With the code I have it would be as easy as setting the helmtexture to the proper herosforge id. You can mix and match herosforge and regular armor textures.

Was this ever merged into the main repository? I've run into this problem as well (with the texture GM commands not working), so I assume not. Just want to check first though.

Just checked my source. The code appears to be in there (checked zonedump.h). I'm guessing there's another problem then, because the # commands aren't working as I'd expect.
