Been driving myself nuts with this for long enough now so time to ask for a little advice.
I have been trying to add an area sky luminance to the window in the attached picture but I am getting lost in all the settings.
I have no problem actually adding a luminance to the object but from there it all goes wrong.
The reference manual has not been very useful for this so can someone point me in the right direction.
all I am aiming to do is to cast a shadow into the room.
the sphere was only added so that I could see if it cast a shadow from the window.
Thanks in advance
