Description

Before directional light screenspace shadow mask is computed.

Directional lights when using non-mobile shadows "gather" shadowmap into a screenspace buffer and do PCF filtering during this step. Later on actual object rendering just samples this screenspace buffer.

This light event will execute command buffers when the screenspace mask render target is set and cleared, shadow cascade parameters are set, but the shadow mask is not computed yet.
