So, does anyone know what should be the general load order so textures don't go missing? I have so many weird missing textures, for example:

Episode 2; I just got the crowbar and the elevator plunged down; I walk out into this room, and everything is fine; in this same roome just beyond the fence the game loads in the next section; once the loading is done and I turn around, all of a sudden some of the rocks back in the previous section have missing textures and are pink.

And it gets even weirder than that; should I pick up these pink rocks with the gravity gun and then shoot them, the moment the rocks get launched; poof it's now got a texture.
