allocate more ram to 3Dmax
show user profile  is
Hi out there,

i hope you can help me, cause i am loosing it here. I just upgraded my computer to 24GB of RAM and it seems it has changed nothing to max's render time issues. How can I solve this? I thing I allocated the RAM properly. And ran a test on max.
Anyone any idea of how to do another test? Or tell max to use all the 24GB to go faster? I am using a Windows 7 Pro.

Thanks you so much for any advise.

max uses as much as it needs. if its not using more, it doesn't need more. and RAM doesn't usually increase render time anyway. Here's a general rule of thumb

Faster CPU/More cores = faster renders
Better graphics card: faster viewport speed.
More RAM = max can handle bigger, more complex scenes

Ram is not a processing unit, it stores information.
If you never hit a ceiling before upgrade, it won't make max go faster, only capable of rendering bigger and more complex scenes.

In short
Whatever it uses, it doesn't need more at the time

EDIT: damn :P

But there must be some way to go faster?
My CPU and card are fine I think...

There is no such thing as a "Fine" CPU for Max.
if you were playing a game, then a CPU might be fine enough to run it smoothly (in conjunction with a proper GFX card). MAX however will keep pushing the CPU no matter what type it is.
so like Grotey said. Faster CPU = faster Render.

The content of the scene you are creating determines how much RAM is used.
The CL and MHZ of your RAM may have a small impact on render speeds, but CPU is by far the most important thing.

also simpler/better/more tweaked lighting and effects and such will optimize render time

Terribly boring signature.

Ok. Thanks you guys.
I am rendering an image of a store with 91 lights, a daylight and 6124 object (412598 faces) it says in my report.
When I rendered it on 320x240 it took 20minutes with FG. So I can already see that max is using the new available RAM.
I also tried 320x240 with an AO map but this took like forever and I stopped.
When I rendered a HD picture the last time (before the upgrade) it took 8 hours, is this normal?
The goal is to get a HDTV 1080 picture here (and some 20 more or so) + an animation by okt 15th. So I was doing some tests.
But if the final render take up to 8 hours each I am pretty f****.
So I hope the new RAM improves the situation.
BTW: my CPU is Intel (IR) Core (TMi7 CPU 950@3,07Ghz 3.10Ghz and my card: GTX 580 3GB.
My computer comes from a guy that assembles special gaming computers. So this is pretty good or isn't it?

Thanks again.

The efficiency of your scene, AND the rendering parameter setup is HUGE in overall rendering time.

How efficient is your scene? Is everything optimized perfectly? 91 lights? wtf is your scene?
Many people setup incredibly overly complicated scenes that kill render times,.....knowing material settings, etc...

Render parameters?....You got every little parameter dialed in perfectly? No overkill settings?

Tell us more.

Hello Dr. Jim,

What do you mean by efficiency? I've set the FG to 0,9-250-30 and bounces to one. I've also turned my GI on. Multiplier by one and 500 photons.
This is just a test. I've also tried without GI and the pic is not as bright.
As I said it is a store with lightpanels in it. I've the panels self illuminated and placed some lights behind them to make them look good as if they gave light. I'v' used photometrics? I guess this is a good way to go about no? What else? Ah yes, all of my materials are ARCH & DESIGN.

Here is a draft from a previous render...

What do you think?

are you using lights behind the signs at the top of those displays? I'm sure you could something very close to that effect with some self illumination and a map. I think others here will have better suggestions, I rarely use arch/design.

No idea what you are doing in that image...but it should NOT take anywhere near that long.
91 lights???? Why do you have 91 lights? Just because in reality a light panel might have 10 flourescent bulbs behind it does not mean you need to build it that way in 3D to acheive the look.

As far as your render settings go....I do not use MR, I cannot help on that....maybe others will chime in.

well carrrott09, I tried the sel illum map but it didn't give this bright effect at all. What materials do you use?

Dr. Jim, yes I tried to achieve the effect of fluo lights. How would you do it then?
