How can i change my floor , wall , furniture ...etc texture or color during play mode

Helllllo Everybody ,

Am trying to get Unreal engine into the Architectural Market with a unique way and I believe if we can change the textures of the scene with a very dramatic way using buttons or going through a slide will really help improve the presentation , am sure this is gonna be done by a Blueprint codes but am i dont know how to use the blueprint , so how can we do it guys so we can all get benefit also form the technique in our arch viz presentation .

Thanks

I suggest you check Epic’s official blueprint tutorials to get started because it can get quite complex very Fast!!!
