HaloMods "Classic" Read-only Archive

I am working on a mod for containment it is a mach mod and I wanted the machs to be normal so I could skin them but when I did that the map went over 80 mb. >_< So I restarted and I forgot all about the invisible barriers and now I am trying to get rid of them by moving it in MilkShape then injecting it back into the map. But when I File> Import > Wavefront OBJ then import it nothing shows up. Could someone please help me?

What are you using to extract it? I would suggest using Team Expisor's SBSP Tools.

Yes that is what I am using.
