I have just started to implement some very simple experiments with JME3 SDK.
A textured quad using Unshaded.j3md works fine, but trying the same thing with Lighting.j3md gives an error:
INFO: Uniform m_VertexColor is not declared in shader [ShaderSource[name=Common/MatDefs/Misc/Unshaded.vert, defines, type=Vertex], ShaderSource[name=Common/MatDefs/Misc/Unshaded.frag, defines, type=Fragment]].
The code:
[java]
public void simpleInitApp()
{
Quad q = new Quad(1.0f, 1.0f);
Geometry g = new Geometry("Quad", q);
Material m = new Material(assetManager, "Common/MatDefs/Light/Lighting.j3md");
g.setMaterial(m);
Texture t1 = assetManager.loadTexture("Textures/green_square.png");
m.setTexture("DiffuseMap", t1);
rootNode.attachChild(g);
}
[/java]
Its not an error, its an “INFO”, see the beginning of the log message
True 
To be clear, the error is that nothing gets displayed.
I presume that this shader works just fine (it’s part of the SDK) so it’s a newbie config/app issue.
The code works if I use Unshaded.j3md.
[java]
public void simpleInitApp()
{
Quad q = new Quad(1.0f, 1.0f);
Geometry g = new Geometry(“Quad”, q);
Material m = new Material(assetManager, “Common/MatDefs/Misc/Unshaded.j3md”);
g.setMaterial(m);
Texture t = assetManager.loadTexture(“Textures/green_square.png”);
m.setTexture(“ColorMap”, t);
rootNode.attachChild(g);
}
[/java]
Oh, in that case you don’t have a light …
