Nick Campbell, aka "Greyscale Gorilla", gave this presentation at our January Chicago C4D meeting. He went over the grounding for realistic lighting in Cinema. If you have every had trouble with lighting in Cinema or any 3D application, this is a must watch!
DISCLAIMER: We had a little issue with the screen capture so it does not always act in real time, this is something we will for sure get fixed for the next meeting and we apologize in advance. But to understand what's going on it is not necessary, enjoy!
