I am using maya's physical sun and sky to render a large outdoor city model and I am having difficulties adjusting two things...

First, the shadow color and transparency. I cannot figure out how to adjust that, closest i've come is someone suggested using the "shadow_transparency" node, but I have no idea what to connect that to on the mia_physicalsky, sun or exposure nodes.

The second is trying to get better contrast and colors in the render. The PS&S lighting cranks up the gamma so high it washes all of the colors out. I have knocked the shading mutliplier down to .5 or so and I get pretty close to what I want (less blown out at least) but the textures are still washed out. I'm really hoping I dont need to go back and add the gamma node to every texture.


Any suggestions would be greatly appreciated, thanks in advance!
