In my so far… short… experience with Cinema 4D, I have found that one of the hardest things to do for a scene is to light it properly. So I discovered the Advanced render module and Global Illumination. This made lighting more realistic, and easier. But, it adds sometimes HOURS to the render time. But it is usually worth it.
But, there are always people out there who will make things easier for you…. (Please don’t take this in all ways)
For example, the guy over at Hello Luxx has provided everyone with some amazing GI presets!
So, I have copied the download here. And below are some screenshots of a basic cube with cut outs using the presets… Amazing!
