I've tried (

Basically what I did was to take a NPC head (missing hooks) and in GMax I copied a helper and renamed it as a GoggleHook and another as a MaskHook. I then exported from GMax and tried to recompile using mdlops. If I use the resulting mdl & mdx, I get the floating head. So, I tried hex editing the mdl, but I'm fishing in the dark. I'm have no idea which values to copy from the original mdl, and settoken hasn't clarified. I've used HexCmp program to compare multiple mdls, but I still don't know how far down the hex mdl I need to go. Sometimes I'll import an ascii mdl into GMax and export it without any changes, and recompile with mdlops... just so I'll have something else to compare to the original. :headbump :migraine:
I'm still hoping that someone with more skill than I will figure it out (nudge, nudge Svosh). If you give it a try Ferc, and something clicks, please let me know. I'll never say that it is impossible, it's just beyond my current capabilities.
