Apply MotionField

Select one or more layers in your composition

Choose a MotionField mode from the panel

MotionField will automatically:
Create the MF_Master layer if it does not exist
Apply expressions to the selected layers

Your layers will now respond based on their distance from the controller

Move the MF_Master layer and adjust settings to control the animation in real time

Make sure a composition is active before applying

If nothing happens, check that your layers are selected

For Color and Custom modes, select a property before applying
