Saving render time | Fast Global Illumination for beginners

Jamesy ·

James Crowther explains how to use Fast Global Illumination in Blender.

I did another tutorial on render optimisation, this time looking at fast global illumination approximation. This tutorial is aimed at beginners to intermediate blender users and covers the basics of what Fast GI is, how using it impacts your scene visually and how it affects render time.

Using this feature well can get you some significant savings in render time. There are changes to your image, particularly in the levels of brightness, but you can get a result that is close enough that it can be difficult to tell.

I'm a software engineer, I've worked on numerous technologies over the past 10 years. I started out working on full motion flight simulators and then worked with embedded systems. I now work on building an add-on to support rendering using multiple computers over internet/local networks.I started using blender in 2009 and have done small projects with it since then, however, crowd render, our network rendering add-on is by far the biggest adventure with Blender to date.
