However, I have troubles in inverting the direction of the beams. I have created a spherical source:

/gps/pos/type Surface /gps/pos/shape Sphere

but want to invert the beam from outwards (default) to inwards. If I simply change the beam direction to:

/gps/direction 0 0 1, the beams disappear.

Any suggestions?

Thanks in advance, Constantin.
