C4D barely touching ram?
I’m rather new to cinema 4d, I’m giving myself a crash course on it right now… a technical question:
I’m working on an 8 core mac pro with 16GB of ram, running c4d in 64 bit mode. I’ve been making some complex-ish scenes as I fiddle… (a sandy beach with sub-poly displaced water, etc) and I’m noticing as I preview render a frame, cinema 4d never wants to use more than about 1 Gig of ram, even though all 8 cores are firing 100%. I’ve got some scenes that take over 10 minutes to render the frame, but it’s barely touching my 16 gigs of ram. Is rendering just not that RAM intensive? Or could there be something wrong that’s keeping c4d from using all available resources? I’d really like to increase my render speed…
Any insight is much appreciated!

speed of render is only partly tied to memory usage. Polys take memory, image textures take memory but the killers time-wise in rendering are the calculations of light, shadow, texture and preparation for light and shadow and texture – simple example – Icosahedron sphere/editable/Matrix Extrude tool(defaults)/drop into a HyperNurb – rendertime 0 (less than a second) – add a glass texture – rendertime somewhere in the 30-60 second range likely. No more polys in the scene, no more memory usage but lots more calculation time. Add shadows, add GI, add Caustics……
Check out this page (particularly the bits about memory at the bottom) good general info.
