In this beginner friendly Blender guide I’ll show you how to setup Lightgroups so you only have to render once and can then change the lighting setup of your scene after the fact in the compositor, without having to re-render the scene over and over again.
I’ll guide you through all the steps of how to set up the groups, assign lights to the groups, composite them back together and then control every light source individually to make different scenarios.
I’ll finish up with a quick compositing for realism.
