I was looking for a “Save Thumbnail Angle” in the static mesh viewer. Does such a thing exists ? It was a cool little thing in UDK. You would set your camera position in the asset viewer and take a snapshot which would show up as your preview in the little squares in the Content Browser.
In the lower right corner of the Content Browser, click View Options and turn on Thumbnail Edit mode. This’ll let you change the angle of static meshes right there in the browser. When you find an angle you like, just click Done Editing.
