Here you go, Dave. There are two versions in the package, you want
BFF0_4_3.ms since the other doesn't work with Max 9 and later. I have no idea if it will still work with Max 2017, I'm still on 2008 but it's mine and not a continuing subscription.

What the script does is write a whole collection of scripts to a specified folder. These scripts rebuild the model in Gmax when you run the top-level directory script from within Gmax. Takes a little time, and sometimes it's better to export selections from the model at a time if you're piling up the polys, since Gmax is still limited to that 2GB memory segment, maximum. I find textures should be .jpg or .bmp (IIRC) or the script coughs, so batch convert those .PSD multi-layer jobs.
Any other questions, I'm around or PM me.
