Linking FBX imported object to its spotlights bluprints ? Noob inside...Need help...

Hi there !

I have a big problem encountered while my learning of the unreal engine.
I’ve starting with short animations , but now , I want to learn more , and step up with an another little project. Here , the link of many abjects with an other :

I’ve imported my Millenium Falcon mesh , and to make it more accurate , I’ve placed spotliths once maps edited.

All my spotlights are bluprints , to make me modify one , and as others are instances… You understand.

But… My Falcon must take off. And he must do it with its spotlights ^^'.
And that’s the problem.

I’ve just started a few days ago , this engine , and I’m a bit lost concerning many of parameters of the software.
But I wanted someone to explain me why I can’t animate the falcon and its lights when they all already attached…

It’s been hours I’m tryning to understand …

I’ve seen videos explaining how to parenting obects with each others… but there , it doesn’t work.

Could someone help me please ?

Thanx a lot !!

edit : My landing gear must be animated to , that’s why I’ve choosen the import of the FBX with prepared mesh inside it. And maybe it’s an error , since I can not animate the falcon as a unique object in the sequencer…

I need a kind of routine , a … good way of undertanding about how to animate composed objects…
