Hi all, I am trying out the CartoonEdgeFilter in my game!
It looks good! However there is one problem: It ignores my terrain.
Hence, the terrain does not have a cartoon edge. And, even worse, the cartoon edge appears through the terrain!!
The terrain is created like this:
public void setUpTerrain(){
//assetManager.clearCache();
treeShape = null;
if (terrain != null){
terrain.removeFromParent();
}
if (landscape != null){
bulletAppState.getPhysicsSpace().remove(landscape);
landscape.destroy();
}
while (CURRENT_MAP == 0 || CURRENT_MAP == 1000){
//Do nothing
try{
Thread.sleep(100);
}catch (Exception e2){
}
System.out.println("Waiting for server to choose the map!");
}
if (CURRENT_MAP <= 4){
if (guiNode.hasChild(pic1)){
pic1.removeFromParent();
}
mat_terrain = new Material(assetManager,
"Common/MatDefs/Terrain/Terrain.j3md");
//mat_terrain.setFloat("Shininess", 5f);
//We need to wait until the server has chosen a map. Waiting here...
//mat_terrain.setBoolean("isTerrainGrid", false);
//mat_terrain.setBoolean("useTriPlanarMapping", false);
// mat_terrain.setBoolean("WardIso", true);
//mat_terrain.setFloat("Shininess", 0);

dirtTex = "Textures/Terrain/dirt.jpg";
tile*=2;
}
Texture normM = assetManager.loadTexture("Textures/Terrain/road_normal.png");
normM.setWrap(WrapMode.Repeat);
Texture grass = assetManager.loadTexture(
grassTex);
if (!minimalQuality){
grass.setAnisotropicFilter(anisotropic);
normM.setAnisotropicFilter(anisotropic);
}
grass.setWrap(WrapMode.Repeat);
mat_terrain.setTexture("Tex1", grass);

//mat_terrain.setTexture("NormalMap_1", normM);
/** 1.4) Add ROAD texture into the blue layer (Tex3) */
Texture rock = assetManager.loadTexture(
rockTex);
if (!minimalQuality){
rock.setAnisotropicFilter(anisotropic);
}
rock.setWrap(WrapMode.Repeat);
mat_terrain.setTexture("Tex3", rock);
mat_terrain.setFloat("Tex3Scale", 24f * tile);
//mat_terrain.setTexture("NormalMap_2", normM);
}else{
setUpTerrainTextures(assetManager);
}

Yes, the terrain code is messy and needs tidying up and some is copied from tutorials. Don’t kill me please. 
I just don’t understand why this this issue is happening.
The terrain uses a custom material and shader (slightly modified from Lighting.j3md).
Edit: issue only occurs if CURRENT_MAP <= 4.
