The forums were freaking out on Drek and he asked me to copy and paste this in here for him.
"I had a post typed up and forgot to not copy paste other stuff.. Forum's always glitching. Anyways, the gist of it was - my installer provides you with object lists. Just use the objects from those lists and delete the .fho of those lists when you export your map. If I remember right FH can still read from object lists when in multiplayer. The reason I have it set up this way is to reduce the possibilities of issues. That - and if it wasn't this way there'd be many, many possibilities of duplicate particles.. duplicate meshes.. etc.
