Muzzle-flash effect: a one-shot ~80 ms burst at a gun barrel, from particles or a star-burst quad.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# muzzle-flash — One-Shot Star-Burst Flare
A muzzle flash is on screen for 60–100 ms. Long enough to read, too short to animate. The recipe: a single billboarded quad with a star-burst gradient shader, fired by `restart()` on a weapon's `fired` signal, plus an `OmniLight3D` snapping on for 60 ms to light the room. Optional: a tiny GPUParticles3D one-shot for sparks. Most shooters use this pattern.
## When to use
- "Add a muzzle flash to the rifle / pistol / shotgun."
- "When I fire, the gun should flash."
- "Spell-cast burst at the wizard's palm." (one-shot at hand position)
- "Cannon fires, big flash at the barrel."
- The user just hooked up a weapon and the firing reads as silent / weightless.
## When NOT to use
- The user wants a *continuous* flame (flamethrower) — use `vfx-fire`, not muzzle-flash.
- The user wants the impact spark on the wall the bullet hit — that's `vfx-hit-spark`.
- The user wants a tracer line from barrel to target — use an `ImmediateMesh`
recipe, not this. The current Summer build has no `Line3D`
(`ClassDB.class_exists("Line3D")` is `false`).

How to install
mdr add summerengine/summer/vfx-muzzle-flash@sha256:a9d62c07a1806d19The line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
