 After the G-buffer is complete, light volumes (spot and point lights) or fullscreen quads (directional lights) will be rendered to a light accumulation buffer to calculate the diffuse and specular light at each opaque pixel. Specular light is stored as intensity only. Stencil compare (AND operation) with the 8 low bits of the light's lightmask will be used for light culling. Similarly to forward rendering, shadow maps will be updated before each light as necessary.

After this rendering proceeds to the pre-alpha pass, transparent object rendering pass, and the post-alpha pass, just like forward rendering.
