Can you render an animation in stages (I am not sure if that is the right word in english .. let's suppose we have an animation of 300 frames and I want to render the first 100 frames to PNG output at Day 1, the second 100 frames to PNG output at Day 2 and the third 100 frames to PNG output at Day 3) ?

Will this work ? Will I get the same animation when rendering the animation in one run ? And would this also be true when involving physics ? For instance fluid or fire/smoke simulation or particle systems ? Or force fields ?

At moment I use these settings for the smoke cache.

Yes, it will as long as you bake your physics first (I would recommend that it be to an external source - Make sure that you name your cache 1st). Then just be sure to set your render range in either the timeline OR the Render Panel >> Dimensions. Once your bake is done save your file and don't touch it except for rendering, and changing your range the next day.

If you bake your Cache to Disk:

  1. It will save the folder in the same file location as your blend file.

  2. You can copy both the blend file and the cache folder and start rendering on another machine for a different range if you have that at your disposal.

  • $\begingroup$ Please have a look at the edit of my question. For smoke would I have to check External ? And what is the difference between Bake All Dynamics and Bake ? $\endgroup$ – Old Man Mar 10 '16 at 17:07
  • $\begingroup$ You don't have to check External, it just makes more sense to not have the overhead of that in memory during render time. As far as the difference in baking check this one out $\endgroup$ – Rick Riggs Mar 10 '16 at 18:50
  • $\begingroup$ I saw another post that you made regarding the render times on this project (eg. 10 days), and for your sake, I'm hoping that you are able to shorten that as a side affect to this process. $\endgroup$ – Rick Riggs Mar 10 '16 at 18:54
  • $\begingroup$ if you have done the bake, should you free the bake ? Or is that one thing you should not do ? $\endgroup$ – Old Man Mar 10 '16 at 22:48
  • $\begingroup$ So when I use a NAS, I could save the bake to the NAS and let different machine render pieces of the animation ? $\endgroup$ – Old Man Mar 10 '16 at 23:12
