Skylight Not Transmitting Light

I have a tubular skylight, but it is not transmitting light through.  You can see that the tube goes all the way through, but it will not show any light when I render the scene.

There is no daylight portal options when I follow those directions.  Also I cannot find anything about discipline under the properties.  The sun is on, because it is coming through my other windows and it is already set to few clouds.

Is this like a Solar Tube? Have you tried putting a light source in it?

I was looking for something like that.  I am fairly new to some of those aspects to Revit.  So how would I go about adding that in there?  Can I add it in my project, or add it to that family?

  1. Which Revit version are u using? The settings might differ slightly fro the link provided and (for instance:) 2017.2
  2. How did u model it? Is there a mass still in obscuring the light?
  3. Did u assign the right material? and what kind of asset did u assign for it
  4. can u upload it for check

1. I have 2017.2

2. It was a model that I downloaded, and then had to add the tube to go through the ceiling.

3. I used a mirror material to reflect the light just like it should in reality.

I don't think Revit has the intelligence to direct light off of trajectory path that bounces off of angled mirrors.  I'd have to explore this. I'll take a look at the family later and report back other suggestions.

I was thinking that it would be no different than a reflection in a window.

It is a very narrow and long light tube.  It will takes a lot of bounces to get the sunlight down that one.  I am not too familiar with Revit rendering engine so I don't what control the number of light bounces except for the quality settings.

I would just place an artificial downlight inside the tube.

I tried to add a light source to it just now, and even moved the light source to where it should be at the very end of it, and I get abolutely no light from it.

Are you using "Interior: Sun and Artificial" Lighting scheme?

Yes

Either you're not rendering with artificial lights on or the light is not passing through the lens. If the later, you can test real quick by just deleting the lens/glass from family and reloading and re-rendering.

I do not understand why the light source that I added to the very bottom of it will not emit light.

Here is a test with a lightsource inside the tube near the bottom and random sh!tty settings.

What are your light source settings?  Those exposure settings will just change my picture.  I have everything else in my rendering the way I want it, but the client wanted sunlights and I need to show these, and if there is no light coming through there, I know that they will ask why its not.

you have to set rendering to use both sunlight and artificial lights. Where your artificial light source is located at; be it at the top or the bottom of the shaft, depends on where your camera is positioned. Is this an interior rendering or exterior?

The light source is created from the OOTB non-hosted Light Fixture family template and manually moved to location in project.

 

I do not ask you to change the exposure.  I did it merely to indicate putting a light there works.  You just need to control the light intensity and location to your liking.

 

I am running a test render with the artificial light OFF.  I will post it when I see something worthy.

 

okay here goes:
