The computer used is a 1st gen unibody macbook pro (core2duo 2.4ghz / 4gb ram), by no means a fast machine. The 8 hour render is simply an “overnight render” where the settings are all bumped up and I just let it go. Removing the liquid from inside the bottle greatly reduces the scene render time.
What I learned from this exercise is that longer render times seem to make little difference in the outcome. I’ll need to experiment more to find the best balance between quality and efficiency.


8 hours to render 1300×900? what kind of monstrous render setting do you use? whats your computer spec?
thanks for the question, see my clarification in the post. I’ll also posting the render settings I used when I can check. As I recall I ~doubled all the default ‘advanced’ settings.
