It is hard to understand why directional lights position doesn't make sense . I mean , take 3d modelling program ,or UDK or Unity(ok that is not the same in terms of technology ) , but the light should have emission source and the soruce should have a position in 3d space ? . and the source position of DirectionalLight3D is in the center of the scene, So if my object is not offset from the center ,there is a problem , the object doesn't receive the light at all . And .direction doesn't help in this case, I was trying to tweak it too without much success . Eventually used PointLight3d.
