Ok It's like this:
I have a train (func_train) that needs to be passable when i don't need it and not passable, when i need it.
I mean that I have 2 identical trains, just that one has a door for the player to step in. Once the player is inside, the door will close, the train with the door will dissapear and the real train will appear, and start.
Now I've tried doing it with renders, but they only made it invisible, not passable. So is there any other way for this?
Thanks in advance
