Rendering in LightWave

[qutaibah]

Hi all,

I have a 1GHZ Dual Processor G4. is there a setting in lightwave or somewhere else that I should enable to get LW to use both proccessors?

thanks

Turn multithread in render options panel on (2,4,8) !

Hi LMountain,

thanks for your reply. Can you tell me a bit more bout multithread and how it works?

thanks

99% of the time when using a Dual CPU G4 you get the best result if you set multithreading to "4" and add more segment memory so the image renders in "one" segment..

good luck with your G4 :)

how do you add more "segment memory" if I may ask.

[Meshbuilder]

In camera settings, segment memory..

[qutaibah]

so what dose adding more segments memory do to a rendering.
is that the seme as assigning how much memory LW can use up?

thanks

Im interested too I have 1.75 ram and a DP 1.25.
I thinl segment memory is important on how high rez u render at?

From waht I remember (haven't read the manual in a while), segment memory is utilized to determine whether a frame renders in 1, 4, 8 or more segments (little square cubes) of the image. If you can render in one segment, your render will be quicker, because the calculations for the whole image happen at once, rather than 4 or more times in a row. To maximize the utlization of segment memory, set it just high enough to render a scene in one segment. Typically this is around 16 or 32 MBs (16000 or 32000 on the panel). This memory is allocated separate from a complete render, so don't treat it like the OS 9 memory panel. Put in just enough to make segments 1 (if you can).

"SML lets you tell layout the maximum amount of memory to use for rendering. This means you can set this value to the same amount of RAM in your system, and LW will only use what it needs." (inside LW 7)

Well, i didn't do that, but I did give it 100MB just because. If I render a very simple scene, 1 SEGMENT is actually much faster. If the scene is more complex, a setting of 4 works best for me.
