calling a node from another scene

[rich seal]

the reason i wanna do it in this way is cuz im exporting my mod as a pck file and so on, changing the game directly seems too.... dangerous..

ill explain the problem more in depth later on if someone answers me....

The scene has to be loaded first.
If this is a mod, the game itself should have some sort of hook that will load and use your new scene. Not the other way around.

If the game does not support mods like that, you would need to modify it to consider new scenes you throw in.
