Nems:

Thank's for the answer.

A simple textures on the terrain works ok, but in this
case we was using the fx_terraintex3 shader with
a RGB-map and 3 tiled textures. That's were the problem
occures. Running the terrain with a lite-c script works, but
using a wdl script does not.

What we are trying to do is getting a working A6 MDL version of the tutorial
How to create terrains using Terragen.

Kindly
