Hi

I'm not sure exactly what you mean. If the material is selected in the Mat Lab, and you can see it in the little preview screen in there, when you click the check sign it should go on to your terrain. The only way I can think of that it would appear that it hasn't is if you have selected 'smooth shaded' for your viewport models (found in the drop-down list you get if you click the little wireframe cube on the right hand side of the main screen). Make sure only your main render button is clicked to render, not any of the other four, two either side, buttons (which will appear red/blue if you have). Whatever the shape of the terrain is, that won't change no matter what texture you apply to it, unless you scale/transform it of course. Does that help?
