Hi, I'll post a video below of what I am seeing but first I will try to explain. My aim is to replicate a light source such as a laser. I have an enclosed area in 3D space (without light the render is black) that I am trying out different types of light source in. I can see the directional light to work if I cut a hole in the wall and have it shine from the outside in. When I try to bring it inside it doesn't illuminate anything at all. www.youtube.com/watch ;feature=youtu.be Thanks in advance, Josh
