I think that you have to set the normals,

                Hey all,
        
                I’m having a problem with the appearance of a shape3d. I created a 
shape3d from a triangular array, which I obtained from object file geometry info. Now 
when I set appearance for this shape3d they do not work. Please help me out. I guess 
it’s the lighting problem which I have it enabled. Textureattributes work fine but 
not the lighting effects.
        
                Here is the piece of code
        
                
        
                TriangleArray ta1 = new TriangleArray (
        
                             2709,
        
                             TriangleArray.COORDINATES
        
                         );
        
                
        
                ta1.setCoordinates(0, coo1);
        
                 s = new Shape3D(ta1);
        
                
        
                Material m = new Material();
        
                    Appearance a = new Appearance();
        
                
        
                 //texturing takes place fine
        
                Texture tex = new TextureLoader(texImage, this).getTexture();
        
                            a.setTexture(tex);
        
                            TextureAttributes texAttr = new TextureAttributes();
        
                            texAttr.setTextureMode(TextureAttributes.MODULATE);
        
                            a.setTextureAttributes(texAttr);
        
                            a.setTexCoordGeneration( new 
TexCoordGeneration(TexCoordGeneration.OBJECT_LINEAR , 
TexCoordGeneration.TEXTURE_COORDINATE_3) );
        
                
        
                 //culling takes effect too
        
                PolygonAttributes pa = new PolygonAttributes();
        
                            pa.setCullFace(PolygonAttributes.CULL_NONE);
        
                            a.setPolygonAttributes(pa);
        
                
        
                //appearance does not take effect
        
                 m.setAmbientColor(1.0f, 1.0f, 1.0f);
        
                m.setDiffuseColor(1.0f, 1.0f, 1.0f);
        
                
        
                             m.setSpecularColor(0.3f, 0.3f, 0.3f);
        
                
        
                            m.setLightingEnable(true);
        
                            m.setShininess(100.0f);
        
                    a.setMaterial(m);
        
                s.setAppearance(a);
        
                
        
                objTrans.addChild(s);
        
                
        
                thanks
