Assuming that the static mesh is either a plane or some other piece of geometry. Could you not just rotate the mesh so the opposite(front side) is viewed by the camera?
this looks simpler 
Hi everyone,
I was trying to use blueprints to achieve something that may look simple and I have an idea of how to do it. I was just wondering if there was a better or even easier way of doing this.
I have a static mesh that represents a card in a card game. The card has a material that is the back of the card. When I select the card I change the material with a material instance with a texture parameter. The parameter represents the front of the card.
Anyone has any suggestion of other ways how to do this?
thank you

It sounds very tricky )
Why dont you use simple two-sided mesh with 2 material indices?
