What material are they using?

Teapot uses the normal map. ?

 val m_teapot = Material(assetManager, "Common/MatDefs/Misc/ShowNormals.j3md")
 teapot.setMaterial(m_teapot)

Wall is unshaded and has a jpg set as texture;

 val m_wall = Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md")
 m_wall.setTexture("ColorMap", assetManager.loadTexture("Textures/Terrain/BrickWall/BrickWall.jpg"))
 wall.material = m_wall

So… continuing the “Socratic method”…

What do you suppose “Unshaded” means as opposed to “Lighting”?
