i using this example to make my game
i want change the model when i change the BaseAppState to another BaseAppState
Use the initialize method to add spatials to your scene, and the cleanup method to remove spatials. Have each appstate keep track of which models are theirs. Be sure you are using stateManager.detach() which will remove the appstate from the manager and call the cleanup method. It actually calls setEnabled(false) before it removes the appstate so if you have any pause functionality in the onDisabled method be sure to close that out in cleanup as well.
this is my code

i can remove this model
Are you trying to remove the geometry or the ui elements along the bottom?
I’m not 100%, but can you confirm that your buttons are working? whenever I do buttons in lemur I use the following
Button b = new Button("Button");
b.addClickCommands(new Command(){
@Override
public void execute(Object source) {
//your code here
}
});
The geometry
I calling the geometry in main class
If you want the geometry to disappear but you’re creating it in the main class I suggest either moving it to a separate app state or make a method in your main along the lines of removeGeometry() and call that from your app state.
Did you go through the beginner tutorials on the wiki?
I begin my game from this example
Don’t tell me you’re already messing with network but didn’t do the starting tutorials.
Starting with a network example is not the best way to get started with jME3. You should first learn the basics about the scenegraph and so on. Believe me it is much more fun to start with a blue cube and the feeling that you understand every single line of your code than stating with a finished multiplayer game and knowing you can guess at most how one percent of it works. Those network examples are great for people who had mastered the beginner tutorials, created some simple games and want to go the next step. I give you the advice to start with these beginner examples. I guess everyone of the people who are helping you did it this way. And I say they are perfect to get started. Work your way through the examples and join the world of the monkeys:
https://jmonkeyengine.github.io/wiki/jme3.html#tutorials-for-beginners
Yes i messing with networking
And i understed some the code
I think the problem is becouse i load the model in main and i have to do it menu.class
What do you want to achieve? Should the geometry be removed after a button gets pressed? Do you know where it gets added to the scene?
We should maybe make a list of FPS mods and Game-Makers so we can cater to people who just want to change a few lines of code and say they made a game…

I finde the soluction using this code
getState(SiliconDioxideState.class).cleanup();
You are doing it completely wrong. The method you are calling here is supposed to be called by the engine itself.
Go read the information about appstates on the wiki in order to find the proper way to do this.
ok
if i use this code
getState(SiliconDioxideState.class).setEnabled(true);
This is okay, but you should read up on what AppStates are and how to use them.

tópico can be close the problem as been solved
