Finally, a finished shot! I think... These are the titles for the beginning of the film and after tweaking the noise in the volumetric lights (the clouds for non-geeks) I was able to get the render time on my MacBook Pro down from 90 hours at quarter resolution to just 10 hours for 720p HD. I think it might still need some little details, maybe dust motes or lens distortion but I'm pretty chuffed overall, what do you reckon?
