Modding How do I spawn as any drivable biped in campaign missions

[Abuzi 1]

How do I spawn as any biped such as a brute, marine, etc in a campaign mission? I figured that I didn't really want to spawn a biped every time I wanted to drive a biped so I was wondering if anyone knows how to swap the starting character (ex: Master chief) with a biped as well as give it the ability to be driven?

A seat is not required to do this specifically:

Jump into the game globals tag (matg) and look for "Third Person Unit", in campaign missions there will be 4 block indexes each one is different.

You can actually set your third person unit as a vehicle, it has some interesting results. (I remember doing this by accident back around 2005-6ish with Halo CE)

By the way if you are getting a black screen or are just not actually spawning at all, the reason is because the bipd you selected is not actually being loaded into the game because of the zoneset. You will have to jump into the scnr and enable the relevant designer zone sets on the BSP(s) you are using.
