directional light

[jammer64]

Yea, spotlight is a directional light.

well, it's not quite directional in the way i mean. and i mean directional light such as sunlight where we don't have single point light source, just parallel rays. spotlight here is just like pointlight, the only difference is limited angle and shadow casting. besides using spotlight as sun gives really poor results as increasing the distance from light to object results in progressively worse shadow calculation.
