Using Sky Portals for interior global illumination (GI)

Without a doubt getting a believable exterior lighting solution in Twilight is a very achievable, dare I say even easy, task to accomplish, especially if we use the Physical Sun and Sky for our scene lighting and then just rendering over to one of Twilight's progressive render presets. The problem with rendering interiors, however, whether we're using the sun and sky or indeed any exterior light source, is that we are always going to struggle a little bit to pull enough light energy into our interior environment.

Anything then that we can do to squeeze a little bit more quality, a bit more light out of our render engine, that's at least going to be worth considering. What we want to do in this video is just show you how you can turn some simple SketchUp planes into Sky Portal objects. These can help our interior lighting solutions by really telling the render engine where to focus its global illumination sampling efforts. The first thing we need to do is take a look at how ou...
