Duplicated COMPS taking ages to render

[Lachlan Fletcher]

Hey Dave thanks for the response,

Sorry when I said I changed something I just meant the camera movement. I used that long Comp as a base and made some smaller comps out of that, focusing on different aspects of the item I animated.

Here is an example of what Im doing. The animation is at the start.

Thanks again Dave

Do you now have multiple copies of the comp, all stacked and nested together somewhere? If so, that could explain your render issue: each instance of the comp needs to render separately.

Any chance you can post a screenshot of your UI and timeline?

[Dave LaRonde] “If you’re NOT using multiprocessing, that’s good: otherwise, you could have bad memory / processor allocations, which slow things down.”

FYI, the ray-tracing renderer doesn’t use multiprocessing like the classic 3D renderer does. The ray-tracer will render a single frame at a time, but it will render it using all cores.

If you are changing the camera animation do you have motion blur switched on? I don’t know how the motion blur is calculated but it might affect render times.

Great point. Ae uses multiple samples for motion blur, and that’s driven by the quality slider in Composition Settings > Advanced > Renderer: Options. That dialog box will tell you how many motion blur samples will be used with the current quality settings.

HEre is a screens shot as Walter suggested.

Sorry guys thats an image of the full sequence not the short versions. Here is the Short comp.

I would like to say by the way, that I really get alot out of this forum. It has taught me so much as Ive been learning ae over the past year, so thanks you guys especially the regulars. Im sure all the other forum readers feel the same too.

Thought I might share with you my Pref page to see if there might be a prob there. It says actual cpus used 0!! That doesnt sound right. You can probably tell Im on a steep learning curve & bing patient for a new machine with a good graphics card etc.

I’d suggest changing your multiprocessing settings to match the recommendations [link]: leave 2 GB for other applications and reserve at least 1.5 GB per background CPU. I’d also leave 2 CPUs available for other applications.

Since your system is somewhat RAM-limited, you may sometimes get faster renders with multiprocessing off than you would with it on.
