#High Res Render lockup
7 messages in this thread
What am I overlooking? I am rendering an image at 4,572 x 3600 on a
P5-100, 32MB Ram, #9GXe Video card with R4c1 and Vibrant Liquid Speed
drivers. The image renders at 640×480 normally. I set the display
to NULL and the NO DISPLAY button was turned on in the rendering
option box. When I go to render, it locks up in computer during
the first step of the rendering process. I have done other images at
1296×1000 without problems using this configuration. Have I left
something out, or is it a memory shortage problem?
Thgansk for any insight,

Rich,
when rendering a high resolution image (4,572 x 3600) with only 32mb
ram you are going to build a large swap file. Make sure you have a
huge amount of disk space on the swap drive. Don't rescale
backgrounds during the rendering and make sure save last image is
off.
Swapping with large renderings and big swap files can push a disk
sub-system to breaking point, so beware.
Thanks Martin, I will follow your suggestions and keep my fingers crossed.

Rich, Martin is right. I do quite a lot of rendering in the range you
are working. Before each render I optimize my disk and make sure I
have at least 700 meg of space in the drive partition set for
swapping. This, after having a few crashes myself. I now seem to be
having the gods on my side because I haven't suffered a crash for
some time. PS I have 64 meg of RAM in an EISA 50 and depending on
how complex the image is it can take sometimes 18 to 24 hours to
render.
Will,
Thanks for your input. I followed Martin's advise, and was able to render all
but the very highest resolutions I was asked to produce. The disk optimization
sounds like a good trick. To eak out the images on my machine I went to the
Optimize IPAS for optimization, and also made everyting into one object. This
let me get 2940×2160, or 9.8"x7.2" @ 300 DPI for that particular geometry.
Thanks again,
Rich Schwartz
Rich,
The high resolution stuff is a bear on space. I'm beginning to think about a
huge solid state hard drive to optimize speed as well as ability to handle the
sheer size.

Will,
I've seen those units. They are appear to be very rugged and dependable, but
if I remeber correctly they are quite expensive. Good luck with your choice.
