Call of Duty 4: Building Stairs

This tutorial will show how to create Stairs Prefabs using terrain patches::

Result are as follow:

• Create a new map in Radiant, select the texture ch_concretewall02 and using Z 2D view create a brush of

X = 20
Y = 8
Z = 80

• Deselect the brush (Esc)
• Select the outside faces of the brush now using Ctrl+SHIFT+LEFT-CLICK and go to Patch>Faces to Terrain

• In the texture window look for the texture com_stain_01 and click on it
• Still with the new faces selected, press 'S' and hit 'Lmap' - This will adjust the texture to the size of the faces.
• Deselected all (Esc)

Now you should have this:

• Select all using 'I' and press SPACEBAR to Duplicate the brush+decals
• Place the duplicate brush+decals as shown below:

• Repeat as many time as necessary

• Now to adjust the side of the stairs place your self in the X 2D view and select one step at the time (one brush) + the 2 decals (each side) requiring to be adjusted

 Make sure to select both the brush face and the decal by right-clicking on the 3D windows and selecting both.

• Drag all to the level of the first step, when completed it should look like this:

• Now we need to adjust the decals are they are clearly streched, for this select all the decals (both sides of stairs) using Ctrl+SHIFT+LEFT-CLICK and make sure you arent selecting a brush face by right-clicking on 3D windows and making sure only WC/com_stain_01 is selected:

• When all decals are selected press 'S' and use the 'Lmap' tool to adjust the textures.

• Finally select all using 'I' go to File > Save Selected > Save under the name you want under /map_source/prefabs/
• Note that you could at this point add a row on the top terrain patch of the steps and move its vertices to make an uneven look.
