Forgot to mention soft shadows were also on. Found out with true ambience to get soft shadows you have to have it set for the light (or sun, whichever you are using) and in the premium settings for it to work. Right now I'm conducting experiments to find out how exactly light is working with true ambience. I thought I had it figured until the latest render I'm doing now which I can't explain. Will post when finished but probably won't have time until sometime Saturday. I do know one thing, light isn't reflecting at all. Wherever a light hits (say from a spotlight) that is where the light beam stops. True ambience seems to work on hotspots in some way. You'll see when I'm finished.
