scanline renderer

[sstamfb]

Hi all,

i'm doing an animation using default scanline renderer. My computer has quad core cpu. During the render procession my computer uses only the 25% of cpu (just the one core?). Is this normal?

 

Thanks

Did a quick test and yep, scanline uses more than one core. You just can't tell off-hand since there aren't multiple buckets going. Just a line.

go to customize>preferences>rendering and make sure "multithreading" is checked.

multithreading is on. when i do mental ray rendering my computer uses 4 buckets, but in default scanline or when i prepare a scene it uses only the 25% of cpu ....i thing something is going wrong ....

Is it a large enough rendering that all 4 cores would kick in? Have you tried a different scene??

 

When I render on my Quad core, all 4 charts jump to +/-100%.. but if it is a very small scene only 1 core jumps to 100% (I am talking about scenes that render in just a couple of seconds).

i have a large scene... my windows are xp64 and i use cpu extreme quad qx9650.

Only in mental ray things seems to be normal...

What about on other scenes? Just start a brand new one, throw in some random objects with random textures and do a few tests - see if all 4 cores kick in... they should.

Hi SEH,

i load another scene but the results are the same.... i use max 9 32bit and xp64.. might be a problem of the max 32bit

 

thanks

You run XP 64, but MAX 32??? :huh:

 

That defeats the whole purpose of running a 64-bit OS.

 

I would say that has to be one of the reasons.

i run a 32 version of max on a 64 machine. it does not defeat the prppose because max can access more ram. the ram limit is a windows32 problem, not a AutoDesk problem.

RAM limit is a 32-bit problem. Period. A 32-bit OS/System/App can not access more than 4GBs of RAM. How much RAM do you actually have??

a 32 bit app can only access 4gb of ram under win64, but isn't that twice the amount it could access under win32? so, i stand corrected in saying that a 32bit app can utilize all the ram available in the machine, but it appears to me that you can still gain a performance boost because max32 can access the full 4gb?

 

i have 8gb. i wasn't pushing IT to install the 64bit max because I didn't think it made a difference. however, i will still wait until we roll out 2008, because i don't want to bother reconfiguring my setup twice. ...who has that much free time.
