// Burn Effect with Ashes - Windows burn with 8 random ember colors, floating ash, and glowing sparks
|
|
//
|
|
// Adjustable parameters:
|
|
// - uv * 8.0: Edge roughness - higher = finer burn pattern
|
|
// - threshold * 0.8: Burn reach - how far burn extends into window
|
|
// - 0.08: Glow width - width of ember glow line
|
|
// - 150.0 in ash_particle: Ash size - higher = smaller particles
|
|
// - 280.0 in ember_spark: Spark size - higher = smaller sparks
|
|
// - Loop counts (7.0, 8.0): Particle layers - more = more particles (performance impact)
