What are these weird light lines?

[gregoryx]

Finally starting to dial the lighting in (thank you @ceciliabr and other). I'm pretty sure the ceiling lights I'm using came from @ceciliabr and they helped me solve the mess I had originally.

But after adding them, I get this light line along the ceiling - and around the ring of the lights as well. I can't figure out where it's coming from I've tried modifying the lights but I guess I'm missing something in there.

Ideas?

I think these lines may appear when you create a photo with YafaRay rendering plug-in. It's like sun light would be able to go through the very very thin space between walls and the ceiling.
I should find a way to automatically fix that, but it's not so simple. Meanwhile, you could chose a night time in your case.

Thank you, @Puybaret. It looks the same at 2am. I'll try back to the old renderer and see if it's there still. I'll also try placing a big, black "roof" (box) over it to see if it helps.

Are there invisible light panels on this ceiling? If so, are they flush with the ceiling? If so, place them a little bit deeper (the same amount your highlighted edges are in height).

Thanks, @UbuntuBirdy. That was my first thought as well. I'm using a recessed light thing that @ceciliabr built and shared. I tried recessing it further and changing the shape of it. It /seems/ like that has to be the cause... but it hasn't worked to fix it.

I think getting rid of those got rid of the problem; but I'll have to go back and review. If I'm the only one seeing something like this, I'm clearly doing something wrong with those ceiling can fixtures.

As Puybaret said, this problem occurs with the YafaRay rendering engine.
My tip is to add a lower level and a higher level to the virtual visitor's position by displaying all the levels in the 3D view so that the floors fill these interstices.

As explained here, this issue is fixed in the version 1.4.3 of the YafaRay rendering plug-in.
Thanks for your patience.
