Elevation of terrain water (usually just below the elevation of the land)(However, some infos are necessary to be input or altered before the terrain water to show up.)

The instance series of 0x00005CC(0-?)

it seems to be related to terrain paint/covering ("terp"), and it may be the alpha strength for a particular terrain paint ("terp"), but whether it's an inversion or not is not sorted out? or is that dependent on the terrain_txtr file?

N???_Lot???!terrain_txtr has the terrain paint graphic info updated when a terrain paint is added or removed.

The instance 0x00005CEE appears related to terrain paint/covering ("terp"), and it may be the referenced numeric value for a particular terrain paint ("terp").

The "Lot Texture" 0x4B58975B had the terrain paint names added following the default ones.

Unknown EC44BDDC's 00006C7A and 0000C284 had some changes.

Although unknown 0x6C589723 has a string called "terp", no obvious change is observed in a testing.

N???_Lot???!terrainmaterial_txmt remained.
