Due to the nature of VR, the resolutions are often very big. We were rendering 8000x4000. We working working at quarter rez or smaller, happily rendering at half-rez to see our revisions. Big mistake. When it came time to render full-resoltion, most of our machines were incapable. Among our 30 Macs we had just 4 that could do it. Weirdly, we had other machines with the same graphics card and everything else that couldn't. I guess we were lucky to have the 4, or else we couldn't have rendered. I'd guess having as much memory on the Graphics card as possible would improve your chances of being able to render, but this business of not falling back to the CPU is untenable. Brendan |
