Unusual light against ceiling line

Every time I render from Sketchup to Enscape I get a strip of light around the ceiling line, and there seems to be absolutely nothing I can do to get rid of it. Can anyone help tell me what it is, and how I might be able to remove it? I’ve attached an example.

Thanks, Zoe

@Ladyzaun I have the same problem.

A work around is to model extra geometry on the ouside to ‘block out’ the light and colour that geometry black.

@Ladyzaun , what @houseofmanuela said, and check out this article here too which goes into detail a bit more.

I always make my ceilings double, it automatically work for first story since you have a slab on top anyway, but for single story or first story (top floor) I make the ceiling with one plane, but then depending on the roof, if it’s flat roof, it works the same as with a slab, so no problem, if it’s a sloped roof a single plane for ceiling, and the roof itself over it, also fixes this issue. Otherwise, like what was said already, if you are just going to do a interior shot, no outside, then just block it off on the outside yes.
