It hasn't been hard to produce realistic-looking skin in computer-generated movies, but it's much harder to do that in the context of a game running live on your console or PC. That trip to the uncanny valley is going to be much easier in the near future, though, thanks to the impending arrival of Unreal Engine 4.5. The gaming framework adds subsurface light scattering effects that give digital skin a more natural look. Instead of the harsh visuals you normally get (see the pale, excessively-shadowed face at left), you'll see softer, decidedly fleshier surfaces (middle and right). The scattering should also help out with leaves, candle wax and other materials that are rarely drawn well in your favorite action games.
