Does anyone know how to go about making a certain AI drive a vehicle which it normally doesn't? Say an Elite driving a warthog? I know it has something to do with the animations but I have no idea how to go about doing it.

When I want a marine to wield a rocket launcher I changed the weapon's label from rl to ar.

Maybe the w-driver in the warthog's seats section needs to be changed or the entire bipeds animation needs to be changed since I don't know if an elite would sit in the hog properly.

Unarmed marines in future Halo games would sit in a warthog standing in a T position so I'll assume the elite would do the same thing or something similar... Maybe try ripping some MP elite that can use vehicles and see how those tags are set up...

Or wait for an actual modding professional to explain this! I like to post help but I am afraid of being totally wrong...

Specific animations are required. Someone with the same vision as you may have created them in the past but where and when is beyond me.

The hack way is to change the seat names to something the Elite has an animation for.

Example; swap W-Driver to G-Driver.

But that's a hack way and comes with issues of it's own. Like can Marines drive a ghost (I think maybe?)
