Need advice for light portal

[Torsten]

Hey guys,

I am wondering how i should use the lightportals in my specific scene. I attached one of my windows, the scene has a total of three of these.
Should I cap the entire window at once? or will that not be smart because of the horizontals and veticals inside the windows? What is the best way to use the lightportals?

Hi, capping each of the holes would be probably most efficient (though it would require testing) but this way should also work (pic) . Generally it should be easy to test which version is more efficient, sometimes it depends on the scene.
