Blender 3D: rendering an animation across multiple computers

Quick tip on rendering 3D animations on more than one computer to speed things up but without a proper setup or render farm or similar:

I’ve been using Dropbox for all kinds of syncing and this is another useful one:

If you have multiple computers set up with the same dropbox path and they are in sync, you can simply open the same .blend file on all of them and uncheck “Overwrite” and check “Placeholders” in the Render -> Output settings. Then render into your dropbox folder and each computer will see the placeholders and move on to the next frame during rendering.


Sometimes you might get some overlap and 2 computers rendering the same frame but it’s no big deal because it simply shows up as a conflicting copy on all computers and is quickly cleaned up. Overall it’s still a huge timesaver.
