UE4: Lighting mini-blinds

Mini-blinds with lined shadows

Objects in scene are painted with the shadows
from the light function

Blueprint class with plane object and lights built in.
contains a non-shadowing point light, and shadow casting spotlight
which has the light function defined.

The blinds photo is added and set to give emissive light,
there is also a normal map I was testing, more useful when
not emitting light.

The spotlight near the blinds has a special material
 added as a "light function". This makes the lines masked out.
