View Full Version : Rendering
02-07-2003, 06:45 PM
I'm rendering a scene on a Mac dual 1 GHz G4 with 1.5 gigs of ram on OSX and Lightwave is only using 50% of the CPU and 5% of the ram. Lightwave is also set to use 2 threads.
Now, just for fun, I set up a 400 MHz G3 on OS 9 and it's rendering just a tiny bit slower than the Dual G4.
Any ideas why?

I run lightwave 7.5 on the exact same system with the same cpu/ram and everything and have been wondering about the speed for a long time. I know that dual chips are not supported for the mac.....yet. Hopefully when lightwave 8 comes out there will be support for dual processors. As for the 5% use of the ram i have no idea why it would use so little ram.
Keep Wavin :wavey:

Hey how do you guys see the system resourses like that? I use 2 Mac here both Duel Processors and that would be nice to se what system resources are being used.. hehe.. Oh and My Lightwave 7.5 works with my 2 processors just fine. You guys know about LWSN? Or screamernet?
Here at work we use LWSN and actually i can render on my second processor and rarely if ever feel a hit on my computers performence when im modeling or animateing.. only thing i think hit my system is a lower amount of ram available. I can render out twice as many frames as our single processor G3 computers. And faster by far.
If i can find that documentation on LWSN i had that showed me how to do it ill post it. hehe till then im back to work 8)~

just out of curiosity...what happens when you set your threads to 8? also, how much RAM are you allocating to your camera?

We set our memory in LW to be just enough to render in 1 pass instead of 2 or more. I usually just bump it up to 60 or more, but i think u could get away with putting it a lot less and still get it to go in 1 pass.. As for threads i never really look at what its at.. i think 1 is safest and i can still render on both processors with it set to 1 8), i don't think LWSN checks for that number when it does its render. I would doubt screamernet would either but unsure on that.
I don't think you were askin me that question but just thought i would give ya my settings as well hehe 8)

Thanks guys. Does anyone know of some documentation for LWSN?
To find out the system recourses on a running application:
1. open the terminal application (/Applications/Utilities/terminal)
2. type in the following without quotes "top"
3. and there you have it. real time feedback of the resources used by each app.
Thanks again everyone for posting.
