Skeleton not attached after importing to ue

Hi, i Recently made a model in Autodesk Maya, rigged it and animated it. Some parts i parented to the skeleton.
After Importing the model to UE i can see the skeleton moving but the model stays still, like it’s not rigged. the parts that i parented to the skeleton move with it.
So what could be the cause of that? When i imported a similar model theskin was attached.

I ended up making a new model, changing the export settings, and it worked.
If you are having a similar problem, it is probably just the export settings.
