Good techniques for exterior renders and light?

Could you post an example.

Random example:

Tweak color balance adjustment layer in PShop:
in highlights- exaggerate yellow
in shadows- blues
P.S. try to google 'osmosis vray tutorial' (check them both- interior & exterior)

I do a lot in Photoshop, simply because it's faster.

Render out a material ID pass and use it to make selection for all the glass.
Select everything thats inside the windows and tweak lightness and color to your liking.
i always use layer copies so I don't edit the original render.
Open up an image that can be used as reflection and mask that layer with the "window selection".
Blend and try different blend modes until it looks right.
I also use images of office windows at night that I tile and stretch to size and mask with the same window mask just to get some detail interior without having to build it in 3d.

I would go with Pixero's way. I would just add warming filter in the workflow. BTW that sample image is so unatural. Why would somebody need lights in the glass building with all that brightness going outside....

Just to boast that they can do a render like that.

Thom why dont you post more of you work?

thomthom · 16 Mar 2011, 10:14

So much to do - not enough time.

Plus, I'm often not happy with the results due to time constraints on the projects.

In that example, thomthom, there are definitely lights inside, right? What about giving them a color? Tungsten 100W have a color temperature around 3200K which is about RGB 255,241,224. Because of the reflection on the roof overhang, it looks to me like they are actually changing the color of the lights.

I'm all for some post-pro, but the more I can do in the rendering itself the better, IMO. That way I can reproduce the effect as I change the design.
