Join Donovan Keith for an in-depth discussion in this video Optimizing material settings for global illumination, part of Production Rendering Techniques in Cinema 4D.
Global Illumination calculates the bounced light in a scene.…However, not all objects are created equal. Some are more likely to contribute light to a scene than another.…And if we tweak our Material settings, we can tell CINEMA 4D to focus on those objects…that are most likely to add light.…What we have here is a geometric structure with some deep recesses.…And inside of those recesses are individual polygons that have a material with luminance turned on.…Let's just go ahead and render with the default GI settings.…We see that we get some samples, but they're very blotchy.…
And that's because--as we learned in our video on QMC--the samples get sent out in every different direction sort of randomly.…And sometimes they're going to hit one of these lights over here, but sometimes they…won't, which is why we see a lot of contrast on the interior where there is a pretty good…chance of hitting a light and also not hitting a light.…Let's go ahead and tweak our material setting to improve the final look here.…
