Making
arches (bevel method)
This method
of making arches is seen by many to be the most efficient as it cause
less if any sparklies as a pose to the
end cap way of making an arch which
might cause some sparklies (much more visible on 16 bit coloured cards).
Its up to you which method you want to use, this method is the best
though.
| 1. |
First
up lets sort out where the arch needs to be placed. Ive made
a simple tunnel, fig 1.0
(Fig 1.0)
|
| 2. |
Now
we need to create a brush for the first bevel, this is going
to be half of the arch. So create it half way across the width
of the tunnel, fig 1.2 and fig 1.3
 |
(Fig .1.2 Top view)
|
 |
| (Fig
1.3 Camera view) |
If you look at the brush we created (in red) if I was to make
it longer, by that I mean if I moved it up in fig 1.2 then when
I made my bevel it would end up being a more tight curve.
|
| 3. |
Now
with your brush selected go to "curve" and then chose
"bevel" from the toolbar, it will now create a bevel
out of the brush, fig 1.4
(Fig 1.4)
As you can see its not facing the correct way or at the right
angle, what we need to do is rotate it using the rotate buttons,
fig 1.5
(Fig 1.5)
Ive had to press the X>x button, its then facing the right
way, so I have then moved it into position on the right side
of the tunnel, fig 1.6, 1.7 and 1.8
(Fig 1.6)
(Fig 1.7)
(Fig 1.8)
You can see that the face or texture is facing the wrong way
(see fig 1.6). What we need to do here is go to "curve"
then "matrix" then chose "invert" it will
then move the face to where we need it, fig 1.7
(Fig 1.7)
What we now need to do is stretch out the piece so its the length
of the tunnel, the texture will stretch as well though, so what
we need to do now is make the texture go natural. To do this
select the piece of arch and then press "s" to bring
up the texture applicator, and then press the "natural"
button and then "done" (you can also use the curve
texture applicator for some texture movement, to use that press
shift and s)

Go
to "curve" and then "cap selection" and
a window will pop up, fig 1.8
(Fig 1.8)
The parts in blue are the parts that will be the new brushes/patches,
although our arch is facing the other way to that of the picture,
we need an inverted bevel, you can see it is the same shape
as our half arch only facing the other way, it doesnt matter
that its facing the other way in the picture, it will make it
properly, so choose "inverted bevel" and then press
"ok", fig 1.9, fig 2.0
(fig 1.9)
(Fig 2.0)
You can see that the texture on the front has actually aligned
up, so theres no need to align it, if it doesnt align up for
you, try using the curve surface inspector (hold shift and press
s)

Now
we have half an arch. Before we copy it, ive stretched mine
out to the length of the tunnel. All you then need to do is
select the arch piece and press "space" to copy and
paste it and then you need to press "x|x" on the toolbar
for it to rotate to face the correct way. Then you need to move
it into place, or move it into place and then press the "x\x"
on the toolbar, its up to you, as long as you now have a full
arch, fig 2.1
(Fig 2.1)
|
| 6. |
You
will notice the brick texture on this arch on the inside are
going length ways, you can rotate them if you wish so there
like real bricks (horizontal) you can hold shift and press s,
to bring up the curve texture window.
Its difficult to align brick textures with the brush walls on
arches, often you will see people use plain textures or leave
them as they are in fig 2.1, or you might have an arch texture
if you are making a smaller arch.

Now we
need to caulk behind the arch where you cant see, as we can
see our arch doesnt go all the way to the floor so we need
to make some more brushes. See fig 2.2 and 2.3
(fig 2.2)
First lift up the 2 walls and then add some new walls below
them, fig 2.3
(Fig 2.3)
|
| 8. |
Now
the top wall brushes can have the caulk texture applied to the
faces facing the arch, you need to also apply it to the ceiling
face that faces the arch, first hide your arch, press "h"
and then apply the caulk texture, fig 2.4
(Fig 2.4)
For even further optimisation we should move some vertices,
by this I mean move the walls into a triangle shape at the top
and the top ceiling brush needs some vertices to move, then
you need to caulk the faces that wont be seen. See fig 2.5,
fig 2.6, fig 2.8
(Fig 2.5)
(Fig 2.6)
(Fig 2.7)
(Fig 2.8)

Unhide
the arch by pressing "shift" and "h", your
arch is now done. Go test it out.
Usually with this method no sparklies will appear and its easy
to align the textures where are in the end
cap method of making arches you might get some sparklies.
Ill leave it up to you which to use, there are tutorials on
both, its most peoples view that this bevel method is best.
(Note you dont see the white caulk
texture coming through in game obviously as thats invisible) |
