Have you made any attempts at this yet? Post what you have so far! (people will help you, but won’t just give you the code)

Gustavo Borbas? Is that you?

Hello!

[java]

for (int i=0; i < chunkMap.getMap().size(); i++) {

// I save data in HashMap

// get key from HashMap

Vector3f key = (Vector3f)chunkMap.getMap().keySet().toArray();

// get value from HashMap

Chunk ch = (Chunk)chunkMap.getMap().values().toArray();

Mesh val = ch.createMeshChunkMesh();

// Create geometry from CustomMesh

Geometry geom = createGeometry(val, ch.getChunkLabel(key));

// And attache to the root node…

rootNode.attachChild(geom);

}[/java]

I attached to the rootNode 2 custom mesh.

What output I have expected:

P.S.
(31.0, 9.0, 15.0) was added last to the rootNode

seems somewhere my mistake
