A practical guide to the Unstable Fire effect on Crystal Focus X, including dual-layer fire behavior, overlay toggle, spark spread, and audio-reactive unstable flame setups.
lcool, hcool, spark, sparkddriftmapb, mapc, fxmapUnstable Fire combines two independent fire layers into one effect. The base layer is always an emitter-fed fire drifting upward. An optional overlay layer can add random sparks across the full blade for a much wilder unstable look.
| Layer | Always active? | Behavior |
|---|---|---|
| Base fire | Yes | Emitter-generated fire that drifts upward from the bottom of the blade |
| Unstable overlay | Only with drift=1 | Random sparks scattered across the full blade |
| Parameter | Role in Unstable Fire |
|---|---|
unstable | Set to 15 to select the effect |
lcool | Cooling amount and base-fire heat floor |
hcool | Cooling ceiling and base-fire heat ceiling |
spark | Spark intensity and burst behavior |
sparkd | Spark spread and base-burst size |
drift | Overlay toggle: 0 off, 1 on |
mapb | Brightness mapping |
mapc | Color mapping |
fxmap | Mapping mode: 0 none, 1 audio |
When drift=1, the overlay cools, drifts upward, and injects random sparks across the entire blade.
The base fire always runs. It drifts upward and writes bursts of heat at the emitter zone.
Both layers are rendered separately, which lets the base fire and scattered overlay coexist visually.
With fxmap=1, cooling is reduced and spark intensity is boosted with volume, so the whole blade feels more reactive and aggressive.
A clean upward fire from the emitter only.

fxmap=1drift is your mode switch. Off gives base fire only, on adds the unstable overlay.spark means fewer but more intense bursts.sparkd makes both the overlay spread and base bursts larger.
