testing texturing and lighting

Since I have never truly used Unreal Engine until now, I decided to start to mess around with a few already made textures that are put into the engine by default. And also started to mess around with a few lighting methods. Since the only modelling software I have ever used is 3DS Max, I have never really been able to understand how lighting and shadows work in 3DS Max. However, in the Unreal Engine, the lighting engine is so much better and so much easier to understand. Designers can simply drag and drop the light source that they want to use for there level, and also decide what colour the light is and how bright it is.

The main issue I faced when messing around with the lighting and textures, was what type of model would I use to fit the type of light source for my level. Would I use mainly candles, and torches. Or maybe just go for a simple window light source, and use the Sky source tool to play around with the full lighting off the level by generating off the sky sphere.
