Shadows – Toggles the shadows of the current light. Disable this to turn off shadows.
Shadow Bias – Moves the shadow toward or away from the shadow-casting object (or objects). Higher values move the shadow toward the object(s) while lower values move it away. If this value is too extreme, shadows can "leak" through places they shouldn't or "detach" from an object. Other effects from extreme values include moire patterns, out-of-place dark areas on surfaces, and shadows not appearing at all in the render.
Shadow Color – Controls the color of shadows for this light. Note that anything different from black is not physically correct.
Shadow Radius – Specifies the size of the light. A value of 0.0 makes the light a point light. Larger values produce soft (area) shadows.
