[SCRIPT] How to make item unlootable?

[IWT]

you edit the item on the model editor and set its type to other than "Item"
so player can't pick it up.

i'm not sure what kind of interaction you want with other items, collision? combine?

As the item lays on the ground, unlootable, you can use other item on it.

And I'm not sure about model editor, is it possible to do it without, or how to do it?
