Why does Blender take more time synchronizing than it does to render. Does anyone know a solution to this problem?

This may not be a solution, but does help me speeding up the animation render.

In my case one object needs a lot of time to synchronize. While this is happening the computer is not really busy. To use these ressources I started a 2nd instance of blender (background render at the commandline) starting rendering the 2nd half of the animation. This increased the render time of both render instances just a little bit which in general accelerates the animation render almost by a factor of two.

I don't know how that is influenced by the specific scene and the hardware used. But for me it worked pretty well.

  • $\begingroup$ Good idea, could you provide some insight on when or why the synchronizing takes long. $\endgroup$ – Leander Jul 27 '18 at 15:03
  • $\begingroup$ At the moment I don't exactly know what blender is doing when synchronizing an object. It probably has something to do with the number of vertices and maybe with the texture applied to the object (and UV unwrapping). This is probably a good new question. $\endgroup$ – Phann Jul 27 '18 at 16:23
