Texture appears broken in Hammer but normal in-game (pics included)

[dabmasterars]

After compiling and launching the map, texture appears normal without any glitches, yet Hammer can't load it correctly. What's the problem?
I use the latest version of Hammer++ with the Ultimate Mapping Resourse Pack and TeamSpen's Hammer Addons.

    $basetexture "metal/stainless001"
    $surfaceprop "metal"
