Still unable to render scenes with lights after 16 GB ram upgrade
I just upgraded to 16 GB on my macbook pro, and I’m seeing a huge improvement in speed/performance. However I’m still unable to render out a Comp that contains lights. I’m trying to export a 10 second Comp that uses 3 point lights (all of the objects accept light and cast shadows). In my comp there are 15 or so Collapsed precomps, and some text. When I go to render, the render queue says about 25 hours for a 10 second render (but there’s no progress at all). Does anyone have a suggestion or know a way around this issue? Thanks in advance!
My MBP:
Processor Name: Intel Core i7
Processor Speed: 2.3 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 8 MB
Memory: 16 GBScreenshot of my Video/Multiprocessing settings-

I suspect something other lack of RAM is the issue.
I have no trouble rendering with many lights on my MBP i7 also with 16 GB, nor on my MBP Core 2 with 8GB of RAM.
Its slow but not 25 hours. Check your Comps, what else have is going on, effects, dimension of footage, dimensions of final render, output module etc.
I’m pretty certain it isn’t the lights.

Thanks Dave, your input’s always appreciated.Turning Multiprocessing off still takes a long 20 hours, but at least its actually moving (as opposed to 25 hours and no progress at all).
However it’s still shocking, I’ve cut the scene down from 10 seconds to 4- so that’s 20 hours for a 4 second scene using only 3 lights. I’ve been doing render tests for days without reaching a decent solution, still trying different things.Interesting stuff you mentioned about the computation during render- “With settings like that, you’re asking AE to do a huge amount of computation.” Did you mean shadow casting and collapsing pre-comps settings? I can probably bring everything into the main, and do without the collapsed precomps- would that change anything?
Also for the first time ever, my render seems to pause when my computer goes into Sleep mode. When I “wake” the computer I notice the elapsed time is the same as just before the computer went into Sleep mode. So i have to change the settings for my computer not to “sleep”. Never happened before this render. Sound a bit odd?

Hi Brian,
Thanks for your input, I’m not really using much effects- The collapsed precomps contain mainly shape layers, text, and 1 or 2 vector artwork layers. Almost all layers in the main comp have an opacity of less than 100%. The 3 point lights have diffused shadow darkness, and all objects cast/accept shadows. All 3d layers in the main are motion blurred. I also have one adjustment layer at the very top using Magic Bullet Looks, but that’s about it for effects.
You’ve mentioned “I have no trouble rendering with many lights on my MBP i7 also with 16 GB, nor on my MBP Core 2 with 8GB of RAM.” Do your objects usually cast/accept shadows? I’m starting to think this problem’s caused by layers accepting/casting shadows.
I still havent figured out a good render solution, but still doing different render tests.
