Understanding light settingsUse the guidelines below to adjust light options. All the options, except Casts Shadows, can be animated. Note: For a layer to show a shadow, you must turn on the Accepts Shadows layer material option. See Understanding 3D layer material options for more information. Light Type Parallel light rays emanate directional, unconstrained light from an infinitely distant source. A Spot light emits light from a source that is constrained by a cone, like the spotlight used in stage productions. A Point light emits unconstrained omnidirectional light, like the rays emitted from a bare light bulb. Ambient light has no source but rather contributes to the overall brightness of a scene and casts no shadows. Intensity Sets the brightness of the light. Negative values create nonlight. Nonlight subtracts color from a layer. For example, if a layer is already lit, then creating a directional light also pointing at that layer and employing negative values to this new light creates an area of negative light, or a dark area, on the layer. Cone Angle Sets the width of the Spot light by adjusting the angle of the cone surrounding the source. This option is active only if Spot is the Light Type. Cone Feather Adjusts the edge softness of the Spot light. This option is active only if Spot is the Light Type. Color Sets the color of the light. Casts Shadows Indicates whether the light source causes a layer to cast a shadow. Shadow Darkness Sets the darkness level of the shadow. This option is active only if Casts Shadows is checked. Shadow Diffusion Sets the softness of a shadow based on its apparent distance from the shadowing layer. Larger values create softer shadows. This option is active only if Casts Shadows is checked. |
