Atmospheric Haze
Hi,
I've been using Twilight for the best part of a year for film production design, especially environments.
I've used the "work around" of comping the Depth map back over a scene in Photoshop... but, honestly, who doesn't want to eventually see those great "God-Rays" of light beaming through a hazy atmosphere of your cathedral interior, or from behing the rolling hill valley scene you've just created. Or just subtle halos around the lights on your night scenes (without having to airbrush them in later).
has anyone attempted this yet and got even a glimmer of how it might be done?
Would be truly the perfect "in-Sketchup" rendering engine with this sort of thing eventually incorporated.
Cheers,
Woz.

You mean like this?
Volumetric Lighting - Special Material (Light Beams)
However, you may find something useful here.
Licensed users of Twilight have access to a very fast "God Ray" material library and complete tutorial to get this effect easily.

Re: Atmospheric Haze
You're upgraded now. The link should work.

if this volumetric lighting will work only on biased preset easy method 1-7(correct me if I'm wrong) then how about other materials or models in the scene that needs unbiased method (using easy 8 or 9 method)?
Suppose, I have a scene that needs unbiased render and need to produce the caustic effect that will come out from a stained glass window and at the same time, I want to achieve a volumetric light beam effect coming from other opening in the scene. Will this be possible? or do I have to do it in post pro.?
I don't have the scene yet, I just figured it out what if I need biased and unbiased together in a scene.
Re: Atmospheric Haze
Caustics from stained glass windows render with any setting from Low or Low+ and higher. Search the term "stained glass" here on the forum.
All settings in Easy 1-7 can be adjusted to render almost anything you want to throw at them. See the Tips and Tricks Section.

Re: Atmospheric Haze
Interesting note: One odd "quirk" with this method we have noticed is that the volumetric effect will not show up if you have a scene with a light emitting surface driven by a .jpg or .png image. If the light emitting surface is driven by color, these volumetrics render just fine.
