This page gives you an overview about lights at a glance.

Wait, this isn't what I want!

• To learn about shadows in the world, check Environment: Shadows

• To learn about shadows for equipment items, check Meshes, Shadows, and Shadow Meshes

• For a guide how to add lights to AMM props, check AMM: Light Components

• For a quick overview on lights and their properties, check Cheat Sheet: Lights (currently WIP)

• If you want to learn more about blocking light, check Occluders and light blocking

How do lights work?

IDK either! But maybe someone edits the wiki :/

Directional lights

Cyberpunk uses three types of lights:

Point light

The light is a sphere and is equally bright in every direction

Spot light

The light is a cone. The sharpness is defined by its inner and outer angle.

Area light

The light is a square (like a light panel).

Light attenuation

Their are two options for light attenuation listed as LA_InverseSquare and LA_Linear light attenuation is the falloff of luminance away from the point of origin as the photons spread out \

LA_InverseSquare

Inverse square root is the default option and the physically accurate one, This should generally be set by default unless absolutely necessary. LA_InverseSquare models the falloff of luminance according to the inverse square root law.

LA_Linear

Linear simply directly drops light luminance according to the set radius of the light. this setting can make a light more obvious or bright overall however does so at the cost off functioning unnatural and potently appearing too bright at distance.
