Still not satisfied? Are you kidding? I am astonished with your answers. I have to do some tests to see why my roofs did not work, but it's just what I wanted ... Thank you very much !!!

About your comments: "Are you saying this does not work in the plan you posted if the only thing you do is build a roof": Yes, that's exactly what I say "Are you by any chance talking about that bright white spot on the ceiling.": No, I'm talking about the intersection between the left wall and the ceiling. I know it's an effort for you, but if you could remake the "ko plan" putting a roof on it and post it (I have tried several roofs with and without auto build), I think we could discuss over a valid plan instead of over plans that are not rendering fine ...

I have tried again putting a roof (a really big one), but nothing changes. ko with roof.plan Reducing the intensity of the sunlight, only makes the problem less evident, but it is not the solution if I want a scene with a vivid sunlight (in the limit, for a zero sunlight intensity, the problem disapeers, but I don't have sunlight). Could you please attach the "ko" plan file with the roof you put on it?

I have attached properly the plan files. As you suggested, if I place the camera infront of the window in the first scene (the one that was ok), it turns ko and the light bleed show up. I am using in all the scenes the generic sun and the sun follows camera option check is off. Only disabling photon mapping I get an image without the light bleed. If someone can try the attached plan files in the first post, it would be great... PD: I have to carefully read the post that you suggested because it looks really great!!! Very good job.

I have a problem rendering almost all the interior scenes that involve sun light and photon mapping. The problem is that there are unwanted lights from the edges of some objects and walls. After a lot of research, I simplified the scene to a rectangular empty room with one window: If I place the window on a wall, the photon mapping rendering works fine. ok.plan (this is the plan file) If I place the window on another wall, there are unwanted lights in the top edge of one wall. ko.plan (this is the plan file) I haven´t found a solution (roof, other lights in the room...) beyond not using photonmapping, so I think there's a bug in the photon mapping algorithm. I hope that some advanced user can help... I atach the files with the proof of concept. Thanks in advance, Jael
