Does it have any effect on the fish movement if the blue box around the fishes is big or small?
I'm not sure...
Hmm, I'm not sure as well. might have to experiment on it
Current status: working 2-10 really s*#k ^_^
Yes, the blue box defines the area in which the fishes are able to move.
If you make the box to small, this is very noticeable.
For example when I created a shark or a dolphin I had the feeling it would move much further than the box.
Noticed that too. I think the box we see is a boundary for the fish their path.
Like they're attached to the box with a spring. Yet that's pure speculation from my side.
