Way too heavy Workload with 3d-effects. Need an hint !
on Jan 20, 2016 at 9:24:11 am

Hey guys,
i study Motion Design in Berlin and we just started to work with 3D-Effects. In my project, Santa Claus runs in 3 different landscapes(e.g. with mountains in the background) from left to the right side. The camera "swings" from 1 landscape to next one, so that the 3D-effect is created.

My problem : I cant even switch the seconds in my project and see a frame without waiting like 20 seconds. Rendering takes up to 15 minutes for 1 second! I know that there has to be a mistake, because my professor showed me a similar project and his notebook was able to handle the workload waaaaaaaay faster than my pc at home ( i5 6600K @4.4ghz , 16gb ram, no graficcard )

My question : Is there any option i turned accidentally on ? Or can i turn off some effects i dont need ?
Every single hint is welcome :// !!!

Btw. it is not real 3D. It is "2.5D" ( some kind of 2D which looks a little bit like 3D cuz of a few effects.)

What version of AE? Do you have multiprocessing set up? Do you have motion blur on? Can you lower your quality to preview? Can you prerender parts of the comp?

[Niklas Meinert] " Or can i turn off some effects i dont need ?"

We would need details on what effects you have.

15m per 1s might not be that bad, depending what you've got going on in your scene.

Here are some things that might slow your render down:
  • Using the ray-tracing renderer instead of the Classic 3D renderer. Check your composition settings (Ctrl+K, Advanced tab).
  • Using Depth of Field in your camera settings.
  • Using motion blur.


Things that might speed your prof's render up:
  • Previewing at reduced resolution.
  • Using the disk cache.
  • Multiprocessing (Ae CC 13.2 and previous).

Version: 13.6.1.

Yes i have ray-tracing activated, but i think i need it ? (Ray-Tracing Quality 3)

And motion blur seems to be activated for the first level ( not sure if the word for it is level in english, sry).

Disk-Cache is activated with a max of 23gb.

No idea, where i can find my settings about Multiprocessing :(!

I'm still in my first semester and not really familiar with all those settings.

Huge thank you both for the fast answer!

[Niklas Meinert] "Yes i have ray-tracing activated, but i think i need it ?"

Well do you actually need it? We still do not know what you're actually doing. It's insanely slow if you don't have a CUDA supported graphics card and there's a lot of limitations that the normal 3D renderer doesn't have.

So i guess its the ray-tracing.
What i'm trying to do is :
i've drawn 3 landscapes and a santa claus ( every landscape is made of 3 levels: ground where santa walks, mountains behind him and a cloudy sky behind the mountains). i've animated santa, so he can walk. santa walks from 1 landscape to the next one and every time he passed 1 landscape, the camera "swings" to the next landscape ( with keyframes).

When i switch to normal 3D renderer i'm just able to see the background(sky)... when i switch to ray-tracing, i can see my whole project ( but its so freakin slow ).

I just have 750ti gpu and ae doesnt supports 750ti's.

Thanks for your help!

If you want help, you'll probably have to show some screenshots of your entire UI so we can see what you are seeing.

We'd need to see more of your timeline to help, but there are a few things that affect layer intersection in the Classic 3D renderer and could cause the behavior you're seeing:

[Niklas Meinert] "Yes i have ray-tracing activated, but i think i need it ? (Ray-Tracing Quality 3)"

Unless you need to extrude/bevel text or shape layers, bend a footage or comp layer, create reflection/refraction through materials, or use a global spherically-mapped environment layer, you do not need the ray-tracer.

Unless your comp requires one of these specific features, switch to Classic 3D and your render time will probably improve dramatically.


[Niklas Meinert] "No idea, where i can find my settings about Multiprocessing :(!"

It doesn't exist in Ae CC 2015 (version 13.5 and up). The Ae team has been re-working the 20+ year old architecture of Ae to lay the groundwork for some big performance improvement, but it's not all there yet.

Note, however, that multiprocessing has no impact on the ray-tracing renderer in any version of Ae.

I got some help and everything is working fine now ! At least, my problem just came from the ray-tracing! i forgot to switch every layer to normal 3D... after i fixed that everything worked as it should be.

Thank you very much :)
