Is there a way to specify the different shading models?
For example, if I turn the lighting off, I get Gouraud shading interpolation, correct?
What are the different shading models and how to specify them within JME?
you can set the Shading type with the ShadeState:
ShadeState ss = renderer.createShadeState();
ss.setShadeMode(ShadeMode.Flat); // Flat or Smooth
node.setRenderState(ss);
or you can of course use any GLSL shaders see jmetest.renderer.loader.TestNormalmap
