Now press “Shift+A”, go to “Mesh”, and select “Plane.”

Press “TAB” button to go to the Edit mode. Then press “S” and drag the mouse away to increase the area of the selected Plane.

In the Edit mode, press “W” and click “Subdivide” to subdivide the plane. Do this four to six times (as you like).

Now, press “A” to deselect all the vertices. Press the number “7” (on numpad) to see the place from top perspective. Select some vertices which are nearer to each other. Vertices are the points of intersection of lines. Their selection helps in developing the mountain peaks. Vertices can be selected by Right Click on a vertex of choice and holding the Shift button and Right Click on another vertex.

In the Edit mode, press “O” on keyboard for Proportional Editing Tool, and select Smooth falloff found in the options below (in the line of Edit Mode).

Now press, the number “1” (on numpad). Now drag the Arrow Widget (blue arrow) to move the vertices upward along z-axis. You can also move the mountain along x-axis or y-axis using green arrow or red arrow.

Press “A” to select all the vertices (selected vertices appear colored, i.e. orange colored), and press “Ctrl+T” to triangulate the mesh.

Press “A” again to deselect the mesh, and select Random Falloff mode found in the options below (in the line of Edit Mode).

Select some of the peak points and move them upwards. You can use the numbers in the keyboard to change the view and see different peaks. So, number 1 is for Front view, number 7 is for Top view, number 3 is for Right side view, and you can experiment with other numbers.

Now select all the vertices again by pressing the button “A” on keyboard. Now press “W” (after selecting all the vertices, i.e. highlighting them) to show the Specials menu. Select “Shade Flat” for giving a flat look to it and then press “TAB” to move out of the edit mode. You will see the flat mode. Save this file by pressing “Ctrl+S”.

While the Plane with Mountain is selected, click the “Materials” button (a small circle) in the “Properties” window on the right, and press the “New” button. Name the new material as, for example, name it “Green” and set the “Diffuse” color to dark green. Decrease the Specular Intensity (below Diffuse) to 0.0 that causes the material to become non-shiny.

Press “TAB” to go to the Edit mode, and press “Z” button on keyboard for Wireframe mode. Press “1” for Front view. Press “Ctrl+TAB”, and click Face in the Mesh Select Mode menu. Deselect the plane. Now press the button “B” on the keyboard and drag the mouse to choose the area of the mountain above the ground. Some missing area could be selected by pressing the “Shift” button on keyboard and Right Click on them. Selected points will be highlighted.

Now press the “+” button in the Materials menu to add a new material slot. Now press “+ New” button. This gives a new material “Material.001”. Double click on it and name it as, for example, “Brown” and set the “Diffuse” color to dark brown. Decrease the Specular Intensity (below Diffuse) to 0.0 that causes the material to become non-shiny. Now click “Assign” to assign the new properties to the selected region. Save this file by pressing “Ctrl+S”.

Now click the “TAB” button and press “Z” button on keyboard. You will see the brown color of mountain.

Now the “TAB” button again, press “Z” button, press “Ctrl+TAB”, click Face in the Mesh Select Mode menu. Now press the button “B” on the keyboard and drag the mouse to choose some topmost area of the mountain. Now press the “+” button in the Materials menu to add a new material slot. Now press “+ New” button. This gives a new material “Material.001”. Double click on it and name it as, for example, “White” and set the “Diffuse” color to white color. Decrease the Specular Intensity (below Diffuse) to 0.0 that causes the material to become non-shiny. Now click “Assign” to assign the new properties to the selected region. Save this file by pressing “Ctrl+S”. Now click the “TAB” button and press “Z” button on keyboard. You will see the white color on top of the mountain giving the effect of snow.

Now press F12 to render, then press F3 to save the file as an image.
