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.

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.

Bugs

• The Nuts & Bolts particle effect has a visual problem. When circle strafing around a player, the Nuts & Bolts appear to slow right down or even stop moving. This is much easier to detect if crouched.
• On certain graphics drivers, particles no longer appear to have a distinct bright glow. This applies on the medibeam, unusual effects and energy based weapons. It has also has been reported by DirectX 11 users.
• Upon death or disconnect, particle effects often stay in the spot the player was, fully animated.

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
