Model's scale has no effect on media texture

I’m trying to get 360 video mapped to the inside of a cube and the camera inside. I have everything working correctly, except the scale of the video. No matter what scale I set the model to, it never changes when I hit play. It can be 1 - 10,000 and the result is the same.

Steps I have taken:

  1. Create a cube in Blender, reverse the normals, export as FBX.
  2. Import into UE.
  3. Import movie and make the media material the material for the cube.
  4. Change shading model of material to Unlit.
  5. Place player in center of cube.
  6. Preview.

After those steps, the scale of the fbx changing has no effect on the size or orientation of the video being played. Why is that?

Bumpity bump.
