Hi Everyone, I'm setting the lights in my scene. I'm using the regular lights instead of the spotlight. Initially, I put the light in origin. My object is at:

object:translate(-0.75, 0.25, -10.0)
object:rotate('y', -20.0)

Here's how I set up the light.

If the light is positioned at the origin, I can see the lighting effect at the object very well. However, if I move x or y or z axis a bit, the lighting effect disappear immediately. However, if I use spot light, the problem disappears. Based of my understand, the regular light should light up the entire scene(like the sun) isn't it? Thanks!
