PART 5 -
CLIPPING
The main point I will be
covering in this tutorial will be how to do 2 point clipping
but I will also be covering a lighting technique that you
might well be wondering about...
CLIPPING?
You may have been wondering how
it is possible to make 'odd' shaped brushes. You know
the sort... Wedges... Curve effects...
That sort of thing...
Well now I will try to explain how to do this, because it's
really very simple. What you have to do first is make a
brush bigger than the shape you want, because clipping is
almost like planing a piece of wood. Imagine you have a
block of wood and you want to turn it into a wedge
shape. You angle the plane across the piece of wood and
remove the wood you don't need to leave the shape you
want. This is essentially what clipping is.
You start off with a normal
block shaped brush, and remove the parts of the brush that you
don't want.
As an example make a brush of
dimensions 192x192x192. Don't worry about making it
into a map because to explain clipping you only need to look
at the editor. Now suppose you want to make this brush
into a wedge. This is what you must do. With the
shape you want to clip selected go to the selection menu and
choose clipper then click toggle clipper. Now mark one
point in one corner and another point in the opposite
corner. A line will be drawn between them. The
line will be drawn around the part of the shape that will be
removed. If this shows that the wrong part of the shape
will be clipped then in the clipper menu all you have to do is
choose flip clip orientation. When you are satisfied the
right part will be clipped in the clipper menu choose clip
selection. This will remove the part of the brush you
chose to clip. You can do this any number of times to
make the brush the shape you want. With clipping it is
even possible to create a curved effect if you keep clipping
the corners of your brush.

However do remember that the
more you clip, the more faces a brush has. The more
faces it has the slower it will make your map run when it is
being rendered onscreen in the game.
JUNIOR...
This is that lighting effect
that I mentioned. You may have wondered why in your
maps the weapon in your hand and other players appear blacked
out, as though there is no light. This is because you
have to use the junior entity! A junior entity is a
light source just like any other, except for it lights the
player, your enemies and items. Place a junior near all
your light sources and press K to make the colour in line with
the colour of lighting you want to use.
Just the same as a normal light
source when you press N you can use the light key to modify
how bright the entity is.
