Hi Everybody, have been reading Revit City for a while but only just got around to registering.

I'm having an issue when trying to render a night scene. I have a building modelled with a section of glass front and a combination of lights inside and some external lights.

 I am trying to render a night image of the scene so to do this I have adjusted the sun and shadow settings so that the time is approx 7pm and have changed the lighting scheme to Exterior sun and Artificial Lighting and have checked that the artificial lights are all ticked.

The above doesn't seem to be working at all, as far as I can make out there is no light emitting from any of the lights. I did a trial render with the time at midnight so the scene was a lot darker and there was a tiny amount of light coming from the lights, nothing like the effect I was after.

 Is there a setting im missing or how do I increase the lighting amount?

 Many Thanks for any help.

Simon

First Welcome to Revit World....

If you check there are a "tiny amount of light coming from the lights" pick in one light, go to the properties, edit/new and in the bottom you have the "wattage" increase that 10, 100, 1000 times until you have the effect you want...

BTW, after the render you have the "Exposure control" where you can "smooth" the image....

I Hope and I Wish to LEARN  more, and more, and more.... REVIT

Thanks!

 I actaully manged to achieve the right effect by in the render diag changing it to artificail lights only and then setting the backgroudn colour to a dark blue. HOwever it would be nice to do it still with a cloudy night sky so i'll give your suggestion a go.

Many Thanks
