True volumetric godrays, like in Far Cry 4?

Has this sort of atmospheric effect been added to UE4 or is it something we will see in the future. The godrays demonstrated by the directional light in a scene don’t look that spectacular and don’t have a 3D presence (they turn off when you look away from the sun).

Far Cry 4 had really good god rays provided by NVIDIA. Will Epic make something similar?
