Creating Atmosphere (fog) in a cityscape

[buzby]

Any thoughts on creating an atmosphere across a large cityscape? My scene has the same look across from end to end. I disabled autofocus and have DOF but does not really do much. I have seen the fog created in some scenes and am wondering if this will work for cities or if there is another option that some have used that will work better.

in this camera position i prefer to use some big neutral planes with very low opacity at different distance, it works very well and it's extremly fast to render

Another option (other than a fog volume) is to use the deep channel kernels "Z depth" render output.
Use this in post to add some fog based on depth. Play with the Z_depth_max slider to to get some useful output from the Z depth render.

Thanks
Chris.

I was reading the following suggestion for creating fog in the 3ds max review. Anyone know how to implement this in the C4d plugin, I would like to try in in comparison to the suggestions above.

"Another nice trick is using an SSS shader to create fog and volumetric light effects, simply by applying the materials to a sphere with inverted normals enclosing the camera."

Here is a couple of example with and without the surrounding camera sphere:

is the same tecnique, but it's much slower and difficult, remember to set the coustic blur at 1 in pmc and pt
