I shall only create half
of the face to make teaching process a bit simpler.
To start with it is best to sketch a left profile of the face
and use it as a background image. But it is not really necessary.
So lets start with the
real stuff now:
First, create different cross-sections of the face as in the
Remember that all the
splines should have the same number of vertices and in the process
following, the 1st vertex of a spline would join with the first
vertex of other splines. So we can control the horizontal shape
of the face with the placement of vertices on the splines, at
this stage only.
Next, create an arc - 180 degrees (half the circle). This will
be used as a path to loft the above shapes on.
This is as follows:
Select the arc, and click on the "loft object " in
the create tab
and then on the loft
Now click on the get
shape button and then click on the first spline (anywhere).
This would place the spline on the arc and loft it along. It
would be a good option to keep the perspective viewport in "smooths
and highlights " shaded mode.You would see the lofted object
Now change the path percentage to 5% (highlighted with yellow
- also check the percentage option next to it)
then again click on the
get shape button and click on the second spline. Immediately
you should see the impact in the perspective viewport. Here
we are just specifying different shapes at different levels
of the path, and the s/w would connect them all (1st vertex
to first, 2nd to 2nd etc).
Repeat the same, changing path percentages, for all the shapes.
This is how my lofting looked.
Horrible!! I won't pull
all the vertices and put them in the right position. Well you
don't have to in order to fix it.
DO NOT check the skin checkbox in the skin parameter drop down.
This will keep our mesh visually simpler and easy to work on
further. Just leave the skin in shaded checked (which is
the default) so that the perspective shows the 3d object.
Now comes the true power of the software.
Select the lofted object and click on the modifier tab
The same settings as
we had for lofting appear here.
( We can play a little with the path steps in "surface
parameters" to get a smooth shape with the least path steps
- and have a lower poly count).
Click on the sub object and select shape option. Now we
can select any spline we lofted and "edit spline it".
This way you can edit the spline in 3D. Above that the s/w will
show the impact on the 3d model in real time. This is the reason
I suggested that skin checkbox should not be checked as now
we can edit the spline very comfortably.
We can also keep a mirror "instance" of this object
next to it to make a complete face and as we edit the spline
of one , the effect is mirrored on the other as well and we
can see the final complete face.
We can also add another spline at another level on the path.
To give a more organic look (in case of aliens, animals especially)
we can make further use of a displacement map. Just pick any
bmp with good number of shades and texture, and use it as a
So here's what I achieved in 3D Studio Rel 4.0 (not MAX) from
As you can see this gives
a little less flexibility then NURBS but is much simpler.
