Ok I have spent 8 hours today trying to figure this out/find a tutorial on this. I am trying to make a replacement mesh for the default bodies in Fallout New Vegas. I found quite a few on how to make static items and even a few on how to make armor, and I even tried to modify the tutorials on how to make armor to work with the bodies. Nothing seems to work. I have all the appropriate plugins for max and I thought I would start out simple and merely modify a model that I know already worked so I used the .inf for a body replacer I downloaded. I imported it modified the mesh and then exported it. When I started up the game all I got was a screen full of disjointed polygons. I then went through too many forum posts to think about trying to find the answer. I eventually tried just importing the pre made .inf, not changing a thing, and export it. It was only a marginal success with the body completely missing now leaving me a floating head and hands. I know this is not an impossible task and I would like to know how to do this. If I ever get this figured out I plan on making a detailed tutorial to guide others through similar problems.
