I'll just have to forget it for now becuase I'm having another problem which I tried to solve alone but failed:
Does anyone know how to solve this?
Error: Texture 'class201_tf(k)_body/main window _first_-main window.texture' is missing or could not be loaded for mesh 'class201_tf(k)_body\class201_tf(k)_body.im'.
Does anyone know how to solve this?
