How to install blood FX (BFX) in FiveM

A BFX pack changes what you see when you hit someone: the blood, the impact and often the bullet tracer. Installing one takes two files and two folders. Here is exactly where they go.

What is in a BFX pack

Almost every FiveM blood FX pack has two parts:

  • an .rpf file with the effects themselves (the particles you see on a hit)
  • a bloodfx.dat file that tells the game which effect to play for which hit

Some packs only have the .rpf. That is fine: you just skip the bloodfx.dat step.

Find your FiveM folder

  1. Right-click your FiveM shortcut and choose Open file location.
  2. Open the FiveM.app folder. This is where every client mod goes.

The usual path is %LOCALAPPDATA%\FiveM\FiveM.app. Paste that into the File Explorer address bar to jump straight there.

Install the BFX by hand

  1. Close FiveM completely. Files that are in use won't copy.
  2. Back up your old BFX. Copy anything you are about to replace into a folder on your desktop, so you can go back.
  3. Put the .rpf in the mods folder: FiveM.app\mods\. Make the mods folder if it doesn't exist.
  4. Put bloodfx.dat in: FiveM.app\citizen\common\data\effects\ and replace the old one.
  5. Start FiveM and join a server to see it.

Seeing an effect in game before you install it saves a lot of trial and error.

BFX not showing? Check these

  • Two packs at once. If an older BFX .rpf with a different name is still in mods, the two can clash. Keep one BFX in mods at a time.
  • A separate tracer mod. Many BFX packs have their own tracer built in. A second tracer .rpf in mods clashes with it and one of them stops showing.
  • Wrong folder for bloodfx.dat. It has to be in citizen\common\data\effects, not in mods.
  • The server. Some servers limit custom client files. Check your server's rules.

The one-click way

The Blood FX Tool has an Install to FiveM button. It puts both files in the right place, backs up every file it replaces into a dated folder first, moves an older BFX out of the way so two packs never clash, and can undo the last install.

FAQ

Where do I put a BFX .rpf in FiveM?

In FiveM.app\mods\. Create the mods folder if it is not there.

Where does bloodfx.dat go?

In FiveM.app\citizen\common\data\effects\, replacing the file that is there.

Can I use two BFX packs at the same time?

No. Two BFX files in mods clash, and usually only one shows. Keep one at a time.

How do I remove a BFX?

Delete its .rpf from mods and put your backed-up bloodfx.dat back. The Blood FX Tool can undo its last install for you.
