Does not work either... only the same black void!

That's true, but I want to do animated flights at 5 to 10 kms over 
ground, with only those data tiles to be included which actually would 
be in the FOV of the camera... and landscapes would not be realistic if 
one could see let's say Mt. Everest from central Europe...

See you in Khyberspace!
