Rain Sizzle (unstable=3)

Introduction

The Rain Sizzle effect (unstable=3) flips the unstable concept upside down. Instead of injecting bright sparks into a cooling blade, it constantly drives the blade toward full brightness while random dark dents punch through the surface.

The result looks like a hot, energized blade being struck by invisible droplets. It stays more solid and readable than most unstable effects, which makes it a great choice when you want visible instability without losing the feeling of a powered blade.

How Rain Sizzle Works

Rain Sizzle uses a simplified two-step simulation with no drift step.

1. Heat up — every pixel gains heat each frame. The amount is random between lcool and hcool.
2. Dent — with a probability controlled by sparkf, multiple random positions on the blade lose a large amount of heat, creating dark dents.

Those dents do not travel. They stay where they appear and fill back in as the blade keeps heating. That is what gives Rain Sizzle its static sizzling look.

Core Parameters

hcool — Heating Rate High

Default: 70

In Rain Sizzle, this controls the maximum amount of heat added per frame. Higher values make the blade recover from dents faster.

lcool — Heating Rate Low

Default: 20

This is the minimum heat added per frame. The gap between lcool and hcool determines how uneven the recovery looks across the blade.

sparkf — Dent Probability

Default: 120

This controls how often new dents appear. Higher values mean more frequent dark interruptions.

sparkd — Dent Density

Default: 10

This defines what percentage of the blade can receive dents when a dent event occurs. Multiple dents appear at random positions across the blade.

Note: Like Classic Unstable, Rain Sizzle still guarantees at least one dent per event.

Drift Mode

drift — Not Used

Rain Sizzle has no drift step. The drift parameter does nothing for this effect. Dents appear in place and heal in place.

That is deliberate. Adding drift would smear the dents and ruin the sharp raindrop-like character.

Audio Reactivity

mapping_unstable — Reactivity Source

Default: 1

mapping_unstable=0 — None

The effect stays fixed. Dent frequency and recovery rate do not respond to sound.

mapping_unstable=1 — Audio

Rain Sizzle reacts to sound volume.

• Louder sounds increase denting and slow the recovery, so the blade becomes more disrupted
• Quieter moments let the blade settle and stay more solid

That makes the blade feel more damaged or disturbed during swings and clashes. Use mapping_audio=low,high to tune the response range.

Note: Audio is the main reactivity mode for Rain Sizzle. Angular and motion mapping are not the primary implementation path for this effect.

Color Controls

Rain Sizzle uses the same general color mapping system as the other unstable effects.

ecolor — Effect Color

This is the color used in the hot and bright parts of the blade. Since Rain Sizzle keeps the blade mostly hot, this color often dominates the overall look.

ecolor=1023,400,0,0     # orange
ecolor=0,1023,400,0     # toxic green
ecolor=1023,200,0,0     # molten red-orange
ecolor=1023,1023,1023,0 # bright white

On CFX, color channel values can go up to 1023.

mapping_color — Color Mapping Mode

For Rain Sizzle, Legacy mode often works best. Because the blade spends most of its time bright, Heat Map mode can wash the blade toward white or yellow too easily. Legacy mode gives cleaner two-tone contrast.

mapc — Color Mapping Strength

Default: 50

This controls how strongly the heat affects visible color.

mapb — Brightness Mapping Strength

Default: 50

This controls how strongly heat affects brightness.

Tip: For Rain Sizzle, mapb is one of the most important controls. Since the blade is mostly bright, mapb decides how deep and noticeable the dents really are.

Refresh Rate

refreshfx — Effect Refresh Interval

Default: 12 ms

Because Rain Sizzle adds heat every frame, the refresh rate directly changes how fast dents recover and how fast the whole sizzle pattern feels.

Tip: Slower refresh means less total heat added per second, so dents become more visible. If you slow the refresh down a lot, you may want to raise hcool to compensate.

Quick Reference Card

Tuning Tips

1. mapb is your main visibility control. It decides how deep the dents look.
2. Recovery speed depends on both hcool and refresh rate. If dents heal too fast, either lower hcool or slow down refreshfx.
3. Legacy mode often looks better than Heat Map. It gives clearer contrast between the bright blade and the dented spots.
4. Low density plus high probability gives frequent isolated dents. High density plus lower probability gives larger, heavier disruptions.
5. Audio reactivity makes the blade feel more damaged during action. During loud moments, the blade becomes more disrupted and takes longer to recover.
6. Think of Rain Sizzle as a brightness texture layer. It works especially well when you want a blade that stays readable but still feels unstable.
