Also, I really like the how you got SFB-OP to use Andors, Tholians, and other SFB races. Can these race names be changed in OP so you don't have to use the Orion Cartel names?
Yes, as UAW does, but in the shiplist race column the original Cartel names must be used (though they need not be visible in game). There are limits on renaming races though, particularly on Dynaverse servers.
Ok, I checked the forums on this "ftr/PF Donation" idea and found more info on this SFB-OP mod. I can't download it now, but I read some stuff on it. It looks like some of the Pirate Cartel's Fighter are substituted for non-fighter races. Can Races use other races fighters on there ships?
Yes, but depending on the donation scheme used.
Now, concerning PF's, say you want to add Fed Thunderbolt PF's to the Federation, can you just make a "PF" slot in the ship list and have a Fed ship use that "PF" as a Fighter? Or do I have to use a Particular Races slot for PF's to be used by non-PF Races much like Fighters must be donated from other races?
Easiest way would be to copy a gorn PFT and PFs to the fed list, edit them as desired, then copy them back appending to the gorn list, such that the identical PFT and PFs are present in both the Gorn and Fed lists. (donors and receivers should be identical in all but the race column)
Additionally, donor races must be above the receiving race in the list. (for the above example place the Gorn at the top of the list above the Federation). It is best not to split races in the list, generally a race should be contiguous in the list.
Take a good look at an existing shiplist that uses donation that works well and go from there... (don't forget models! a frigate model sized down in the model.siz file for PFs can work well)
Donation of fighters is done similarly (but can require edits to the fighterlist as well, depending on how it is done).
