Gatelight thesis
Good news I think. I made two placeholder lanterns.
It seems to me that the polygon plane with the alpha masked frontgate texture recieves as much light as the fence left and right of the gate which are geometry with mass.
Didn't know this and I'm well pleased to not having to model the gate hehe.

(Sorry for high quality jpg, but I want to show the light as well as possible.)
