Night render test
-
hi all,
i'm fooling around with night renders with SU+VRay. the test scene is simple - a VRay plane, a box with windows, a light inside the box and some environment. this is what i've come up with; putting the obvious need for post-production aside, what do you think?
the light is VRay's Rectangular light, i kept the physical camera on and adjusted exposure accordingly (shutter speed 10, F-stop 4, ISO 100), reduced the GI and BG color multipliers to 0,1, kept the GI color on TexSky and switched the BGcolor for a HDRi.

I think your rendered scene is too warm in contrast with your rather cold background. The light should be warm of course but your shadowed area needs to be a lot bluer. If I remember correctly there is somewhere in the Environment tab that can help change that. If not it will have to be done in Photoshop afterwards.

My suggestion for night renders is to use a low res HDRI that is blurred in your GI slot and a hi res HDRI for your background for reflections. SIBL has a nice free collection http://www.hdrlabs.com/sibl/archive.html Once you have your environment, then you can work on lighting the interior of your cube.

thanks, HDRi probably is the way to go with night scenes... i still have to find my workflow though, so thanks for the tip
