Aha, the Appearance that I am triyin to set I get it from a 3DS model loaded in the
application. What I do is: I load a 3DS object with a metal appearance, I get the
Appearance of this object with getAppearance() and I set this Appearance to the shapes
created with the GeomtryArrays, it doesn´t work. I have used this in other
applications and was working(I mean loading shapes, taking their Appearance and
setting to other shapes) but in the other applications the Appearance were set to
shapes also loaded from another 3DS model. I know that there is light because I used
the methos setColors() of the GeometryArray to try a color and it works.

Here is some sample code for setting the appearance for a Shape3D object (a
red colored XY-Plane):
Shape3D shape = new Shape3D();
TriangleStripArray geometry = new TriangleStripArray(4,
TriangleStripArray.COORDINATES, new int[] {4});
Point3d[] points = new Point3d[] {
new Point3d(1e6, 1e6, 0), new Point3d(-1e6, 1e6, 0),
new Point3d(-1e6, -1e6, 0), new Point3d(1e6, -1e6, 0)
};
geometry.setCoordinates(0, points);
shape.setGeometry(geometry);
Appearance appearance = new Appearance();
ColoringAttributes ca = new ColoringAttributes();
ca.setColor(new Color3f(1, 0, 0));
appearance.setColoringAttributes(ca);
Material material = new Material(new Color3f(0.2f, 0.2f, 0.2f), new
Color3f(0.1f, 0, 0), new Color3f(1, 0.8f, 0.8f), new Color3f(Color.WHITE),
64);
appearance.setMaterial(material);
shape.setAppearance(appearance);
I guess that your lighting is not enabled as well, since the shape should be
shaded when lighting is enabled. Check the setInfluencingBounds for your
lights to include your Shape3D.
