Landscape UV Coordinates question

Okay, so I’m using splatmaps to apply my materials to the landscape. I’ve used a UVLandscapeCoord node to set up tiling. The coordinates are based on the resolution of my splatmap and heightmap (4033 x 4033).

Well in my world machine to unreal engine workflow I will reduce the scale of my landscape in the X, Y and Z channels to get the scale correct. I have a certain conversion i use to match world machine units to Unreal Units.

Well the scale conversion seems to work great, except for the fact that my material resolution is too low (large grass blades from material). After scaling down my landscape actor do I need to also scale down the UV Coordinates to match?
