@lostclimate I mean hard is relativ. Things you have to do:

1) Include Game Edit:
Code:

---

path "C:\\Programme\\Beta\\Map-Editor\\Scripts";
path "C:\\Programme\\Beta\\Map-Editor\\Hud Data";
path "C:\\Programme\\Beta\\Map-Editor\\Modelle";
resource "C:\\Programme\\Beta\\Map-Editor\\Scripts\\GEdit_Scripts.wrs";
include <material_editor.wdl>;

---

2) Init GameEdit in your main function
Code:

---

material_init();

---

Thats all

@Firo: fixed, thanks for the hint
