Hi Eric

if you use spot lights, then make sure the spotlight is directed at the surface, if you only check it in one view it can just look like it is directed correctly. Take a look at the scene from the top view or left/right view too.

Make sure the light intensity is set high enough if you have the falloff type on the light to "Inverse Square"

And see if you by accident have made the light color black. This will never emit any light no matter how high you crank up the intensity. This exact problem did catch me a few years back where i just couldnt understand why the lights never would render... untill i saw i had by accident set up the default lightcolor to black  :-D

I think my problem gets back to Walter Soyka's original response down below about accepting lights off and on.

It would seem if I set my surface layer (the stage in this case) to accept lights, place a light over it, I should have an illuminated area of the stage where that light is.  I'm not getting that however and it just remains dark.

Appreciate the help.

Eric

Hey Eric,

A link to a good visual reference would help BUT off the top of my head... Trapcode Lux?

Hello,

I started this thread a week two ago and have a follow up that pertinent.  I have this setup that includes like a large stage with a singer on it.  I have a bunch of spot lights focused around like a disco thing.  The look I want to create is to have the stage dark and when the spotlight changes position, it lights up the stage in the area it is directed.

Any ideas on how best to set this up?  I mean, I'd like the stage to be completely dark except where the light is focused.

Thanks ahead.

Eric

When you set accept lights to off, you are telling the layer to disregard the lighting in the scene. It will not be shaded at all, becoming neither lighter nor darker in response to lights.

If you have a light in the scene, accept lights is on, and the layer is dark, then it is accepting lights, but no light is actually hitting the layer. Since it's not being illuminated, it is dark. You may need to reposition your light, or add additional lights to the scene.

You can use an ambient light in the scene to raise the overall lighting level.
