Slider to control mesh visibility

Hi everyone!
I hope you can help me with a problem setting a slider.

My slider controls the visibility of a mesh. For now, I’m able to make the 3d model start transparent and gradually become opaque.

:question: How can I reverse the process to start from opaque model and turn to transparent? :question:

I’m relatively new to Unreal. Any feedback is welcome!

I think (1-slidervalue) gives you what you’re expecting

Thanks so much! I tried with multiplications and set the value with different intervals, but finally with your suggestion I succeeded! Thank you
