I was watching a couple of videos on realistic interior designs, and I look back at my scenes and the lighting is horrible compared to the ones on you tube, I was wondering how can I make realistic lighting when working on an interior scene?
Hello Edited Runthrough,
There are a number of things that can influence the realism of light. Everything from how the lights are set up, to techniques for lighting, to the material and what the light is actually casting on.
