I've been googling and looking through the discussion forums and I just can't figure out why my interior rendering scenes just show up black. I have opened up projects from previous releases that I was able to get interior scenes to render correctly and they render fine in 2013. I've imported the modified fixtures to the current projects file and they still don't do anything. The scene I'm talking about has a ceiling modeled on the underside of a floor. I've read this may be an issue, but my light fixtures light source is to be 1/4" above the plane of the ceiling. In my case, it's a 5/8" layer of drywall. I just can't figure this out.
Solved! Go to Solution.
Solved! by thaner9. See the answer in context.
Now serving a big plate of "yes, you're still just learning"...
Even though the image on the screen suggested my camera was not inside a wall, when I looked at it in plan form, it was. I moved it forward a bit, out of the wall, and now things work.
Notes for future forum'ers...
It still requires (at least when placed under a floor element) that the Light Source Elevation remain within the thickness of the ceiling element. I rendered with it outside of my 5/8" material (back to the original 3" above bottom plane) and it did not render. So, light fixtures won't render "inside" a floor.
If you want the fixture itself to have a "glow", you need to edit the fixture's "Light Source Definition" to have it's "Light Distribution" to be a spherical instead of spot. I've attached an image that illustrates this.
Thanks for everyone's help...
I would throw in a studio light to see if it is the light fixtures or not - it is jut an orb of light - no fixture. You can specify the offset from the floor to get the height you want.
On the rendering dialog box - what do you have the lighting set to? see attached image...
I've tried Interior and Exterior with Sun only, sun and artificial...etc. Doesn't seem to change anything. I'm just rendering in Draft mode to save time, not sure that matters. I've also adjusted the exposure to no avail.
I've edited the fixture to move the Light Source Elevation to be inside the depth of my Ceiling, but that doesn't seem to help.
I've also turned off the floor 'layer' and that hasn't helped...
WOW I am really at a loss - not sure what to say... hopefully an autodesk employee will take a look at this one...
No problem. Thanks for trying.
I'm tempted to start up a "dummy" project with Revit's Out-of-the-Box template and insert lights and see if it works there. Seems I always run into this problem when the upgrade happens.
Would not hurt to try...
Hope you get it to work.. when you do post what you did - if you don't mind.
I changed to 150W and still nothing. I created a "dummy" file and just made a 40'x40' box with a floor and a flat roof and then added a ceiling and some fixtures and everything works fine there.
