Thank you.

Yes, there are no raytraced shadows. The DMap-Res. is 4096 and the DMap-Filter-size was set to 4...
The Render Globals were something like this:
AntiAlising: Highest Preset adjusted with: 12*shadows
Raytracing: 12, 12, 4


I thought about animating it, but when I remember the time for rendering, 26 for the first and 32 minutes for the last picture I get pessimistic. But perhaps an animation without raytracing would be possible. There these images needed 4 and 5 minutes or so..
