I am not sure if POVRAY crashes on my scene file or not, who can help?
It starts to parse the photons, but at position 45176 it suddenly stops
doing anything. Maybe POVRAY still calculates, but I am not sure. At least,
it reacts properly on abort request. Who would like to test my file (see
attached ZIP) and tell me if it crashed or not?
Thanks.

I know nothing of these "photons" of which you speak, but the unmodified
contents of your zip file can be used to generate an image. It takes a
while, but it doesn't crash (3.6.1c.icl8.win32). Stats in p.b.s-f,
image in p.b.i.

No crash. Maybe there are large areas that are covered by the photons shooting
that can't receive any. Here it pause at 45182 and 45193 with autostop 0.
It still use 80 to 97% CPU.
You may have some object that have extremely large and almost empty bounding box.
Try removing all objects exept the ground plane, then add the various objects
one by one until you find the problematic one.
Effeciency tip:
You have some maps like:
pigment_map
{
[ 0.00 Gray95 ]
[ 0.20 Gray95 ]
[ 0.20 Gray95 ]
[ 0.75 Gray30 ]
[ 0.75 Gray30 ]
[ 1.00 Gray30 ]
}
that can be cut down to:
pigment_map
{
[ 0.20 Gray95 ]
[ 0.75 Gray30 ]
}
for exactly the same result. In the present case, a constant shade of Gray95
from zero to 0.2, a ramp from 0.2 to 0.75, and a constant shade of Gray30 for
the rest. The short version is easier to write, debug and maintain.

Thanks for the participation. Hmm, was anyone doing the file with a
resolution of 3200 x 2400 pixels? I would need the saved photon file (.ptn),
that would be a great help for me. If I could get that file, my computer
could probably render the scene in a good time. Thanks to everyone, who can
make this possible!
Spock, can you post here the picture you got? I would love to see it.

I could, but I think it violates the charter for this group. Check out
povray.binaries.images instead.

By the way, the entire modelling was done out of my head, no visual editor

Thanks, I just saw it! Can you create for me the photon file (.ptn) for a
resolution of 3200 x 2400 (AA0.3)? Just look to the begin of the scene file,
there is an option to save the file. Please, if cou can do this for me, send
it to me. Great thanks! On my system, it takes tooooo long (I gave up after
half a day).

Sorry, I don't have that kind of horsepower. I think you need the
services of a render farm.

As the photons are independent from the resolution, you can render at, say 320 x
240, save the photons to a file. Then, for the high resolution render, you just
import the photons map from that file.

Hm-hmmm, I see. Thanks for the advise. I even tried something similar
(slightly different resolution). But still, after half a day I gave up. It
is this condemned (critical) 45176 position, where everything appears to be
come to an end.
Hopefully someone can supply me with that file...

I'd like to provide you with a photons map, but it only stop 2 to 3 100's later
on my machine. It even stop if I only leave 1 chopper.

say again?!
It just took me 9 minutes in 512x384, no AA, no Radiosity, no Photons! and just
a single chopper!
like some guy above said, you need a render farm! Does the chopper really need
to be a mirror?

Hi Nemesis,
in fact, to talk about the "mirror" effect of the chopper: I developed the
scene file some long time ago. It looks very different with the previous
version of POVRAY (v.3.5), as far as I remember. With version 3.6, the
entire image looks much softer, like an increased radiosity value for
everything. But in addition, the textures just don't look anymore the way
they did. The chopper was supposed to be glossy, yes, but still to show
clearly a color move from light gray (at the bottom) to dark gray (at the
top of the chopper). Now, with version 3.6, the gloss became to a mirror.
I do not want to change too much in the scene file, I prefer to wait how the
final version of POVRAY 3.7 will interpret certain attributes.
Render Farm: can anyone post a link to get more information on that subject?
I might be interested in such a "Render Farm".

it is a mirror because "Glossy" from finish.inc, which is an old file, uses
reflection. and not even fresnel reflection, but simply reflection and much
specularity. I don't know exactly what is there about glossy in it...

The zip appears to be corrupt. Appears to contain a single png file,
