[PL] Track props don't show up in game

[VintageEpicFail]

Okay, so the problem is that some of the tracks on my pl_ map don't show up in game.
Here's what it looks like.

Hammer View
In-Game View

As you can see in the in-game view, the tracks are visible until we reach the top of the hill.
Anyone got any suggestions?
Thanks

That's very odd. The only think I can think of, is that you've got a fatal error in VBSP and your changes aren't compiling since you layed the tracks on top of that hill.

Run your compile log through this: http://www.interlopers.net/index.php?page=errors and report back.

Oh, silly me, I've just been doing quick tests so I never bothered to put in a skybox. The link you gave me said something about the model being exposed to the black void or something along those lines and that pointed me the right way. Thank you

EDIT:
Ok, so I got the cart moving but it won't go around any corners
I'll show what I mean

Guessing since we can't see the path_tracks, but I'd say you've got them too low and the cart is getting stuck on the ground. It's a physics object, so everything needs to be clear for it to move through unimpeded

That worked thanks ym
