If I generate a custom PDA and place into the extras/pda folder on an MP server, will players pull from it? Can it be used by them? Or are they restricted to their client PDA?
Im not sure, but I do believe it can be used in MP, in scenarios. I haven't actually done it yet, but you could open some of the other scenarios that have a PDA and suss out how they did it.
Yes, all player clients will pull from the server PDA, not the clients. I have my own dedicated server, and we have been using a custom PDA, for the last couple months now.
