Subsurface Scattering in Unreal Forward Renderer (2017) – YouTube link
This talk discusses how subsurface scattering is implemented in Unreal Engine’s forward renderer. Because UE4 implements subsurface scattering as a screen space effect, it wasn’t available on the forward path by default, so a new technique had to be implemented, and one that had to still work with the UE4 material system and editor.
