I am using GMax to model ships for a HW 1 Mod that I am working on.

I want to use Gimp to edit the .lif files but I am uncertain how to convert them to be able to be used with Gimp and then back into a useable form so that they will work in the game.

Editing the .shp files is pretty easy but I need to know how to associate the models created in GMax with a new .shp files that will be a copy of the base .shp files but tweaked to my models so the new models will replace the standard Homeworld base ship and .shp files.

Thanks for the help.
