I believe you’re asking how to apply the rotation/scale on the object when you export out of a 3d program? These were created in Blender, so in there you would need to apply the rotation and the scale by using CTRL+A which will then pull up a pop up menu allowing you to apply the rotation/scale/location as you’d like.
Regarding using an empty game object, I would almost always recommend adding that anyways. I very rarely like to add scripts and components directly to mesh objects. Reason being is that you may want to swap out that mesh object at any time, and/or disable it so it’s not visible in game. If you have a lot of components on that object it makes it more difficult to customize in that way.
Not only that, but in any situation where you want to control the rotation/position of an object in a different manner than the actual mesh orientation it’s much easier to use an empty to control that. If there’s something else you were asking about let me know, thanks.
