WARNING: Fixed function technique 'Default' was ignored for material Common/MatDefs/Terrain/HeightBasedTerrain.j3md

[capdevon]

When assigning Material HeightBasedTerrain.j3md to a Terrain, the following log message appears on the console during application startup:

Material mat = new Material(assetManager, "Commons/MatDefs/Terrain/HeightBasedTerrain.j3md");
...
Terrain terrain = ...;
terrain.setMaterial(mat);

WARNING: Fixed function technique 'Default' was ignored for material Common/MatDefs/Terrain/HeightBasedTerrain.j3md

In fact, the definition of a technique in the HeightBasedTerrain.j3md file is incomplete and I believe it can be removed.
By removing the empty technique block, the warning log message no longer appears.

If you agree, I will create a PR.

Here is the corrected file:

MaterialDef Terrain {

	MaterialParameters {
		...
	}

	Technique {
		VertexShader GLSL100:   MatDefs/Terrain/HeightBasedTerrain.vert
		FragmentShader GLSL100: MatDefs/Terrain/HeightBasedTerrain.frag

		WorldParameters {
			WorldViewProjectionMatrix
			WorldMatrix
			NormalMatrix
		}
	}

	// -- This definition block can be removed
	//Technique {
	//}

}

Edit:
The same problem appears in the Terrain.j3md file

Thanks for documenting the issue.
