this is the most i can provide you with( commented code for building a terrain)
There's nothing in the help file
_______WORLD_BUILD_________:
hgtmapsize=256
terrscale=100
terrheightscale=100
create_terrain1:
rem this is the terrain texture (ground landscape)
load image "terrtexture2.bmp",1,0
rem this is the detail texture (tiled on top of
rem the land texture according to the tiling command)
load image "detail.tga",2
rem make the object terrain
make object terrain 1
rem profile it according to the heightmap gray scale
set terrain heightmap 1, "heightmap256.bmp"
rem set the scale (size) of the terrain - (xlength,height,zlength)
rem it equals the heightmap size x the scale factor
rem in this case 256 x 100 = 25600 DBP units
set terrain scale 1,terrscale,terrheightscale,terrscale
rem split value (number of limbs for culling)
set terrain split 1,8
rem detail map tiling
set terrain tiling 1,4
rem light - xdir, ydir, zdir, red, green, blue, intensity
set terrain light 1,0.6,0.6,0.6,1.0,1.0,0.9,0.9
rem texture the terrain with base (1) and detail (2) texture
set terrain texture 1, 1, 2
rem finally build the terrain
build terrain 1
return
