big stills in 3d comp
I’ve read other discussions of the problem of hi res stills in AE comps, but I haven’t seen a solution to the problem that’s plaguing me now. If anyone can offer any ssuggestions, I’d be grateful.
I’ve got a comp filled with nested comps. (right now there are 8, but ultimately there will be 16 or more).
The nested comps are large photoshop files with two layers ea. The files are 300 ppi, & most are approximately 720 X 480.
At a certain point each nested comp, moves forward in z space, overtakes the camera, and disappears. So even tho they start out at 30 or 40% scale, they become huge, and detail is very important.
Also, Very Important, I need to be able to see the relationship of each nested comp to the other as I manipulate them. Each one has a different shaped alpha channel, & I can see the others thru that channel.
Things go very very slowly.
I’ve got an 8 core with plenty of ram.
I’ve got my settings as follows:
Open GL, multiprocessing enabled, Max RAM cache 30%
Max memory usage 120%
If I try to enable disk cache I invariably get a crash.Can anybody suggest any ways I might make things go faster?
I can’t work smaller and extrapolate to settings for larger files. I can’t do math. At all. Although if someone could give me a simple all-purpose algebraic type formula…I’d be grateful for any help.
I’ve been soloing two or three layers. That helps, but I can’t see how other layers are viewed when I do that.

HI,
I would try:Turning off open GL.
if you enable opengl for previews ae will not use multiprocessing to render previews, they are not compatible renderers and the opengl render engine override the multiprocessing settings. with a 8-core mac, you’ll probably find that the multiprocessing is faster than opengl acceleration. opengl can only accelerate the render of blending modes, motion blur and about a dozen standard effects, multiprocessing will accelerate pretty much all rendering.And: you should be able to use proxies for those large stills.
check the AE tutorials here on the cow.and maybe: Animating the camera instead of the stills. (if you can)
And: if something like photoshop is running and it has a big ram allotment, try quitting that. Sounds funny but I had to do this last night under a similar situation.
Good luck,
B
