How do i transition smoothly between variants in the Variant Manager?

Hi, thanks for taking a crack at this for me, really appreciate it.

I am building a car configurator using the variant manager in 4.25, i pretty much have everything i need down, except i want to be able to smoothly open a door by transitioning between two variants, one with the door open and one with the door closed, when i press a button in the UI.

What do i need to add to my blueprint code to make this happen. Any help would do. Thanks
