Autumn Atmo

[Helldoor]

Hi mates,

it's me again, being not so experienced and asking dumb questions. So...

I'm currently working on a visualisation for an architectural contest. Fitting the current season, we'd lake to make it have some nice and smooth autumn atmosphere.
I use DomeLight with a HDRI map + Directional Light (light orange) for the Scene Illumination. You can see all the settings in the attached pics.

First Question : Do you have any suggestions how to optimize the Illumination for an autumn Exterior
(is true, a lot of atmosphere comes from the post production in PS, but I'm currently trying to improve the quality and atmosphere of my renderings).

Second Question - I'd be vary glad, if you dive me some advice on how to improve my materials. I don't find my Bricks very realistic and the Glass doesn't fully convice me either.


I'll keep in touch and post the results of your suggestions. Thanks in advance, I'm glad that I can learn from your experience and tipps.

My taste for Bricks:

1) I don't like to use gray color in Fresnel map. Better to use the reflection multiplier of 0.7.
2) I don't like to change multiplier for Reflcetion map better to use Filter.
In material like this you can use the image of the brick to get a more natural reflection.
3) I don't like to have glossy map.

Thx, skysurfer. I'll try that.

----------------------------------------------------------------------------------------------------------------------------------------
Edit: I've changed the Brick Settings to:

. no Glossiness Maps
. Reflection : Falloff (Fresnel) - Color 1: black ; Color 2: white ; IOR: 3
. Filter : I didn't have an extra speculiar map and used the bump map as filter bitmap

I like the result. Check pic.

One further question: in what situations do you use the bump as one of the colors in the falloff map?

Thanks again!

Looks better. I would prefer to stay at 1.55 as ior in the fresnel and play with filter multiplier to have specularity. (more than 1).
i never use map in falloff, but could be useful to mix the falloff.
