Importing FBX to Unreal Engine with parent/child hierarchy

I have some object hierarchy that was created in Blender and exported as FBX:

modular part ← window frame ← handle

But when I’m trying to import it into Unreal Engine I see only the first level of hierarchy (only modular part and window and handle imporsts only as asset). I’ve checked if there is any problem with importing it into Unity and there is no issues with FBX file (I hope), 'cause it totally works in Unity.

So how can I import it into Unreal Engine?

I’ve managed to do that. I’ve tried to export it from Blender as GLB file and it’s easily done.

But don’t forget to apply Transforms in Blender file BEFORE you create parent/child relations, because it can cause attaching child’s origins to parent’s origins when you do that after you have parent/child hierarchy. And as well, make sure your face orientation is correct.

And make sure have chosen “Use T0 as Ref Pose” under the Transform options while importing it to a level in Unreal Engine.

IT’S REVOLUTIONAL!!! Wouldn’t expect that it works! If I’ll find more advantages of GLB files over FBX I’ll write that in the next reply.

Have you try File > Import into Level for your FBX?
