How a BFX is built
GTA's effects are made of particles: small sprites with a colour, size, speed and lifetime. A blood FX pack changes those particles and tells the game which ones to play on a hit (that list is the bloodfx.dat file).
That means you can make a new BFX by changing three things:
- Which effect plays on a hit (blood, smoke, sparks, anything)
- How it looks: colour, size, speed, glow
- The tracer: the line the bullet leaves
Make one step by step
- Pick an effect. Browse effects by type (blood, smoke, impacts, explosions) and watch each one play in game before choosing.
- Change the colour. Turn red blood blue, black, neon, anything. Pick from a colour wheel or type the values.
- Add a logo or GIF (optional). Import a picture or an animated GIF and it pops on every hit.
- Pick a tracer. Squiggly, black, shrunk or rainbow, or any colour, with size, speed and glow.
- Build and install. You get an .rpf and a bloodfx.dat. See how to install a BFX.
Logo and GIF BFX
A logo BFX shows your picture on every hit. You can show it with a star flare, as a shiny metal or glassy ghost logo, or as lots of tiny 3D copies that burst out and bounce. Animated GIFs work too.
Tips for a clean BFX
- Bright colours read better on dark skies. Test your BFX on a day and a night sky.
- Keep only one BFX in your
modsfolder. - If your BFX has its own tracer, remove any separate tracer mod.
