I can't seam to create a terrain with my own textures.
I started by creating a folder and added the textures I intend to use for my terrain. I created the terrain and when I import it, only the Grass Texture is seen and the rest is White.

I have the following programs to create a terrain and I have tried them all.

Caligari Truespace 7.6
Caligari Gamespace 1.6
3D world Studio
Nems Terrain Generater

PS. Is there any other terrain tools that are compatible with A6 or A7 ?

I use earth sculptor, its the best one i have come across yet i just export it as a height map. Another good program is T.ED but the textures that get exported from T.ED are not in as good quality as earth sculptor.

I would recommend getting the free version of earth sculptor.
