    Autodesk Raytracer - Hazy Look when Sun and Artificial is used

    I'm having issues with a scene and hope someone has experienced this and has a fix. No matter what time of day I chose that lets light thru the windows I get this haze like the light is catching particles of dust in the room. Needless to say I don't want this look. I've tried diff. settings. With artificial only, all is well. but as soon as I want the shadows on the floor all gets hazy.Click image for larger version.

    It looks like you're seeing the horizon and sky. Dumb question but are you, by chance, looking into the room from outside through a reflective material (like glass)?

    Sorry I'm still not happy with the images, but here are progress shots for your review/comment.

    I think these look good (it's what I would expect out of Revit). I'm guessing you're still not happy with the lack of contrast in the scene? I know there are precious few rendering controls in 2017, but I think you can tweak the exposure controls to get what you are after. Color temp a bit higher to bring out the earthy brick tones, shadows darker (I'm looking behind the brick columns), maybe knock down the overall exposure and tweak highlights up. You may need to make the dark ceiling material a bit lighter tone (or less saturated?). It almost looks like you have some oblique reflections on your brick material, which may be why the columns render "less hazy" than the elevator core.

    Or fix it in post, I suppose.

    I like the color in the first image (no people) a little more than the second image. It is a bit warmer.

    The other thing that jumps out at me is that the entourage is floating a tiny amount and isn't casting shadows.

    I agree, the brick is taking on too much oblique. While it certainly wouldn't be a true matte finish, it wouldn't pick up the coloration like that and the brick looks like paper with no depth. Try slightly adjusting the bump map there.
    The light coming thru the windows on the exterior is far too washed out. In fact, its completely washed out, which is how the computer see's it, not how a person would see it. Try adjusting Midtones and Highlights. I typically take the Shadows down from 0.2 to 0.12 as well. Saturation roughly around 1.08. White Point above the default setting of 6500 but less than 6800.

    This is an opinion observation:
    Lifting the couches slightly and putting legs on them would really help elevate its appearance since it would render a shadow line under it.
