Some of the shadows are completely black (esp. that of the lemon thru glass
part and the upper part of the liquid). Perhaps you the max_trace_level too
low?
The lemon is nice. A strong bumpmap should be all it needs.

I tried a higher max_trace, went from 25 to 100. There is no visual
improvement. Some arithmic in PSP showed almost no differences and mainly on
the outlines (from the AA calculations?). Only result, everything in the
stats is higher, even priority queue removed.

max_trace 25
Number of photons shot:      445059
Number of photons stored: 1003929
Priority queue insert:         74329914
Priority queue remove:          261665
Time For Parse:    0 h 54 m  36.0 sec
Time For Trace:    4 h 16 m   7.0 sec
Total Time:    5 h 10 m  43.0 sec

max_trace 100
Number of photons shot:      445059
Number of photons stored: 1250207
Priority queue insert:          86199180

I still think there's something wrong here. The lemon thru glass shadow in
particular. It shouldn't be so dark (completely opaque?) unless perhaps the
glass had a ridiculously high ior - and it doesn't. Max_trace of 100 is
certainly an overkill (so is 25 in the glass/lemon case), so the problem lies
somewhere else.
Does it look the same even without photons / in official POV?

As for the stats - lack of patience sure isn't one of your shortcomings :)

Without photons there is no dark part in the shadow of the lemon, neither is
there a shadow of the glass.

It's wrong. It's wrong. It's wrong. It's wrong.
Perhaps you should notify Nathan of this. It may be a problem with the
Photon patch. Perhaps something to do with using transparency in bitmaps...
Not sure. But the shadow with photons should be similar to that w/o photons
in this area. Of that I'm quite sure.
If you like, you can send me the source and I'll do a quick debugging
session...

Try making it shinier. It looks like it dried out under the lights.
Also, the bubbles have too much color... It reminds me of the Oorbs
drink that was out a while back.

It looks to me as though you've got two shadow problems here, I hardly
noticed the lemon problem, at the top of the drink the shadow is almost
solid ( in the shadow on the floor, not in the drink itself ), this
makes it look as though there is a head of froth on the drink, as you
would see on a glass of beer.  I'm sure this hard shadow shouldn't be
there.

Anyway what is a Grenadine made of?

Cheers

Sweetened pomegranate juice if I am not mistaken.

+AD4-It looks to me as though you've got two shadow problems here, I hardly
+AD4-noticed the lemon problem,......

This one is solved (by Margus), I didn't put a photon+AF8-pass+AF8-trough statement
in the lemon. Stupid me.

+AD4-.... at the top of the drink the shadow is almost
+AD4-solid ( in the shadow on the floor, not in the drink itself ), this
+AD4-makes it look as though there is a head of froth on the drink, as you
+AD4-would see on a glass of beer.  I'm sure this hard shadow shouldn't be
+AD4-there.

Tried several things, nothing solved this yet. There should be a shadow
allright but it is mutch to dark.

+AD4-Anyway what is a Grenadine made of?


It's the juice of pommegranate. Verry refreshing.

It is completely smooth, no fine-structure. Try to use
the texture of the pulps for a normal also. This should
do it a little better (I do wood this way: use the "wood"
pattern both as pigment and as normal).
