A DirectionalLight is a light aimed at the world from infinitely far away so that all of its light rays are parallel and point in the same direction
  • DirectionalLight {
  • ambientIntensity 0 # exposedField SFFloat
  • color 1 1 1 # exposedField SFColor
  • direction 0 0 -1 # exposedField SFVec3f
  • intensity 1 # exposedField SFFloat
  • on TRUE # exposedField SFBool
  • }
