When you say "card", are you talking about the buttons on the NIF export screen? If so, that is 1/2 of the equation...although the most important half. The other part is the actual collision model and the settings on the Actor tab (Rigid, Static, material values, etc.) The NIF scripts might be advanced enough to overwrite the model settings (especially if you forget to set them) but I have not tested that scenario out. LHammonds Yep, I meant the button :biggrin: The most useful part of this is that you can put books into bookshelves that can't be moved, therefore the player can't accidentally move them, take em or etc...I used it to put an inkwell on a desk..which is really hard if you try to do it in-game and a lot less effective.
