  out of memory (Message 1 to 9 of 9)

Hi all,
I have a scene with a fairly large number of objects (a.o. Poser figures). 
When parsing the scene, I get the following message, referring to one of the 
image_maps for a Poser figure:

Possible Parse Error: Insufficient memory to allocate intermediate image 
storage.
Fatal error in parser: Out of memory.

I imagine that this means no more image _maps can be held temporarily in 
memory, but can I do something about it (except decrease the number of 
objects and/or image_maps)?

Thanks!!

Thomas

You could reduce the resolution of the image_maps or install more memory.

Hmm, yes.
I found another way by starting up again POV-Ray (3.7 by the way). This time 
parsing and rendering works. There is a bit of swaping occurring though, but 
that can be expected.
I assume that previously, I had some memory leaking away while rendering 
several small test scenes. The result was a shortage of memory when I wanted 
to render a big scene.

You could increase the size of your swap in order to have more memory
available. If you don't have a 64bit processor, the upper border for
this solution is 2GB or 4GB memory.
I don't know whether using swapping will slow down rendering, since I'm
not sure what povray means with 'intermediate' in the error message.

Yes that is a solution which I have considered too. But then, the second 
time, after restarting pov (and obviously clearing memory) the render went 
quite fast without really much swapping. Swap memory stayed just below 2 GB.

I am not going to tell you things you already know, but to complete the
collection of possible solutions: you can redirect a bunch of figures to a

visible in a scene with dozens of persons. I am doing this all the time.

This is a known issue with the beta, and is not always due to insufficient
physical memory (it can happen, for example, when there is insufficient
contiguous virtual address space available). We are working on a solution.

Oh, thank you, Chris.
I was wondering indeed if this was similar to that other instance of out of 
memory. It seemed different though, which explains my message.

Yes, thank you for reminding me. I had been thinking along those lines too. 
You give me a good reason to implement that :-)
