Q: When I try to render models with different types of lights, the point light and the directional light work correctly, but the spot light doesn't. A: The cone of light needs to touch a number of vertices for any effect to be seen. If the light is attenuated, it may have insufficient intensity when it strikes the surface. The cone of light also needs to be wide enough to cover a significant area of the object being modeled for the renderer to draw a reasonable effect. |
