How to Use Property Locker
Basics
- Select any properties across any layers
- Clickthe
Property Lockerbutton to lock or unlock
Behavior
- Locking: Adds an expression that hardcodes the current value
- Unlocking: Removes the expression and preserves the post-expression value
- Toggle: Each property toggles individually based on its current state
Existing Expressions
If a property already has an expression (not from Property Locker), you'll be prompted to:
- Overwrite: Replace the expression with the locked value
- Preserve: Skip that property and leave the expression intact
Tips
- Works on any animatable property: Position, Scale, effect controls, shape properties, paths, etc.
- Select multiple properties across multiple layers to lock/unlock in batch
