I've been using CC3 for years but never very effectively as I've never taken the time to learn it properly. I've finally started making a real effort toward that end and am really enjoying some of the more advanced features that version 3 added. Thanks to the wonderful folks in the PF forums, I understand point lighting now. It's very cool.
Here's a sample of some corridors I'm playing with that use numerous point light sources to produce glowing patches of moss. It's not really a map, just a sample bit I came up with during my experiments.
