The heightmap must be:
a greyscale Bitmap.
2^ power size(2x2,4x4,8x8,16x16,32x32,64x64,128x128,256x256,512x512... pixel per pixel).
The code for terrain creation is:
MAKE OBJECT TERRAIN 1 ` create the terrain object
SET TERRAIN HEIGHTMAP 1,"heightmap.bmp" ` set the heightmap
SET TERRAIN SCALE 1, 300, 8.6, 300 ` set the scale
SET TERRAIN SPLIT 1, 16 ` split value by 16 * 16
SET TERRAIN TILING 1, 1 ` detail map tiling
rem SET TERRAIN LIGHT 1, 1, -0.25, 0, 1, 1, 0.78, 0.5 ` light - xdir, ydir, zdir, red, green, blue, intensity
SET TERRAIN LIGHT 1, 1, -1, -1, 1, 1, 1, 0.7
SET TERRAIN TEXTURE 1, 1, 2 ` base and detail texture (previously loaded)
BUILD TERRAIN 1 ` finally build the terrain
If it is still not working can you upload the heightmap?
