Light color. Multiplied with intensity for final contribution. Tinting can create mood effects (e.g., red for emergency lights).

Direction the spot is pointing (should be normalized). Points along the cone's central axis.

Inner cone angle (radians). Full intensity within this angle. Creates a bright, unblurred center region (hotspot). Use MathHelper.ToRadians(degrees) for degree values.

Peak intensity at the light source. Light attenuates toward zero at Range distance. Higher values = brighter, more concentrated light.

Outer cone angle (radians). Intensity fades to zero between Inner and Outer angles. Defines the full extent of the cone (penumbra). Should be larger than InnerConeAngle.

World position of light source (tip of the cone). Light direction and attenuation calculated from this point.

Maximum range of influence. Light attenuation falls to zero at this distance. Defines how far the spotlight cone extends.

Shadow settings. Spot lights use standard 2D shadow maps (perspective projection).

Physical radius of the light source.
