Anyone else have ideas on this?

I seem to be missing something obvious in what I want to do.  I want a scene to be dark until a light is turned on.

So, if I have this stage built, I want zero light cast on it until I turn a light on for example (like a spot light on stage).

Obviously, darkening the stage image itself isn't the answer.

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.
