Join Donovan Keith for an in-depth discussion in this video Utilizing Irradiance Cache global illumination, part of Production Rendering Techniques in Cinema 4D.
Irradiance Cache Global Illumination is perfectly suited to architectural renderings.…By sampling the bounce light in parts of an image and smoothly blending between the samples,…it gives you all of the visual benefits of bounce lighting with a minimum of expense at render time.…Let's just take a look at a simple architectural interior.…What I've got is a polygon objects for my walls, some simple chairs made out of cubes,…a few picture frames, and then also a window right here.…I am going to take a look at the scene from outside just to show you how it was constructed.…
Click on the icon to the right of your exterior camera to take a look, or rather,…just hit the H key on your keyboard.…What this will do in this Exterior View, and what we see is that we have got some colored…walls, and actually transparent window, and outside we've got a sky that is completely…white, and this is the only source of illumination in our scene.…Or at least it will be once we start using Global Illumination.…So let's go back to the Interior Camera by clicking.…
