Where are the settings in the Heightmap Editor for displaying which quads I'm looking at? I'm having problems generating the LOD meshes, as it only generates the quads centered around 0,0 in the Heightmap editor (the ones that are visible), however the Heightmap for my mod extends further than this, so how am I to get LOD landscape meshes for the quads outside of the visible area? Are there settings for this somewhere in the CS?

Help asap would be appreciated (hope to get this Height Map up on TESNexus for playtesting within the next few hours).
Cheers,
