i also don't think this is where you would post this
i think this goes in both sections
it's modification, so probably belongs in the modification part of the forums
and I don't think vehicles have bones, just a collision box(es)
and probably would've seen the post describing how to do it if it were in the right section
Now, for collision. This has to be a low poly outline of your model, preferably just a cube. And in order for it to work you must make a new empty and name it Col0. Then parent your cube to Col0 and parent Col0 to shape. If you don't know what i'm talking about go to the weapons/items chapter.
Make sure you name your cube Col, I don't know why but the game will start complaining in the console that it needs to be named Col, or LosCol. It does no harm but people don't like having console spam in their console.
