but i don´t know how remove the model
i find soluction
with this code
this.Game.GameSystems.Remove(this);

logout and login from where? what world class? are you using a game engine?
(It seems you're having trouble explaining your problem in english, are you portuguese (in your profile it says you're in Viana do Castelo)? If so, send me a private message with your question in portuguese and I'll try to help you)
i find the soluction i only have to add a new line of code
this.Game.GameSystems.Remove(this);

I have no idea what language or library you are using, but be careful of calling a method like remove() with a this pointer or reference. If you access any members of the object following that line, it is likely to crash your application (depending on what language you are using).
C++ example:
ListOfThings things;
void removeThing(Thing *t)
{
things.remove(t);
}
class Thing
{
public:
void destroyMe()
{
remove(this);
print(health); // crash, this points to deallocated memory
}
int health;
};
It is normally better to remove things at a higher level than have an instance remove itself from a container.
i using sharpdx and i programaing in c#
when i use this Game.GameSystems.Remove(this);
the game gets completely crazy
my buttons start flashing for wile and stop
