Hi
this is simple test code :
public void simpleInitApp() {
Sphere s1=new Sphere(15, 20, 3);
Geometry geom = new Geometry("Sphere1", s1);
Material mat = new Material(assetManager,
"Common/MatDefs/Light/Lighting.j3md");
mat.setBoolean("UseMaterialColors", true);
mat.setColor("Diffuse", new ColorRGBA(1, 1, 200, 0.5f));
mat.setColor("Ambient", ColorRGBA.White);
mat.setColor("Specular", new ColorRGBA(1, 1, 1, 0.5f));
mat.getAdditionalRenderState().setBlendMode(BlendMode.Alpha);
geom.setMaterial(mat); // assign the material to geometry
geom.setQueueBucket(Bucket.Transparent);
rootNode.attachChild(geom); // make geometry appear in scene
Sphere s2=new Sphere(15, 20, 1);
Geometry geom2=new Geometry("Sphere2",s2);
Material mat2 = new Material(assetManager,
"Common/MatDefs/Light/Lighting.j3md"); // create a simple material
mat2.setBoolean("UseMaterialColors", true);
mat2.setColor("Diffuse", ColorRGBA.Orange);
mat2.setColor("Ambient", ColorRGBA.White);
mat2.setColor("Specular", new ColorRGBA(1, 1, 1, 0.5f));
geom2.setMaterial(mat2); // assign the material to geometry
rootNode.attachChild(geom2);
/** A white, directional light source */
DirectionalLight sun = new DirectionalLight();
sun.setDirection((new Vector3f(-0.5f, -0.5f, -0.5f)).normalizeLocal());
sun.setColor(ColorRGBA.White);
rootNode.addLight(sun);
}
the problem is if i remove this line :
mat.setColor("Ambient", ColorRGBA.White);
but keep this line :
mat2.setColor("Ambient", ColorRGBA.White);
(or vice verse)
I will get this exception at run time:

but if i remove both of them or keep both of them it will work with out exception.
the same will happen for
.setColor("Specular", new ColorRGBA(1, 1, 1, 0.5f));
and
.setColor("Diffuse", ...));
it works fine in 3.1 alpha 4 .
