Area Light (Rasterization)

Note that these attributes have effect only for Area lights:

Resolution Coef.

Resolution coefficient determines how many pixels (in two dimensions, it means that if resolution coefficient is equal to 2, then 2x2 = 4 pixels will be used) will be averaged into one virtual point light (VPL).

Number of Lights

The maximum number of virtual point lights (VPLs) that will be generated and used for lighting.

Shadows Coef.

Coefficient estimates how far VPLs have the same shadow map. Zero means that each VPL has an own shadow map. With bigger numbers you save time and memory for lower number of shadow maps but decrease the quality.
