Noob question about rendering and memory


I’m a noob at this and I’m trying to learn as much as I can about 3D modelling. I’m not even close to be in a situation where I need to do this, but I would like to know.

I’ve read in some thread here that if your whole scene doesn’t fit into your GPU ram rendering will fail. But does this apply if you chose to use a CPU based mode of rendering?

Or is it it possible to split a very complex scene in smaller par and render them individually to be combined later in a final scene?

How can you render a very complex scene without spending mucho $$$ on a multiple titan GPU or Quadro workstation?

Hi, if you render on CPU you can use your full RAM (- System).
The “Pro´s” try to reduce memory usage as much as possible or render different passes to mix later in compositor.
You have a very good system but keep in mind the latest Blender Movie is rendered on a system with 4 x double 4 core XEON + some single i7 slaves IIRC and they need weeks to render.
I know from Octane (also GPU render engine) forum there are many user with 4 Titan or 4 GTX 690 only for stills.
You can make beautiful pictures with your systems, start blending. :slight_smile:

Cheers, mib.

Thank you for the explanation.
I’m still learning the interface and following an online course on Blender, but I should be able to start my first project soon.
