Hi everyone,
and forgive a probably already mentioned topic (though I couldn't find it via serach form)... I am working on my first outdoor scene and teaking ambient light..
I don't understand why, whenever I switch to the internal daylight system I get such bluish results on my model.. I try to move the latitude/longitude sliders and I play around a bit, but the only "blue tint removal" I can get is by switching to very early or late hours of the day, producing in most cases unwanted shadows and mood..
The other "half solution" I could find, was changing the camera response.. The Agfa Color Vista II 100 CD seamed to help a bit, but I was wondering if I am looking in the right direction or just missing some other important elements.
Or maybe, the question could be, is the daylight system the best (though there is never a "best") way to light up exterior scenes, or HDRI images and light emitters to a better job? Do my models have to live in a blue world?
Thanks for answering
Bye

I did find a way, just wondering if is a good one (well, I suppose that when a result looks good, is good)
I have placed a large plane to act as emitter over my exterior scene, in a position close to the sun's direction. I gave this plane the maximun emission power and I tinted it (with light's temperature) kinda warmish color. Then I mapped a float texture to the opacity slot, to make it completely transparent (didn't want to project shadows at all).. and, that's it..
In other words, my solution was to light the scene with the normal daylight system plus a strong warm emitter to remove the bluish tint.. (and a correct comare response)
Fixed, all nice now, but, since I believe that there a still many many feautures in Octane that I simply don't know, I am still wondering if the default bluish tint is my "fault"..

Your way of fixing this is the exact same way i used several months ago to overcome the problem. I even did a setup with planes distributed evenly on half a sphere, each with it's own material and lit them individually in octane as needed.
However, the back draw of this is a huge slowness in render time because of using emitters, and more fireflies because of the strong power needed to simulate the sun.
So, no it's not only you, daylight system needs some improvement and more parameters for the user to control it's color/mood without being forced to use image curves that affects everything not only light.

Thanks Marco it is happy to see that i am not the only one...

I agree .. Daylight is too bluish... I always need to add some filters in photoshop or after effects to balance the light..
Please do not say to me it is physically correct - please you know it is really blue

I wish we had more options in daylight system ... as HMK mentioned..

In fact, I really think that the daylight system is physically correct, but what happens here is that in the real worls, our eyes, or our brain cancels the blue color ! The same thing occurs when you wear sun glasses with tinted glass for example : after a moment, you forget the color of the glasses and see the colors of the landscape. This natural correction seems to not occur when you are watching a photo or a screen.

Nothing that Photoshop or Gimp cannot solve in a matter of seconds. That`s the efficient way -> White Ballance.

yes , i am agree

i think a good stuff is white balance like adobe lightroom for adjust kelvin temp

Best regard

The Daylightsystem has a very unrealistic light at sunset: To much yellow/ dark, unsaturated colors and not enough bluish/violett and orange colors.

I'm happy if the refractive team works on this

Kind regards

Could it be a matter of scale?

Have a look at this thread: http://www.refractivesoftware.com/forum ... f=6&t=5716

Good luck.
