Interior lights not rendering

[jsteinhauer]

Hi All,

I have a residential project I am trying to render interior camera shots. My artifical lights are not rendering for some reason. They are grouped and on, but my rendering draft rendering is black. Is there some setting that I'm missing? I used the OOTB recessed can light fixtures. I see the cone of the light source. I'm stumped.

Thanks,

Jeff S.

Are your recessed lights hosted by a ceiling with a floor above?

If so, the [solid] floor geometry may be blocking the light source. Go to Visibility Graphics settings and turn off the floor category. Or, if a [lower] floor is visible in the view, select the [upper] floor in another view (e.g., section), while still selected, go back to your render view, right-click and select Hide In View.

If that was the problem, your lights should now "cast" their light.

When the rendering is finished adjust the exposure setting to brighter and see what you see. If its still black then there is something wrong. But the exposure settings are wrong by default.

...are wrong by default.

Hey Scott,
You've been talking to my significant other, haven't you!!!!?????
LOL
Have a great new year!!!

Now...back to your topic....What Scott said and, check the material for your lens and/or reflector. Sometimes these need to be set to glow too so that they look like they are on.

Best of luck

Hello Graham,

The light flxtures are hosted by the ceiling, which is 5/8" thick GWB. The floor structure above is set to 100% transparent. I thought setting the floor the floor structure to transparent would let the light of the recessed cans shine through. I will try a rendering without the floor structure on.

Thank you for your assistance.

Hey Scott,

What do you meen the exposure setting are wrong? What should the settings be? Or, does that vary to much.

Thanks,
Jeff S.

The problem with those can lights is that they cut the ceiling they are hosted in, but will not cut other geometry (such as the floor) that is just above the ceiling. The light source is then "buried" in the floor above and will not show unless you turn the floor off in that view, or use voids to cut out the floor where the can lights are.

Can you join geometry of a floor and ceiling so that the light cuts both? If you have a floor then you really don't need a ceiling, just make the drywall the bottom layer of the floor. Would that work, or are these lights only designed to cut a ceiling and not a floor? I rarely ever use ceilings in residential since 99% of the time it is the same as the underside of the floor.

The OOTB can lights are ceiling hosted and therefore will only cut a ceiling. Join geometry wont help in this case. If these lights were floor-hosted, they would work for you, as long as they were modeled to host to the bottom of a floor instead of the top.

Sounds like the lights should have been built as face based instead. Then they could cut floors or ceilings, but in my case not both. I thought that turning the floor structure to transparent would take care of this for me, but I guess thats not the case.

I'll run a rendering over Monday night with the floor turned off.

Thank you all for your assistance,

Hey Scott,

I just re-asking the question about the exposure settings. How are they wrong by default & what should the settings be approximately.

Thank you,

Finally finished rendering

Hey there,
Great start!
A couple of comments however....
I would add a hood or hood/microwave with cabinets above the range. There is a nice one on Revit City, with a microwave.
I would place some items on the counters and some dining room furniture in the room beyond so that it looks a bit more "lived in" rather than a vacant new home.
Lastly, I would add a nice ceramic tile or stainless steel wall covering behind the cook top which will help with the visual and the cleaning for your homeowner.

Just some ideas.
Great job
Steve

In my experience the Exposure setting is set by default to 14 which is very dark(good for exterior sun mid day renderings). When you move inside or do exterior night shots you need it down anywhere between 8-12 depending on the look you are after.

Note you can adjust it after the rendering so, just run the rendering and don't worry if its almost black. Once its done, adjust the settings and see what you like.

Nice rendering!. I would consider adding a sink as well. :-)

[jsteinhauer]

All components have to be modeled to their specifications. This is the kitchen for my parents new home (currently under construction). All of the appliances are from the Sub-Zero/Wolf companies. None of them are in Revit yet, so guess what I got to model over Christmas. I didn't get a chance to model the Pro-Hood. The wall above the back splash to the underside of the wall cabinets is going to be 3-Form, with a plate of stainless behind the range top. The kitchen sink is not visible in this camera shot. Also not shown is the Pro-48 Sub-Zero. I didn't want to add to much misc model information to the model, because I'm still using it for construction documents. I need to correct the site work and run some exterior renderings as well.

I posted one of the cabinet families at the following link: forums.augi.com/showthread.php?t=112583

Thank you for your comments & assistance.
