How to add a padding to a not fitting landscape texture

Hey guys,

I am importing BFH maps into unreal engine 4, but it seems that the colormap does not fully cover te heightmap.
Is there any way to add a padding, so the colormap fits well?

BTW Sorry if this is a stupid question, I am just noob :S

I found it!

In the LandscapeCoordinates change:

-> the Mapping Pan U
-> the Mapping Pan V
