Material applied to SM_Floor 400*400 not respecting UVs

Hi there,

i have an issue , i want this glowy material applied to the default UE4 cube to be applied at least correctly to the upper face of the SM_Floor 400*400 mesh as it is with the cube face (i mean highlighting the edges the same way).

i have created parent material called “Glow_High” and make 2 instances of it “Cube_Glow” , and “Floor_Glow” applied to the Cube and Floor 400*400 respectively ,with adjustments made to the floor material parameters to fit the floor correctly but i can’t get it right … So i want the glow to highlight the edges on the floor the same way on the cube …How to do it …???

See pictures below …
Thanks for your support …
