@BigBob, I would like to know if you are using jME unshaded terrain?
I have tried it but no luck yet. I did try all those other tips of changing the terrain material at runtime explained here:
Link to Unshaded terrain

This is what my code looks like:

public static void makeTerrainUnshaded(TerrainQuad terrainQuad) {
    SceneGraphVisitor sgv = new SceneGraphVisitor() {
        public void visit(Spatial spatial) {
            if (spatial instanceof Geometry) {
                Geometry geom = (Geometry) spatial;
                System.out.println("Parse Terrain -> " + geom);
                Material mat = new Material(SharedSystem.getInstance().getBaseApplication().getAssetManager(), "Common/MatDefs/Terrain/Terrain.j3md");
                mat.setBoolean("useTriPlanarMapping", false);
                mat.setTexture("Alpha", geom.getMaterial().getTextureParam("AlphaMap").getTextureValue());

                if (geom.getMaterial().getTextureParam("DiffuseMap") != null) {
                    mat.setTexture("Tex1", geom.getMaterial().getTextureParam("DiffuseMap").getTextureValue());
                    mat.getTextureParam("Tex1").getTextureValue().setWrap(Texture.WrapMode.Repeat);
                    mat.setFloat("Tex1Scale", Float.valueOf(geom.getMaterial().getParam("DiffuseMap_0_scale").getValueAsString()));
                }

                if (geom.getMaterial().getTextureParam("DiffuseMap_1") != null) {
                    mat.setTexture("Tex2", geom.getMaterial().getTextureParam("DiffuseMap_1").getTextureValue());
                    mat.getTextureParam("Tex2").getTextureValue().setWrap(Texture.WrapMode.Repeat);
                    mat.setFloat("Tex2Scale", Float.valueOf(geom.getMaterial().getParam("DiffuseMap_1_scale").getValueAsString()));
                }

                if (geom.getMaterial().getTextureParam("DiffuseMap_2") != null) {
                    mat.setTexture("Tex3", geom.getMaterial().getTextureParam("DiffuseMap_2").getTextureValue());
                    mat.getTextureParam("Tex3").getTextureValue().setWrap(Texture.WrapMode.Repeat);
                    mat.setFloat("Tex3Scale", Float.valueOf(geom.getMaterial().getParam("DiffuseMap_2_scale").getValueAsString()));
                }

                geom.setMaterial(mat);

            }
        }
    };
    terrainQuad.depthFirstTraversal(sgv);
}

And here is the black scene:

Please help if possible?
