Higher resolution terrain in Resistance

[Tier]

 One of the WrpEdit tutorials mentioned that it was possible to change the 50m terrain default in Resistance. Does this mean there is a way to use 30m DEM without resampling to 50m? Doing a little experimenting, I put a converted 30m terrain map into Wrpedit. Even with the import settings for height and width at 427(50m=256x256,30m=427x427), part of the map on the right side is missing.Microdem says the map is 427x427 and so does Wibur.
   Has anyone made a map in Resistance using higher resolution than 50m DEMs?

I dont think its possible yet as the tool for making the terrain is Pre-Resistance....
