LightGlobal

The LightGlobal class represents a global directional light source such as sunlight or moonlight. It includes a view angle parameter that controls the softness of shadows based on the distance between the shadow caster and receiver. This class also provides a comprehensive set of parameters for configuring Parallel-Split Shadow Map (PSSM) behavior to ensure constant shadow density across large scenes.

info

Ray-tracing based shadows are free of shadow-map related density and precision artifacts.
