Why my material looks diferent on a similar diferent object?

I’m new to unreal engine 4!
I’m having some problems with the materials! I used the same material on both of the objects but the material looks different on the second one. The only difference between them is,in the second one there’s a rectangle hole.

How did you create those meshes?

It looks like you inset the face and it messed up your UV unwrap. Re-unwrap it and it should fix the issue.

It work’s!
Thanks!
