hi, I use shading like described in the thread “shading” (the normal way).
But I noticed that flat-shading is used so I tried to activate smooth goraud-shading. I created an ColoringAttributes-object, used setShadeModel(ColoringAttributes.SHADE_GOURAUD) and added it to the object’s Appearance. But no difference can be seen.
So thx for help 
Haeh?? isn’t Gouraudshading the default?
Edit: maybe you set your normals wrong?
