2D flame with rising turbulence
In your harnessGodot shaderMIT
Draw a flickering flame in a rectangle: distorted fractal noise rising over time, shaped by a tapering mask, coloured through a four-step heat ramp with transparency outside the flame.
What it takes and gives
- Shader type
- canvas_item
- Parameters
- core_color (vec4 = 1, 0.97, 0.75, 1), inner_color (vec4 = 1, 0.75, 0.2, 1), outer_color (vec4 = 0.95, 0.3, 0.05, 1), smoke_color (vec4 = 0.3, 0.05, 0.02, 1), rise_speed (float = 1.8), turbulence (float = 0.4), base_width (float = 0.5), height (float = 0.85) and 1 more
- Use it on
- A ColorRect (or any CanvasItem) sized to the area to fill; UVs span 0 to 1 across it.
- Result
- A tall flickering flame with a pale core, yellow and orange body and dark red tips.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement

Limits. Flat 2D effect with no light emission; add a PointLight2D to light the scene. The shape is symmetric on average, so very wide flames look like a column.
