Path Tracer or any other method

[George Ioannidis]

On this rendering sun looks to be coming through the clouds (thus it corresponds to semi-cloudy background image).If you want early morning sun maybe you should try to lower the sun first. It looks more like midday sun position. And I would also try to raise contrast of the image, to make shadows slightly darker and bright areas brighter.

@GI at the reference rendering or my latest post as it is the effect of this am trying to achieve.

[Roy Hirshkowitz]

This one shouldn't require an hdri.  Sun and autosky should do it.  The cars are lousy.  Vegetation isn't bad.

[Ros. Riha]

while we are at it - imho autosky does not change its tone/color according the time of the day/year ... would it be possible to change its behavior to do so?

[Roy Hirshkowitz]

It does change color based on the zenithal angle of the sun (this of course, varies both with time-of-day and day-of-year.)  The color change is most obvious when the sun angles are low.

 

I'm unlikely to change this model much. It's very tricky and currently based on an important paper in the 1990's which unified a CIE theoretical sky with actual measured data in several sites around the world.

[Ros. Riha]

my mistake and apologies, then. I failed to notice the change. Obviously, there is no need to change it, once it is this accurate... only some slider to boost the intensity of the color might be helpful...

What setting would you recommed?

Have to make do with the cars till i renew my rpc license. Plants from AR3 add via legacy wiget. It is the palm tree that worries me.

[Roy Hirshkowitz]

Don't use the cars.  nXt does nice palms-- use the editor.

Exterior preset

Packet tracer

Tone generator; 0.00; 0.03; 1.41

Channels sun(1.08) Sky(0.59)

Sun and Sky intensity (1 and 2) respectively, while cloudiness is at zero.

This is a nice rendering, but too much monkeying around.  You're undoing with the channels what you did with the intensity.  Set both of these to defaults and you'll get almost the exact same picture.  I assume by 1.41 you mean saturation-- this is normally too high but looks good here.

The Path Tracer will give you a similar picture but will add indirect lighting for some additional subtlety.  You'll need to let it go for a while.

Thought I'd have a go at an exterior rendering.

This uses a very high quality HDRI, real world values for the interior lights and no monkeying around with any other settings apart from increasing indirect bounces to 2.
