Kerkythea Rendering System

trying to figure out this program this is my first time using it.. how do you turn the reflections down? I am just trying to show a corrugated metal patern with a little shine.. and I cant figure it out.. and anything else you see that could be of us, comments and critiques are welcome.
Thanks!

if you are using reflection then make the colour darker, of if you are using specularity, iether make the colour darker or decrease the "specular attenuation"
Otherwise starting on a scene as complex as that is very difficult (yes thats what I did)
If you just want to learn how to use it a render of one of the cars in there would be more than complex enough...

download all the materials you can, and use those.
insert a spherical sky or "global".
