How to change a race from NPC to PC race

[Dami]

I've been looking in the editor again this morning, and the other Centaur's in HL ARE player races. I did think that the Centaur that you copied is one that you do not have the package for - so it won't let you access the material. Now I'm not sure. I've just loaded the Mordenkainen Centaur, renamed it, saved, test now and I can choose that too as a Player Race. (I did have to remove the Source from the copy first though.)
Your text file tells me the race details (of what you want) and looks like it's copied out of a book, but we need the HL USER file to see what you have selected or changed in HL.
