Material applying incorrectly on imported mesh

So, I made this cube primitive in Blender, and I unwrapped the UVs in the basic “T” pattern for cubes. I’ve got another material that creates a whitish-blue outline effect, and it works perfectly on UE4’s basic cube primitive. Visually, there is no telling which cube is which when no material is applied to both cubes.

However, when I apply this material onto my imported cube, the material is completely messed up. I applied another material that used a cobblestone texture, normals and all, and it worked perfectly, no seams or anything. Anyone know what I’m doing wrong? Is it just the material I’m using?

UE4’s cube primitive on the left, my imported cube on the right.

And the material if it provides any insight

the primitive cube has each of its sides spanning the entire 0-1 space of the uv’s, while yours is a T-shape.
seperate each side, overlay them perfectly and scale them until they fit the 0-1 space of the uv-map.

Ah, that works. Thanks!
