Is it documented anywher ethat as you increase the Angle End of a spotLight, the shadow cast by it decreases in sharpness? It appears that somewhere between 140 and 150, the shadows cast and the outer perimetre of the light's area of effect begin to bleed into one another to the point where you can no longer see the cast shadow, and the overall effect of the light is merely dimmed. Crap crap crap. That means it's going to take more than 4 lights to make an omnidirectional. I was hoping an equalateral pyuramid would do the trick. But there needs to be about ten degrees of overlap, and while a d4 shape will provide 120-degree ranges, for that overlap there needs to be a 140-degree angle, which means that at that point the shadows fuzz out.
