Errors after batching

Skatty · May 29, 2014, 3:37pm

Hello!

About 1 month ago I batched my map and it worked perfet! Loading decreased from 3mins to 30sec! I used back my non-batched map to edit it. Now I added few new models and try to batch again. After I run my game I get strange error:
(thought it was caused by mill rotating control but even without mill on the map it exist)

EDIT: It was caused by batching terrain. Now I fixed but get that error

Here’s the method part: (error is at line 6: [java]LodGenerator lodGenerator = new LodGenerator(g);)[/java]
[java]if (spatial instanceof Geometry) {

            Geometry g = (Geometry) spatial;

            LodGenerator lodGenerator = new LodGenerator(g);
            lodGenerator.bakeLods(LodGenerator.TriangleReductionMethod.PROPORTIONAL,
            0.1f, 0.2f, 0.3f, 0.4f, 0.5f, 0.6f, 0.7f, 0.8f, 0.9f);

          //System.out.println("Found geometry " + g.getName() + " = " + g.getMesh().getNumLodLevels());
            
            LODControl lod = new LODControl(10); //Change this value for distance to change LOD
            g.addControl(lod);

            
        } else if (spatial instanceof Node) {
            Node node = (Node) spatial;
            for (int i = 0; i &lt; node.getQuantity(); i++) {
                Spatial child = node.getChild(i);
                parseSceneForLOD(child);
            }[/java]
