Hey Wings disciples, this is a quick and dirty tutorial as to how to get a door or
flap to show up on a curved surface
in Wings for use in Orbiter
to...
and have it, the door be blended in with the curved surface when it's closed and not
stick out .
The simple way to do a curved surface, if I wanted this polygon to be a door would be
to
do a shell extrude
and
if we wanted it to be inside the surface
we'd give it a thickness of
point zero two, point zero one, we'll say
and
we
First off it's inside out, we have to invert it
and there's our door.
We want to give it
hard edges so that they're...
the edge's actually square--if the edges aren't marked as hard, they won't show up as 90 degree angles.
and in order to
and we hide or mark as a hole the
polygon on the original sphere that we were covering with the door
The problem with this is even though it looks okay in the modeling view, or in the polygon view,
we look at the smoothed view
the door is
obvious and it doesn't blend in with at the surface at all and it looks bad
and while this this is isn't Orbiter here, the smooth view in Wings is a pretty good approximation
of what it is going to look like in Orbiter.
So this isn't gonna work.
So, what we do
Whoops, broke it
uh... really broke it...
Okay, so what we do for this
if we want this to be our door,
we take all of the faces around it
and we include that and we extrude and since we don't need all of these to be as thick
as the door's going to be
we just do shell extrude
with a distance of
zero.
And what that does for us
is
it gives us
an extraction from the surface which is
the shape of the sphere and it sits on the sphere. We don't need these extra corners here
so we just do a "clean up" and it'll chop off the corners for us.
And to give our door thickness,
we just take the inner face of
the door face
and we
extrude that by point one, or however thick we want our door to be.
And then make sure that you
make those
edges hard,
because otherwise
they won't show up as
ninety degree angles.
However, even though it looks like they are,
note that the exterior edges are not marked as hard here, it's just that it's showing through
This edge right here is,
for example, not hard, it just shows through the mesh.
However, we don't want
all of these faces don't show up on the export to Orbiter, the only reason that they're here
is to give this surface the smoothness it needs in order to look like it's sitting
blended into the surface of the sphere.
In order to tell the Orbiter exporter
that we don't want the surfaces to show up
we give them a material named exclude -- "_exclude_"
And you can make this whatever you want, I just
give it an opacity of zero,
so it doesn't show up in the smoothed view here. And there's our door object and
if we...
so for what's under the door, for this case
you can
have this open onto whatever you want.
In this case I'm going to make the door sit in a small recess on the
surface of the sphere.
What you could do
to get that is to extrude this face
in
and there's your recess for the door, however at this point we have changed the surface of the sphere
by having
a face be set back from it and that changes the normals of the sphere and that's not
the look we're going for.
So we
cancel that
and we
again do a shell extrude except this time we do
just the face we want as the recess, and we'll do it negative
so if the door is point oh one we'll say we want the recess to be point oh five.
And
the face
on the surface of the sphere, of the original sphere here
also needs to be marked as exclude so it will not be exported to
Orbiter. And what we have in here is is this is where
our door or perhaps it's an access panel
or
or a flap or a speed brake or something and we need to make sure that that all these edges
