How can I make rectangle light “unseen” with Path Traced renderings.
I need this feature here:
See the windows at the back of the room. There is a large rectangle light right behind the window, it gives nice reflections on the floor and all.
But I want to show the enviroment outside too, trees and buildings. How can I make this light unseen but effective as light source and show the nature outside of my window, not just that white color?
