Hi!
Rendering a scene with an image_map wrapped around a sphere (2048x1024
pixels) I always get a crash on my Athlon 2 GHz+/XP system after about
100-150 frames. The scene renders single bmp frames.
The problem begins with extreme duration of the parsing process. The scene
is normally parsed in 1-2 seconds, later the process takes about a minute
or so. Later povray stops saying 'can't allocate xx bytes to abc.jpg (the
image_map file).
Yesterday I lifted my memory from 256 to 768 MB but the crash remains..:-(
Is there a known bug in 3.5?
In my opinion memory situation should be the same after one and after 10k
frames or does POV cumulate any data in memory while rendering an
animation? Or is this a WnXP issue?

I've recently rewritten BMP handling, would you like to deliver minimal scene,
settings and image_maps to me for test (preffered via downloadable zip)?
Thanks in advance.

A problem of that sort was uncovered recently (see thread "crash after 63
frames" in p.unofficial.patches at the beginning of November), though it
seems to be related to image_pattern and pigment_pattern using an image_map
but not to using image_map directly. This particular issue will be fixed in
the next release.
However, I sometimes have a memory problem with repeat renders of files
containing direct image_map statements (particularly with large maps), but I
have not been able to replicate it so far.

I've had this too. Using meshes and image maps. My work around is to use the
"Queue". Create several ini files with sequential Subset_Start_Frame (+SF) and
Subset_End_Frame (+EF). E.g.
1.ini -> +SF1 +EF10
2.ini -> +SF11 +EF20
3.ini -> +SF21 +EF30
USW
Use the task manager to tune the distribution, PF Usage is a nice stepped
sawtooth.

Stephen

Yes, the scene uses a image_pattern with image_map...:-(

The scene uses JPG files, should I anyway send you a zip file (via mail
possible?)?

Yes, please.

I have minor problems with attachements in my mailbox recently. I do not know
when it will be fixed so I would prefer something downlodable. I suppose using
binary group on this server would be good choose.

Thanks. I tried your scene and indeed it agresively gathered memory under 3.5
(I was able to render 70 frames). Good news. It was related to one of already
fixed bugs. I tried recent development version and rendered 1000 frames
without any wasting of memory.

Great! Thanks a lot!
Can I get the fixed version anywhere?
