Switching to the glTF format for the tank model will cause a ClassCastException on line 69: Geometry tankGeom = (Geometry) tank.getChild(0);. Due to the glTF loader's node structure, tank.getChild(0) is now a Node. You should update line 69 to correctly locate the geometry within the new hierarchy, perhaps by using a recursive search.

This helper method is duplicated in TestBatchLod.java. Consider moving it to a common utility class to improve maintainability. Additionally, the fully qualified class name com.jme3.scene.Spatial is redundant here as Spatial is already imported.

Switching to the glTF format for the teapot model will cause a ClassCastException on line 60. The glTF loader introduces a wrapper node hierarchy, meaning teapotNode.getChild(0) will return a Node instead of a Geometry. This test should be updated to use a recursive search for the geometry, similar to the findFirstGeometry() helper method implemented in TestSSAO2.java or TestBatchLod.java.

Replacing the Sinbad character model with just his sword significantly reduces the complexity of this texture atlas test. If the full Sinbad character model is not available in glTF, consider using another character model (like Elephant.gltf or Ninja.gltf) to maintain the test's original intent of batching multiple complex models with distinct textures.
