Oh, hey, don't think I said anything about single frame rendering to get a still
image out of a animation did I? Since I probably didn't and you might not know,
you'll need a Subset_Start_Frame=123 Subset_End_Frame=123 pair of lines in a Ini
file just like you were doing animation but to get a single frame instead.
+SF and +EF is the same on the command-line.
Fact is that with the spray.inc it has to use the clock directly, you can't
define clock as something else and expect it to be seen. Same goes for many
such includes. And the spray needs to get going in order to be fully present in
the scene so you'd want to move ahead into the sequence of frames quite a bit.
example Ini:
Initial_Frame=0
Final_Frame=89
Subset_Start_Frame=29
Subset_End_Frame=29
Initial_Clock=0
Final_Clock=1
Cyclic_Animation=On
Good luck with it, fun and frustration is always the way. Keep asking
questions.

Ok so It doesn't matter for animation or stills the settings would come out to
be about the same then. Gotcha

The reasoning might not make sense becasue of my lack of indepth knowledge of
the laws of POV. What I was thinking was since the bowlish part of the fountain
(the only part I have finisht at the time) looks like the bottom half of a
shpere with an upside down hollow cone in the middle I would need some way to
get the water around the cone but I'm now seeing that that doesn't make much
sense since the water will be tranparent (or translucent I haven't decided)
anyway.
