My sword is invisible in the game (Gothic 2)

Hi all,

I have my own sword had created. I have all the scripts correctly written, but when I'm Gothic and I go through Marvin I bring a sword, he's invisible! Since I'm on the sword put the color blue I see his image but the texture is not visible. Only the sword with the texture seen in the Spacer and in the game there. Also when I run in the direction mecha Hero repels as if it were a wall.

Texture (.tga) I 24-bit and lies in _work/data/Textures/Items

Why is my invisible sword?
