After piddling around with PRC a bit, I decided I wanted more race models to use for PRC's many, many races. I figured CEP and the merged PRC hak would be the way to go.
I reinstalled NWN, installed the latest version of CEP, the latest version of PRC and then I used the module updater to add the merged hak and the ocfix to the Official campaign to test it out.
Minor problem, the character creator doesn't seem to show CEP's new creature models, only the PRC/NWN1.69 creature models. Did I do something wrong, or do I need another java creator thingy?
