3.3.1 Texture Scaling

We're dealing with a sample ammo crate
from the previous two topics, and we want to adjust the textures appropriately
because they're not the right size. In a lot of cases, especially
when the brush and texture are both rectangular, you can obtain the appropriate
scaling by clicking on the "adjust texture on face" button. It looks
like the "select texture for selected face" button except this one has
a little "texture L" graphic on it:
-
-
Eureka! Now that's a useful
command!
-
-
Let's say, however, that we cannot obtain
the desired effect by using this miracle command. For instance, what
if we wanted to use only part of a texture, as in making a door out of
an entire wall. Look carefully at this image:
-
-
I really like the rustic-looking door
and I've created a brush to place the texture on, but I don't want the
rest of the wall present in the texture. In case you're wondering,
the texture is "dday/costore1". When I loaded the texture onto the
brush, it was automatically assigned a scale of 0.4 in both directions,
at least on this brush. I want to scale the texture up (make it bigger)
so that the rustic door part of the texture is the only part visible.
Let's click on the face in question (the one facing us) and take a look
at our options:
-
-
There are at least two ways to change
the texture's scale: 1. Type in a new scale, and 2. Stretch the texture
by dragging the ends of the "texture L". Let's try Option 1.
I'll take a wild guess and say that the texture scale should be changed
from 0.4 0.4 (x y) to 1 1:
-
-
The same effect could have been achieved
by pressing the "reset 1:1 texture scale button" shown below:
-
-
Not a bad guess, but we can only see
the very edge of the door part of the texture. In the next lesson,
we'll learn to move the texture around on the face. For now, let's
try scaling Option 2 by dragging the top of the "L" upwards; it's next
to the circled "2" above. But before we do, let's make sure the grid
is set on 1 pixel so we can really fine-tune the operation. This
grid selection button is also handy to keep in mind when moving/sizing
brushes and entities, as it determines the value the object will "jump":
-
-
Now let's drag the top end of the "L"
upwards so that the door fits vertically...
-
-
and likewise, we'll drag its left end
leftwards so it fits horizontally:
-
-
...and we obtain a similar result to
that which typing in the scale factors produces. We had better move
along to the next lesson to get this door looking decent.
