Making a light 'soft' in a 3D scene

[Regina Henschel <rb.henschel@xxxxxxxxxxx>]

Hi Armin, hi all,

a light can be 'harsh' or 'not harsh' (that means 'soft') in an extruded 
custom shape. This is independent from the material property 'specular'. 
A 'soft' light is rendered in MS Office, as if the light has a wider 
emitting area in real world.

The UI of our 3D-Scenes does not have something in this kind. Is there 
in the internal handling of 3D-Scenes something, that can easily be 
extended to produce such light effect?

Currently I experiment with using additional lights in the 3D-scene that 
is used to render an extruded custom shape. But that emulates the effect 
not really good and means a large effort.

Kind regards,
Regina
