SE Screen-Space Shadows
SE Screen-Space Shadows provides screen-space raytraced shadows for directional lights for sharp, detailed contact shadows. It can capture details in shadows that would otherwise be missed using traditional shadow maps alone.
This effect requires DX11 or OpenGL 4.1. It is not compatible with OpenGL ES and won’t work for WebGL or mobile platforms. It is compatible with Unity 5.4 and 5.5. SE Screen-Space Shadows requires the deferred rendering path.
In addition to providing better contact and self-shadows, this effect can be very effective for fields of grass or small detail objects like rocks where rendering these objects to the shadow map would be very costly.
