title: How to access a material instance variable from a blueprint object in Unreal Engine?
body: <p>I have a texture material that changes between 2 textures. This change can be controller by a variable. I've made a material instance from this material as well as a blueprint that has an object in it, to which this MI texture is applied to. I was hoping to update the materials variable parameters through the blueprints event tick but I am having difficulties figuring out how to access this parameter.</p>
  <p>Would anyone know what has to be done in blueprint to access parameters and change them?</p>
