Modding Back 4 Blood

[MrPlaner]

Hey there,

Wanted to get back to B4B with friends, thought we'd check out some mods on Nexus.
Some seem to work only offline, while others work pretty well Online.

Although I've seen some weird behavior, being hit and miss with modding.

Does anyone know a solid way to make mods work 100% of the time?
the -fileopenlog flag in properties doesn't seem to work as good as advertised under mods on Nexus, so I'm wondering if there is any other choice/way?

And I guess, do you think there is any chance for Devs to disable EAC for this game?
Would make at least that part 100 times easier and mods like Back 4 Change certainly spark the most interest for me tbh.

If you want mod support like Valve games on Source engine. Then answer is - not gona happened. Because devs are abandoned the game, read the news. Because it is Unreal engine game with bad support of modding tools. Valve games have official servers and dedicated, B4B only have official one and ofcourse no need to use mods on official servers (from devs view).
Some mods not working online because anticheat checking some files like modded hp etc and ban them. If they remove anticheat, what players do first: find some mods or hacks?
-fileopenlog is just command for Unreal engine to not check modded files, so you can start the game with mods. There some mods on Nexus that not working anymore even with -fileopenlog because they are old.

Because There is SERVER and CLIENTSIDE.
CLIENTSIDE mods like UI/Player models are not visible for other players (they will see default models, because their client is unmodified).
SERVERSIDE mods like (damage, movement speed, card bonus) will work for everyone.
So for models/UI/sounds - the only way is to force people download same mod you are using.

Actually not. Because it's UE, it's easy to unpack assets and modify them, recompiling with Unreal Engine again.
I already made a code changes for the game without any problems.

Thanks for the reply!

It ended up being a mix of Easy Anti Cheat and the mod files not being put together it seems.

One mod that was supposed to be an "overhaul" - Back 4 Change I believe, said that it would change AI, zombie behavior and give 30 card deck - but the deck wasn't working and using 2 mods that change the deck kinda crash the game.

Would love to have a way to locally host a server so all the mods would work, but I can't seem to find a way for that one - probably not possible.

Actually not. UE files are encrypted and you need a key to decrypt them. Ofcourse if you already have decription key that some coder find, it easy for you. But there planty UE games with even harder encrypted files and those games do not have modding support.

Doesn't it depend if the devs just want to "pak" the game or not?
Plus if we're talking strictly Back 4 Blood unpak'ing is pretty straightforward from what I seen online.

Not denying the point about the other games based on UE engine, just in this case it's not that bad I'd assume.

It's easy btw to mod the game (Back 4 Blood).
Just a few people are interested. All assets can be changed, even the whole game can be changed, everything can be recompiled with massive changes.
No one want to do.
