WOW, I'm seriously impressed!! Easy to use, impressive results!!
Attached my first test result:
The aquaria have an infill of a transparent green box. Behind the left one a 25% light, at right 50% light. On top of the left aquarium is the fish bowl (the fish seems a little big?). In the middle a transparent sphere and cylinder with 5 20% lights in them.
The result looks very natural.
thoofman: I'll see what I can do to approximate better the result you wanted.
