Hi.
I have a problem that I am hoping to get some feedback on Re: soffits. I believe to be a X11 issue.  In my plan, i created open rafters first on attic level with no finished ceiling, the soffits would "glow" with emission. I am a part of Chief Tutor.com so I sent .plan to him to get feedback.  He took the file, put the soffit rafters on the first level and it fixed the problem on his computer.  However, when i did what he instructed on my own software, the soffits would still glow in physically based render with "improve lighting quality" checked, and they are downright black when the improve lighting is not checked.  He informed me it was  likely an X11 issue because he was able to resolve in the newest version.  Is there a work around I can do for this?   I am contracted out through a small construction company and they may not be upgrading to new version; So a work around would be ideal.  Thank you.  See attached files for images of problem.

Are they penetrating the ceiling/roof structure?  If so that could be the issue.

2 Suggestions 

 

Try for a descriptive title -- something like PBR Lighting Interior Exposed Rafters

 

and attach the plan file.

Do you actually have roof planes built on the model? the glow is usually because there is no floor or roof Structure above.

 

The Black is usually caused in PBR, as the PBR "Lighting Engine" thinks the Surfaces are in another Room ( or outside) and don't need to be Lit.

 

And I'd suggest you check your Digital Locker as X12 is Free for those with current SSA.

@rgardner  Thank you for the help! I dont believe they are penetrating the roof structure.  How do i efficiently check to this?  Cross section?  There is a roof structure although its pretty wonky currently.  I am not the best at designing roof lines.

@Kbird1 Hi! Thank you for your help/feedback.  Yes the model has roof planes, and most definitely a floor.  The roof is a bit wonky, as I am not stealthy at designing roofs quite yet.  I did send the .plan file to chief tutor and he said the all problems resolved in X12.

Yes do a cross section to see if the top of them are penetrating the ceiling plane.

Post the Plan when you have issues, otherwise it is just a game of 20 Questions......:) ........ way toooooo many things and settings involved.

Drop the soffits that you used to make sloped beams by 3/4".

Delete the soffit along the window wall.

Copy and paste one of the sloped beams. Move it against the fridge wall, resize it to the depth of the soffit you deleted then drag it along the window wall.

That will fix all but the soffit over the fridge. I'm not sure about that one but the first issue is the roof planes above have a hole in them and don't meet properly. Fix that and then work on that other soffit. Might need to make it from a psolid to get what you want but that won't work with the roof and hole in the  wall behind it.

      Hello, is there a way to display the ceiling elevation (height) on plan view, as we typically show them on architectural drawings?

      Hello,
      I have a soffit that just wants to be angled. I auto created the roofs and this happened. So I deleted that part and made my own - same thing. So I mirrored the rear roof at 45 into place - same thing. I have included the plan - anyone know why this is happening or how to fix it?

      Hello, Is it possible to create a ceiling assembly schedule in CA? I could not find one, nor an option to assign to a custom schedule. Any tips?

      can anyone explain how and help me enclose between this new gable roof and ceiling. Also looking toward house thru gable closing in with Hardi-siding. The old roof is showing thru and something else when I do a rendering (see attached). Need to look good for a client in 3 D. They are adding a roof over existing 10' x 20' patio. 
       
      thank you if you can help.

      I am having a difficult time with the framing of the rafters; in regards to birds mouth specifically. I am looking for assistance as I have tried many different options in aligning them to the beams. Please help me! I'd greatly appreciate it!
       
      Ps, I only began to notice the difference, when I changed depth of hip rafters to 3.5".
