Making a doorway prefab

This is the long tutorial as I will walk you thru all the steps of making a doorway prefab.

The first thing I do is make a simple box map.
Then I build a brush the same size as the doorway texture.
Put the texture on both sides and caulk on all others. The fast way to do this is first select the brush then caulk (its in the texture/common/caulk) then hold down ctrl and shift keys then left click on the face in the 3d window then left click on the doorway texture in your texture window. To select multiple face hold down the ctrl-shift- alt keys the left click on multiple faces. 

Hint don't move the brush, resize it by increasing the height and width until its the same size as the doorway texture.
I also use snap to grid at 32 for this stage...
Should look like this...


Next I start cutting it up into smaller brush's. Use the clip tool for this if you know how or do the following.
When I do this I make a copy of the first brush by first selecting it (left click in the 3d window) then hitting ctrl-c then ctrl-v to paste this will give you a copy of the first brush in the same space. Next I resize both brushes (remember don't move them by dragging, resize them)
Should look something like this. 

If your stuck here and can't figure out how I did this go to this page for a more detail example of how to cut up the door way.

Ok maybe not you will have to do some edge dragging, or clipping to get the angles on the inside trim pieces. 

Select that brush then hit the E key notice all the dots on the brush these are control points, lower your snap to grid to say 2, now left click and hold on the upper corner that you want to move, now drag it down.
Keep a eye on the 3d window zoom in if you have to stop moving the point when it looks right. Repeat with the other inside trim brush... Ok so now it looks like the above pic right...

Now you need to split the center brush in the door way into two equal sizes. You now the drill by now select it then ctrl-c then ctrl-v resize both so it looks like this..

Now the fun starts its time to turn these brushes into bevels (curves) also known by simple patch mesh's.
First select one of them, now go to curve then bevel.
Like this.

Next you will have to hit either the 
or  buttons to spin the bevel into position. Then resize the bevel in both the x view and the z view to the right size, again don't drag the bevel, resize it.

Now it should look like the pic below.

Now with the bevel still selected go to the curve menu and then matrix then invert or (ctrl+I). Then pick a texture from the texture window. For this tutorial I used gothic_door/xian_tourneyarch_inside2.
Now hit the Shift+S key to bring up patch properties window and then hit natural.

Now repeat these steps for the other half....
Should look like this


Now we need to caps on these bevels.
First select one of the bevels then go to curves then cap, then inverted bevel a little window will pop up like this.

select the inverted bevel.

Now you have caps for the bevel but wait there's more.
While the cap's and main bevel are still selected. Right click on them in the x or y view a little window will pop up now hit the ungroup button like this.

Note (You may want to use the tab key to cycle the meshes in the group instead of ungrouping I just like them ungrouped)

Now unselect the bevel and cap. (esc key)
Then reselect the caps (left mouse button while holding the shift key.) Or do one at a time.
Next select the doorway texture.
Looks ugly don't it don't sweet it we will fix that.
With one of the caps selected that has the doorway texture applied to hit press the Shift+S key then natural then, ok..
Still ugly huh..
Now hold down ctrl and shift and press the n key keep pressing the n key until it looks right...
Repeat this for all caps....

Now it looks like we are almost there right well not quite.
The way we built this will cause sparkle's on the edge of the bevel's. This is not good, so we are going to fix that and also merge some brush's..

Ok lets start.
Our doorway looks like this.


The brush's next to the caps need to be the same size as the bevels.
So lets change them until they look like this.

Notice I used the edge tool on the side and top brush to make the beveled corner...

Now select the bottom trim and outside joining brush.
Like this.

Now hit the merge brush button.  or ctrl-M 
Now that was easy huh, do the other side too.

All we have left  to do now is texture the inside trim.

And then select all the brush's and bevels and cap's.
And then hit the edit button, then save selection as prefab.

The next time you need this doorway in your map all you have to do is load prefab and move it into position....
