ok so i make the box 5000 by 5000 by 2000 convert to mesh and flip.
I want to make only the ground have a texture. But everytime i choose a bitmap near diffuse and pick a color it only shows that color.
Another thing is when i try and change the numbers in soft selection it doen't do anything at all. Can anyone help?

if you are using 3dsmax, in the material editor, click the cube (show map in viewport) that should make it visible
