Animating Assets from Marketplace in Sequencer?

Hi, i am a newby and been searching the whole day for a good solution for this:

I am using some assets from “Vigilante”, like the F15, B2 Bomber, 688 Submarine, etc in a movie render, and i want to simply sequence some of the already integrated blueprints or at least the moving parts like landing gear, flaps, canopy and stuff.

Found out i can somehow link the sequencer with the blueprints and i was also able to set a fixed value, but i need something like a ramp from 0 to 100 to get a smooth animation effect.

I dont have a clue, this must be easier to do than i think i guess? maybe someone can please point me in the right direction!

btw. i dont have any problems animating characters and other world objects with selectable bones or animations integrated, but none of them used blueprints for landing gear retraction and stuff :frowning:

Thanks for any hints!
