Join Donovan Keith for an in-depth discussion in this video Grounding objects with ambient occlusion, part of Production Rendering Techniques in Cinema 4D.
Ambient Occlusion is a way to add in small detailed shadows to objects that have otherwise softer undefined lighting.…This is something that you'll often run into when you're using a radiance cache global…illumination and also sometimes when you are using Ambient Lights, which are typically…something you should avoid unless you are going to use Ambient Occlusion.…Here is an example of an image with just Ambient Lighting and here is an example of an image…with that same Ambient Lighting now with Ambient Occlusion.…
Let's compare this to a similar render that's using a global illumination based solution.…The colors don't match perfectly, that's because it was quickly set up, but I assure you, you could…get the colors to match more closely.…Let's take a look at the difference in Render Time.…To get this level of fine detail with the Global Illumination, was 4 minutes and 36 seconds.…To get the same effect using Ambient Illumination was only 34 seconds.…So this technique at least in limited circumstances can really save you on render times and also…
