Wings Workflow
I'm starting to get a grip on this
process, I think... but if somebody
wants to 'splain more about all the
import/export options, I'd really
'preciate it!
Ah, very
good.
I do one of two things with VRML.
If I don't already have a Strata file
started
to use the VRML file in, I just drag the VRML file onto the
Strata
icon, Strata gives me a dialog with a
scale factor (should initially be 72
or 720,
I forget which)
72 is usually god
enough. If you see small triangles rendering as black
or
missing in your test renders, you need to
use a larger scale factor. The
black
triangles indicate that the distances are too small for Strata
to
render, and a larger scale will get it
into Strata's renderable size
range.
Then you are ready to apply your
smoothing value, usually a broad range
of
values can work, but you will want to do
test renders ( or just watch in
smooth
shaded) to see what is best. Depending upon your model, 30-89°
is
often a good place to start. Some models
will have a specific range which
works best.
If you have too low a value, you will see stepping in
your
shading where you want smooth shading.
If you see unwanted crumples and
bends in the
surface, the value is probably too high. This is really easy
to
get a feel for by taking a model and
setting a wide range of values, and
seeing
what happens. You can preview the effect by viewing in open
GL
shaded.
Since
the above method is for direct "open" your mesh will take
the
smoothing value at the main modeling
level of you Strata project.
The
alternative is to "import" the model into an existing file. When
you
import, you will get the same scale
dialog initially, but after the model
is
imported, it will be shown in your main
working space, but what you see in
the
working space is an instance, the model will have been made into
a
shape, and to get to the raw mesh to apply
smoothing, etc., you will need
to
double-click it to get to the root for
editing.
No need to convert to
polymesh, it is a polymesh: you just need to find
the
root
shape.
That is the import/open dance.
Not much to it, but maybe it is
the
difference between opening and importing
(open is direct open, import
creates a shape
and instance) that you need to sort
out.
You may also have questions about
smoothing in Wings, if so, that's
another
topic. One related Strata item,
though, is that if you mesh is pretty
crude,
you may need to enable "interpolate
polygon mesh shadows" in your Strata
render.
You really need to experiment and get a feel for this with your
own
models.
