If an object's Cast Shadows is set to Off, what happens to lighting from that object?

• A. The object still casts shadows
• B. The object will be invisible
• C. Lighting becomes completely disabled
• D. Light passes through and does not cast shadows

Answer: (D)

When Cast Shadows is Off, the object stops contributing to shadow casting in the scene. It will still be lit by lights and remain visible, but it won’t create a shadow on other objects. In practical terms, light can illuminate surfaces as usual, yet there’s no shadow projection coming from that object onto others. This is often used to improve performance, since the shadow calculation for that object is skipped. Note that the object can still receive shadows from other objects if that option is enabled, so its appearance under lighting remains normal without producing its own shadows.
