I have this problem that I can not figure out now. I have geometry set with normals, but no vertex colors. I used a new Appearance() to build Shape3D. The objects look gray which is correct default color. But if I use
Material ma = new Material();
ma.setDiffuseColor(green); // green is Color3f object
ma.setLightingEnable(true);
Appearance app = new Appearance();
app.setMaterial(ma);The objects are total black. What was wrong here? Also when use the default appearance, I don't see any reflection from light, although I did set up directional light for the whole scene. Any guess is appreciated!
