We recently stressed our renderfarm. A lot. For the feature “Faunutland and the lost magic” we created 280 shots and most of them (229 shots) had 3d rendered set-extensions. Because we love data, here you go: We rendered 31.900 frames, thats over 22 minutes of VFX! Each shot were itterated 3 times so in total we rendered 95.700 frames. Average rendertime was 20min/frame. That gives us 1329 days of CPU time. Luckely we could use more than one CPU. Read more on our case study here.
