3ds Max vehicle to hl2 Thread

i have already modeled out some vehicles in 3ds max, however i dont know how to get them into HL2.... anyone know of any tutorials i can read on how to accomplish this?

Valve-erc.com

Have you tried this?

actually, i have, both google, and the sdk web page stuff.... i cant figure out how to get the stuff into xsi, or into the game from there. im having trouble finding tutorials of how to do the steps like making the colision model, and the physics for the tires and ect. what they show you in the sdk stuff is great conecpt stuff, but not step by step how to do something

I'm going to suffer this soon
