Hey guys -

I've been working on some 3D stuff in CS4 (I know it's old -- I don't use it a lot) and keep getting that 'Out of Memory' error when rendering. Memory is cheap and easy and I'd get more, only I'm not convinced that lack of memory is causing my problem. I have 16GB of RAM in there now and notice that, while rendering, the render window says it's only using 8% of my RAM.

I've gone through the settings menus, tried different combinations of memory allocations and even did the "secret menu" thing. Nothing really made a big difference.

So I have two questions:

1. Why does AE say it's only using 8% of my memory while rendering when I have allocated almost all RAM to AE?

2. Has there ever been an "Out of Memory" case solved by actually adding memory?

Thanks ahead of time for any info and insight.

AE 9 is a 32-bit application, and can only access 4 GB of RAM for any single instance of AE. If you have a 64-bit OS, it can access more via multiprocessing.

This trick may not help if you're working with extremely high-resolution files.
