Particle effects

Particle effects are used frequently in Team Fortress 2 to serve as decorations or visual cues for both various in-game events and cosmetic purposes. Any particle effect can be attached to any item or model theoretically, however, some effects appear exclusively on items of a particular quality; for example, the Unusual effect only appear on items with the Unusual quality.

Status effects

Status effects are used to indicate a change in player state to other players. A common example would be the overheal particles emitted from an overhealed player or one that recently picked up a health kit.

G.R.U. skull effect

The G.R.U. skull effect is emitted when the Gloves of Running Urgently are wielded by the player.

Overheal effect

Main article: Overheal

When a player is overhealed by the Medic, the player will emit medical crosses. The overheal effect is also emitted when injured players pick up Health kits. It is also used on the Medi Gun beam itself.

Critical spark effect

Main articles: Critical hits, Übercharge

The critical spark effect is used to indicate that a player's weapon will deal critical damage. This is usually accompanied by a team-colored overlay on the weapon itself. It is also used on the Medi Gun and Kritzkrieg to indicate that a charge is ready to be deployed.

There is no known localized name for the Treasure Hat effect, but it is attached as a new particle system defined as "coin_spin". The particles from this effect are influenced by the movement of the wearer and will only be emitted when the player is in motion.

Notes

Particle effects that are attached to an item will not be visible to the player wielding it in first-person view.
Miscellaneous items with particle effects can create multiple effect combinations

Bugs

A bug exists in the particle effect ID system. If a headgear has two effects assigned to it, the system will instead add the particle effect ID's together, creating the wrong effect. This was discovered by Self Made Outback Intellectual owners after the Australian Christmas 2011 Update. Community Sparkle (4) and Genteel Pipe Smoke (28) created Orbiting Planets (32). BUG FIXED JAN 11th 2012

The above bug extends to the Unusual Bubble Pipe which has no visible effect (not even Pipe smoke) under most conditions. Only some Unusual Bubble Pipe hats will show an effect because the addition gives a result that falls without the bounds of the ID list of current particles.

Some clipping issues occur with certain effects when used in combination, with one effect showing in front and the other flickering in and out of view.

The Nuts & Bolts particle effect has a visual problem. When circle strafeing around a player, the Nuts & Bolts appear to slow right down or even stop moving. This is much easier to detect if crouched.
