Masked
Textures
Ok before we
start I am presuming you know the basic aspects of using Worldcraft if you don't,
Then take a look at Blinks Basic Tutorials. :]
Masked Textures
can be highly useful in many aspects for making ladders, grates and so forth
In this Tutorial we will learn how to make Masked Textures our best friend :P
Ok, lets start
off by making a simple room with the Block tool (Shift+B) and place an
info_player_start inside the room

Ok now make a
block on the left side of the room that is half the width and half the height of
our room

Now we are going
to place a ladder on the front of the brush we just created so you can scale up
the block to the top. Ok so crate a new brush with a Width of 32 and a height
160 the height of your brush may dither thou if 160 is to short just make it
longer :]
(NOTE:
Worldcraft displays the brush Width and Height in the status bar located at the
bottom of the screen)

Ok now this is the part where
the masked texture comes in. Bring up your Texture browser (Shift+A) and click
Browse and type { into the Filter. A load of pictures should appear, all with
blue backgrounds. These are Masked Textures. Now in the filter type in {ladder
and pick a ladder texture that you like by double clicking it. Now right click
on the ladder - the texture you just selected should appear on it if you make a
mistake just press Ctrl+Z to Undo it. :]


In game the blue turns
transparent allowing you to create this ladder and such. But in order for the
blue background to be transparent we have to change the brush we are using as
our ladder into an Entity
To do this press Ctrl+T to
bring up the Entity selection box in the filter type in func_wall

Now for the
Render Mode set it to 'Solid
For the FX Amount set it to 255. FX Amount determines how much blue appears in
the image while in game. Obviously we want it set to Max (255) while 1 would
give the texture a totally blue background (we don't want that :]) ok now close
the Entity box
Now so select
the ladder and press Ctrl+C to copy it then deselect it (just click any where on
the grid) now press Ctrl+V to paste the brush. Now align it exactly the same as
the ladder right in front of it

Keep the copied
brush selected and bring up the Entity Box again (CTrl+T) you will get a pop up
box asking whether you'd like to keep the old entity, press no - and type in the
Filter func_ladder and close the box func_ladder is basically the part that
actually allows you to climb the ladder not the Texture.

Ok bring up the
texture browser again and select {fence2 now select the Block tool and create 2
brushes on both sides of the ladder on the upper level and make it func_wall and
give it the exact same options as the ladder

And here is the
result

If you spend a
little time messing about you can use the masked textures to great effect
