3dsmax Problem when importing Lines

Hello Guys!

I am new with 3dsmax and UE4, so I made a simple model of a table, everything working fine, until I try to export to UE4. When I try to trow the materials in each part of my table some spots works and others doesn’t work. I realized just where I did a “Line” in 3ds max doesn’t work, but for example in a Box, plane or whatever, It works… Idk what to do… =/

Look the legs of the table, just take the Color (Very metallic, but not the wood texture) But on the plane it’s working easily
