Hey everyone, I'm having some serious frustrations with Cinema 4D R11.5, But let me give you my system info first and lets see if we can find out what dumb problem i'm not seeing. Model Name: Mac Pro Model Identifier: MacPro4,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 2.93 GHz Number Of Processors: 2 Total Number Of Cores: 8 L2 Cache (per core): 256 KB L3 Cache (per processor): 8 MB Memory: 14 GB Processor Interconnect Speed: 6.4 GT/s Boot ROM Version: MP41.0081.B07 SMC Version (system): 1.39f5 SMC Version (processor tray): 1.39f5 SO here is my problem, I'm rending a 3 Minute, 6500 frame Audio+motion animation using multiple effectors and mainly the sound effector. I'm rendering 64 Threads 2000 MB Polygonal Memory 720p HD Video output to Quicktime Outputting to my "design" HD which is not my boot, has 600GB available room. My problem is after about 60-120 frames, C4D stops and tells me I'm out of memory when in fact besides the obvious CPU stress it's putting on my system, it's only using 40% of my RAM, and 1% of my HD. It's killing my week, I'm not on a deadline but it's part of my motion portfolio. If needed I'll upload the .c4d file and see if it's just my system. I'm not sure if I have Snow Leopard/myC4d setup entirely correct, but I dont see any problems rendering stills. I'm about to switch to another 3D bundle if I cant fix this, so anyone else suggestion new software is welcome. Mac/Winblows.
