Rendering a Single Frame Faster with Multiple Computers

  • Software:Blender 2.71  ·
  • Difficulty:Advanced

When you don't feel like waiting 5, 10, or 20 hours for a render.

You're probably aware that multiple computers can be used to drastically improve the total render time of an animation. But what about those of us who don't render many animations - can the same idea be used for single frames? Architectural visualizers rejoice - Yes we can! This technique is commonly referred in several ways: distributed rendering, bucket rendering, network rendering, and parallel rendering. Most render engines, including Cycles, render your image by dividing it into small blocks. These blocks are called "tiles" and on a single machine they're divided up among the cores of your CPU. So the more CPU cores you have, the sooner your render will complete. Typically with distributed rendering, those tiles in addition can be divided among multiple computers and their cores (which is called a renderfarm) to greatly improve render time. We can't do this quite yet with Blender and Cycles but we can achieve the same goal with a work-around. That's what you will learn in this video. The yellow resin shader used in this video is available on the Blender Market. CC Music Attribution - "260809 Funky Nurykabe" by spinningmerkaba
