BatchNode reset Line Mesh

Hi team,

I am having some what of a problem.
When I add Line Mesh Geometries to a BatchNode after calling the batchNode.batch(); it seems as if the line width of each line which is 5f is reset to 1f.

Is this a known bug and is there some way to fix it.


Here is the sample code:

import com.jme3.material.Material;
import com.jme3.math.Vector3f;
import com.jme3.scene.BatchNode;
import com.jme3.scene.Geometry;
import com.jme3.scene.shape.Line;

public class TestBatchLine extends SimpleApplication {
    private BatchNode batchNode;
    public static void main(String[] args) {
        TestBatchLine app = new TestBatchLine();

    public void simpleInitApp() {
        batchNode = new BatchNode("drawing");
        addLine(Vector3f.ZERO, new Vector3f(0, 2, 0));
        addLine(new Vector3f(0, 2, 0), new Vector3f(2, 2, 0));
    protected void addLine(Vector3f start, Vector3f end) {
        Material mat = assetManager.loadMaterial("Common/Materials/RedColor.j3m");
        Line line = new Line(start, end);
        Geometry geometry = new Geometry("line_geom", line);

Never tested to batch lines tbh, I’m gona look into it.
Thanks for the test case.

I guess Line is a class of yours isn’t it?
Could you post it too?

Thanks @nehon,
No, line is a jME3 class.

I have updated the imports for the test case above.

doh ok …

Ok that’s fixed, though all meshes needs to have the same line width.

Wow, thanks @nehon.

@nehon, can I only get that fix in the latest github?
Is there any other way to get it?
I am using stable jME3.0.

You can try to grab the BatchNode code and make it a MyOwnBatchNode in your project.
It doesn’t have any interaction with thte rest of the engine so it should work.
