{SOLVED} Ceiling material in PBR shown with black not-rendered triangles

[Renerabbitt]

I've ran into this problem before and don't remember the solution. Working on this kitchen design and the cln'g mat'l is being such a nuisance. Id prefer presenting this particular kitchen in PBR as the levels of sheen really make this stand out in a way that I can't achieve in regular 3d view.

Rene, 

Try removing the 3/4" knotty oak from the roof surface layer and just use the white T&G from the ceiling finish. Nah that didn't work - still shows in another part of the kitchen and wrecks your eave structure.

Just tried your suggestion. Triangles still exist even if I remove all texture files from the cln'g mat'l. Maybe it has to do with insufficient lighting. I haven't dug in on this one yet but thought someone might save me the time if they had encountered something similar.

I just took a quick look and I think it has something to do with the exterior top plates, the wall finish is not covering them and it looks like there is a gap up there.

I almost sent you a PM before I posted this b/c I figured you would have the solution; Of course as soon as I read your response I thought "DOH!, he's right," but alas, I manually dragged the walls up and the problem still exists. I agree that joinery would be my first assumption for this sort of thing, but it reminds me of a poly face issue I've had before. 

I guess I will have to dig into this one myself when I can find the patience

Wow that is stubborn. I can get the large triangle to go away a couple different ways, lowering the roof and changing the walls from balloon through ceiling to stop at ceiling, but that little triangle over the sink area persists.

Rene,

 

I changed the room's ceiling finish to the 7/8" T& G, deleted the Ceiling finish in the roof dbx, and then checked use Room Ceiling Finish in the Roof Structure dbx - it seemed to work.

You're the man, thank you for the effort. This plan is such a mess, I was in such a rush, saved me!
