How to Use Property Locker

Basics

  1. Select any properties across any layers
  2. Clickthe  Property Locker button 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
Liquid error: Nil location provided. Can't build URI.
