As a server admin, I have certain files (custom playermodels, for example) that I would like all clients to have regardless of what map the server is currently running. Adding all of the filenames to .res files for all of the maps on the server doesn't seem like the best option, especially since such files might periodically be added and removed. Some kind of text file where you just list files/folders would be ideal, especially if by listing a directory all of the files and subdirectories under it would also be implicitly added.
If possible, I'd like to avoid using an admin plugin like mani or sourcemod, but if there's no other way I'll go for it. In Gmod I just wrote Lua scripts for this kind of thing, but 10 hours of oc_harvest last week led me to try hosting a different game.
Extra credit if anyone knows how to force file consistency on the aforementioned files, too.
Thanks in advance!
