Thanks a lot, Klaus!
Well, you're right, it's quite an ignorant audience. Or the band sucks.
I used what I had. To avoid too much identical instances (unfortunately some are noticeable) I had 18 populations of different people and a few single higher resolution ones near the camera.
Actually I loaded the stage into 3ds max and placed spotlights wherever I needed them. Then I exported the lights as FBX scene and imported it into my scene. So far it was easy. Too bad the lights weren't spotlights in TG, just lightsources (omni lights), so I had to replace some of them and rotated them correctly (only the actual spots). Quite some fiddly work...
It took about 9 hrs to render in 3K.
I took the challenge to render such a scene in TG. Yes, it can be done. The biggest problem is the handling of things. Once you have rotated a spot for example, the rotation handles sometimes become quite unpredictable as I already mentioned in this thread:

I think, this is really the problem with Terragen. There are some features, that would be essential, and they aren't implemented yet, which makes it very hard for new users to get around these problems. You need a lot of experience to find (or remember) solutions, and a lot of times they don't sound logical, but they work.
