Cached Shadow Map Solution for Unity

Cached Shadow Maps

Cached Shadow Maps is a unity package for caching shadow maps on unity's built in lighting system, storing them (while valid) for later use effectively reduces the number of shadows casters to be rendered each frame. This include automatic recomputation when a light source context is detected to be dirty.
