Tech/LxEngine/Samples/LxMorrowind/LAND records

A LAND record starts with:


 * INTV
 * int gridX
 * int gridY

when loading an exterior cell, the cell's grid x/y can be used to load up the surrounding LAND landscape data.

Then follows:
 * DATA, 6 bytes
 * VNML, 12675 bytes (vertex normals)
 * VHGT, 4232 bytes (vertex heights)
 * WNAM, 81 bytes (???)
 * VCLR, 12675 bytes (vertex colors)
 * VTEX, 512 bytes (vertex uv coordinates?)

Landscape cells are supposedly 64x64 quads. 64x64 = 4096.
 * VNML is 65x65x3 = 12675 in size. THe normals are likely stored as signed bytes that are then normalized by dividing by 128.
 * VHGT is 4323 bytes. This could be 65x65 + 7???
 * WNAM...what's WNAM?
 * VCLR is presumably the same as vertex normals, each byte is 0-255 unsigned byte color value
 * VTEX is 8 x 8 x 4 x 2 = 512 bytes. Possibly 2 floats on an 8x8 grid that is interpolated across the grid?  Or is it 16 x 16 with a byte per uv?
