What am I doing wrong here? I see NONE of both types of shadow.
Thought I'd at least see 'something'...? But nothing, zip, nada, whatsoever.
The pic on the left, that I just want to be a (quite dark) black shadow.
The other one - preferably flecky, if not possible, less dark shadow.
BTW: Any way I can regulate that for longer and shorter tunnels (darker/less dark?)
Need I remind you that I am very dumb and very blonde, but not a girl so it is no advantage...
