EmissiveFX

Animated emissive (self-illumination) effects for GTFO weapons — plus a fully independent bullet tracer with an in-game color picker.

20 emissive modes · tracer from muzzle to impact point · floating 14-color panel · direct #RRGGBB input · no gameplay code patched.

Features

Bullet tracer (independent, off by default)

• Draws a thin glowing energy beam from the muzzle to the impact point, fading out over ~1.5 s
• 14 preset colors via a floating panel, or type any #RRGGBB value directly in-game
• Local player only; fully independent from every other option on the page

Emissive weapon effects (20 modes)

• Solid · Breathing · Alarm · Flicker · Charge · Hue flow
• Twinkle · Sparks · Noise · Anti-phase
• Sweep · Chase · Gradient · Rainbow
• Heat · Cold · Ember
• Heartbeat · Low-health warning

Scan policy — the renderer scan is the only source of stutter. Pick "Scan off" for zero stutter (effects stay visible, they just stop updating).

Installation

Recommended: install through r2modman / Thunderstore Mod Manager — it installs BepInExPack_GTFO automatically.

Manual:

1. Install BepInEx (IL2CPP) for GTFO
2. Drop EmissiveFX.dll into <Game>\BepInEx\plugins\
3. Launch the game

Usage

In game: Settings → 效果 (Effects)

While the color panel is open you can nudge it with the arrow keys (position is saved automatically).

Configuration

BepInEx\config\gtfoskin.emissivefx.cfg → [Trajectory]

Notes

• Emissive effects are only visible inside a level while holding a weapon — not in the lobby.
• The tracer is off by default; enable it on the Effects page.
• Only your own tracer is drawn (teammates' tracers are not shown).
• Nothing in the game's gameplay code is patched: the tracer polls a read-only field and casts its own ray, so it cannot crash the game.

Changelog

v1.0.1

• Fixed: the emissive override now merges with the renderer's existing property block instead of replacing it, so weapon-inspection views and other per-renderer effects are no longer disturbed
• README: the intro now states up front that this is a SKINS-format skin emissive-material mod
• README: added a How-it-works section explaining the emissive material approach (_EmissiveColor + MaterialPropertyBlock, _EmissiveMap only, SKINS compatible)

1.0.0
