fbx into Blender, it also shows only a single animation, so the problem doesn’t seem to lie with UE4. I simply can’t get it to export all actions into the. Instead, select the object and hit tab on its action in the NLA editor.I’ve spend the last several days unsuccessfully trying to export a rigged and animated mesh with all its animations for use in UE4. Also, don't switch what you're animating by swapping what action is active. So, to fix your issue, make sure the action in the action editor matches the selected object. It's now jumped to the active action track and appears in the Action Editor.

Just like entering and exiting edit mode, that allows us to edit the action. I'll hit X in the Action Editor to clear that out though, and instead hit tab on the CubeAction strip in the NLA Editor.

Now if we choose the SphereAction in the action editor, the SphereAction will jump into the cube's active action track. Now we can slide this strip around and do whatever we want with it as a whole - it's like the action is now in object mode instead of edit mode. This makes it a strip and you'll notice that the Action Editor is now empty because we are no longer editing that action. Now, with the CubeAction assigned to the cube, I'll use the push down button in the NLA editor. Check out what happens if I swap actions with the cube selected: Whatever you have open in the Action Editor will be the active action. It allows you to have multiple actions per object instead of just one active one. Now the Cube's active action is SphereAction, as we can see if we switch back to the Dope Sheet. Let's say I still have the Cube selected but in the Action Editor I switch to the SphereAction. I have the Cube selected in the 3D view, so I'm editing CubeAction because that's its active action. The Action Editor displays the active action for the active object. When you switch to the Action Editor though, you can only edit one action at a time. In the Dope Sheet you can see that the CubeAction is under the Cube object and the SphereAction is under the Sphere object. In this example I'll just animate a cube and a sphere.

If you have both open at the same time then it makes more sense. The secret to the NLA editor is the action editor.
