#Speeding up rendering?
7 messages in this thread
Everyone…
awhile back I got a list of things that can all have an effect on rendering
clarity and quality. I'm hoping for the same thing when it comes to speeding up
renderings.
As an example: A scene I'm rendering has only 4486 faces <4486> 3 objects, all
metal reflection materials, Highlight on one object very slight. No background
and 3 omni lights.
On a DX2/66, 32 meg ram excess HD space. rendering out to the par. it's taking
almost 14 mins a frame at the point where the objects take up most of the
screen.
What can I do/turn on and off/not do that will speed up rendering times without
affecting the quality of the final images??
All you guys I admire……I await your suggestions!!

Patrick,

your scene is pretty minimalistic. The only things I can think of are to check
that your geometry is optimal. In other words, is the geometry more complicated
than it needs to be. You might not need as many faces as you have. Try a few
stills using lower face-count spheres on the frame where the spheres appear
largest. Go with the lowest face-count geometry you can before you start to see
undesirable edge profile effects.
4000 faces is not very many to result in 14 minutes/ frame. You didn't mention
whether you have any IPAS's running that could take time like Glow. The only
other thing I can think of that would make a rendering drag out is the Ray
tracer for shadows but You didn't mention this. Are you using Automatic
Reflection? What part of the rendering process (red bar) is taking most of the
time.
I tend to favor some hardware diagnostics on your computer at this point. Do
you have any bench mark software for your CPU? such as Norton desktop or
Norton Utilities? Be sure you have your internal and external cache turned
on on your CPU in the CMOS setup. What speed RAM do you use. It should be 70
ns.
FWIW I have a DX2-66 with 32 megs and a quick test rendering of a similar
project with 6000 faces and 5 objects and three omni lights is taking 38
seconds per frame.
Patrick, are you using standard reflection maps, or automatic reflection maps?

In addition to what the others said…make sure u are not asking 3DS to check
many unnecessary paths for maps. Esp. if the are on CD Rom. I know…this will
not add minutes to a render but 20 to 30 secs per frame over many frames does
add up! Just my two cents.

Also make sure power.exe is not being loaded in your config.sys/autoexec.bat
(not sure which one it gets stuck into). LAM

You haven't given *nearly* enough information for anyone to likely help you.
But, based on your extremely minimal description of the scene, I'm betting that
you are using Auto Reflections to the extreme. If so, try reflection maps
instead.
