Hi 3 questions really.

1. How do i make bomb craetors in the ground

2. How do i apply a different texture on the outside to the inside texture

3. Do i have to use a terrain to change a little height in a map or is it possible to do it with brushes such as a little slope going upwards

Well for the craters, and terrain use LOD terrain.
and the different textures, if you want to apply a texture to a wall, select the wall by pressing shift+ctrl
