Hi all, Im still learning my way around JMonkey and Java. I’m just wondering how I can load a scene that I created in SceneComposer in my Simple application. The following code:
public class CustomTerrain extends SimpleApplication{
public static void main (String args[]){
CustomTerrain app = new CustomTerrain();
app.start();
}
public void simpleInitApp(){
Spatial scene = assetManager.loadModel("/Scenes/testScene2.j3o");
rootNode.attachChild(scene);
}
gives me an error ( I got the code from the HelloTerrain tutorial)
here is the error:
SEVERE: Uncaught exception thrown in Thread[LWJGL Renderer Thread,5,main]
com.jme3.renderer.RendererException: compile error in:ShaderSource[name=Common/MatDefs/Terrain/TerrainLighting.frag, defines, type=Fragment] error:0(125) : error C1008: undefined variable “m_DiffuseMap”
Thanks in advance 
It seems you save the j3o with another version of jme3 than you load it with.
