A Beginner question

I’m probably not doing this right but I’m a beginner to Unreal and I wanted to make a simple model for a story I’m doing. I wanted to make a stack of TVs sitting on top of each other but I’m not sure what to do to make that happen.

Tips?

Make a single 3D model, the Tv.
Import the model into Unreal.
Make textures and material instances.
In level, duplicate the 3D model of the Tv and apply material instance with variations, making it look like different Tv models.

Dont forget about setting the different materials for the plastic and the actual screen of the tv when you are using your modeling program (blender, 3d max). Otherwise you will only we able to put 1 material into it
