Use a model from blender in UE5

I am still learning to do some things but i do have a blend file in blender. It is a AR-15 i believe and im trying to export it out as a fbx file and import it into ue5 to use it as a weapon. But i am needing a static mesh in ue5 and i dont know how to get it from the blend file. or how to make it.

Another thing im having issues with is my model in blender is in muliple parts. multiple multiple layers. when i export the model and put it into ue5 it shows up in UE5 as multiple different parts. Multiple different things like it is shown in blender.

How do i export a model from blender thats in multiple parts and export it as 1 single 3D object and not multiple small ones?

You need to watch some ue basic tutorials. Collision mesh or Physical Asset is something which will be a separate model which can be exported and imported. While “static mesh” are basic settings of the mesh itself inside unreal. It doesnt have any connection to mesh inside blender/other dcc.
