UV-Remap Material Node failing on BSP?

If I use that node to set uv for a range it works if I apply the material to a mesh (example a cube mesh see attached images). But on a BSP it behaves as if it were tiled not cropped (see background in image). Is this a known issue? is there a work-around for it?

btw: the image is only an example, I know that it looks better on the bsp because the texture 4 corners are visible, this was just a test, my original intention of using uvremap is to reduce the border of texture (in this case the gap between tiles). Summary in the image bsp wrong, cub mesh right.
