Turn lights on and off

Is there a way to get rid to the dark when using light? I'm using light to illuminate a screen but I need to lower it when the surrounding environment lightens up. Is there a way to do that?

    When the intensity is on 0, the whole screen is black. I don't want the black when the light needs to turn on.


    I presume your "flashlight" is a Spot light? When you want to see the spotlight in the dark room, set the flashlight intensity to 100%. Add another new light (this time Ambient) leave the intensity value at 0. Click on the Intensity stopwatch for both light's intensity values. When you want the main light to switch on and the flashlight go off - change the flashlight intensity value to 0 and the ambient light intensity value to 100%. This will create new keyframes. If you want the value to change suddenly follow my previous instructions for held keyframes.

    You can animate the intensity of a light. You can also add Ambient light to the scene. Sometimes you need to lower the intensity of a spot or point light and at the same time increase the intensity of the ambient light. It all depends on you you have set up your scene.

    I agree with Rick, add an ambient light of about 50% to your scene. You may need to experiment with intensity. Also, you can adjust the material options of each layer to determine how much ambient, diffuse, specular light it accepts. This can help you fine tine the lighting in your scene.
