Expand description

A light that emits light in all directions from a central point.

Real-world values for intensity (luminous power in lumens) based on the electrical power consumption of the type of real-world light are:

Fields§

§color: Color§intensity: f32

Luminous power in lumens

§range: f32§radius: f32§shadows_enabled: bool§shadow_depth_bias: f32§shadow_normal_bias: f32

A bias applied along the direction of the fragment’s surface normal. It is scaled to the shadow map’s texel size so that it can be small close to the camera and gets larger further away.
