What happens when you click the lightbulb icon next to a modifier?

• A. It locks the modifier to the object
• B. It toggles the on/off state of the modifier
• C. It duplicates the modifier
• D. It removes the modifier

Answer: (B)

The lightbulb icon toggles the modifier on or off in the modifier stack. When it’s on, the modifier’s effect is applied to the object; when you click it off, the modifier is bypassed and doesn’t affect the geometry, but it stays in the stack so you can re-enable it later without losing its settings. This is how you test different edits non-destructively. It isn’t about locking, duplicating, or removing the modifier—the icon merely controls whether the modifier is active.
