Render time is extremely excessive
OK, here are the specs I’m working with first off:
My machine:
MacBook Pro
2.6 GHz Intel Core i7
16 GB 1333 MHz DDR3 RAMThe Disk Cache:
LaCie USB3 External SSD (200 GB allocated for cache)Details about my AE project:
AE version: CS6
7 minutes duration
1920 x 1080 (1080p) resolution
Classic 3D environment
17 light layers
5 cameras
All other layers are either shapes, solids, pictures, or pre-compsOK, so I pre-rendered the portion of my comp that used a complex expression to slow down and speed up rotation, so that should have helped overall render times greatly.
I also moved my entire project (all comps and nested comps) to Classic 3D, mocking extrusion with 6 flat planes where necessary.
When I went to render my main comp it said it would take 854 hours. How on earth?
What am I doing wrong? What configuration settings should I key in on? Shouldn’t Classic 3D be much faster to render than Ray-traced?
My project is coming due, so please please help! Thank you.

Sigh, here is a screenshot of my render queue. 1034 hours for a JPEG Sequence?!

Todd, see my screenshot above. The help I received in that thread, to date, has increased my render time exponentially. That’s why I’m following up.
There MUST be a quicker way (under 48 hours) to render a 7-minute long movie that isn’t even Ray-traced.

6 minutes a frame, 17 lights and 5 cameras? How many layers do you have in there?
Are you sure that none of your precomps are still set to ray-tracing?
What are your memory and multiprocessing settings?

Also, I see you’ve only rendered a single frame so far. With multiprocessing enabled, it can take some time to start the background processes and load the project — a lot of time if the project file is big.
As a result of this initial delay, the early completion time estimate can be way, way off. If 5:30 of that 6:00 was starting up the background processes, your actual render time may not be that bad. Does the render speed pick up any after the first few frames?

No, the render time got worse 3 frames in.

Here are my 3D settings:

With 12 GB available to Ae and 3 GB per background process allocated, I’d expect to see 3 or ideally 4 background processes running, not 2. You should close other open apps and maybe reboot the machine.
You may consider lowering that memory allocation slightly. 2 or 2.5 GB per core may allow you to run more rendering processes unless you have high RAM needs for them.

Are you sure that every single precomp is also Classic 3D? If you have a few layers of a ray-traced 3D precomp in there somewhere, I’d expect to see longer per-frame render times.
