Vehicles modding for GTAIV trade secret:?

[AlphaWolF_uk]

Basically ive searched and searched the world wide web in vain for a tutorial on getting custom Vehicals in to gtaiv

the nly luck i had was finding a method to get the models in to 3dsmax with this video

but how to get them exported in a format that either open iv or spark can understand seems to be a trade secret ????

 

i use gims and openiv to do weapons and player skins but im clueless as how to do vehicles.

 

 

i dont really expect to get an answer here as most threads just seem to get viewed and thats it:((

lol, it's not a "secret". u simply need a registered version of Zmodeler. also u need to understand the hierarchy and material settings of the IV vehicles to make them work in the game
