*argh* I forgot to attach the scene-file..
INI-settings are standard from quickres.ini. It crashes in POVray and
doesn't crash in MegaPOV, no matter which settings I use from quickres.ini .

It's in this section
#version 3.5;
#include "colors.inc"
#declare Photons=off;
global_settings {
assumed_gamma 1.5
max_trace_level 500
}
I think you set max_trace_level too high, try a small value, and work up to
an acceptable level

Thanks! The level was that high because I got a black water surface before
setting it higher.. Now it's at 100 and everything works fine.. except that
there are some white/grey dots in the background..

Hi Dirk
With ior=1.3 : crash
With ior=1.29 : don't crash

I solved it by decreasing the max_trace_level.
ior=1.29 would be wrong.. real ior is 1.33 so my ior already is wrong ;)
Can anyone explain why it doesn't crash just because of 0.01 difference?

well, I looked at POV help, and my best guess is it relates to the angle of
refraction. with a diferent angle, you would strick different areas inside
your bowl, and each time you hit it creates new rays. Well with a decreased
angle, I expect it doesn't get to an unstable number of trace levels. But
since you want a realistic refraction of the water stay with the ior=1.33
and tweek the trace level.
I'm sure others may have a better way of explaining this if I confused you.
