Simply reverse the animation on the Start property to go from 100% to 0%.
thank u brother for your answer
i am know expand the text in the timeline .. animation..range selector
and convert the value from 100% to 0%
but nothing happened
can u explain more please
my problem after the change value from 100% to 0%
Text be apparent at the beginning
Disappears in the final scene
But it must be contrary
Try setting the End parameter to 0%. You always need to invert both values to invert the direction of an animator.
