Procedural lightning bolt with branches
In your harnessGodot shaderMIT
Draw a lightning strike: a jagged main bolt from top to bottom built from layered noise displacement, a branch splitting off, a wide glow, and a new random shape at every strike with flicker between strikes.
What it takes and gives
- Shader type
- canvas_item
- Parameters
- core_color (vec4 = 1, 1, 1, 1), glow_color (vec4 = 0.55, 0.6, 1, 1), jaggedness (float = 0.18), core_width (float = 0.006), glow_width (float = 0.08), strike_rate (float = 1.5), visible_share (float = 0.6), branch_amount (float = 0.6) and 2 more
- Use it on
- A ColorRect (or any CanvasItem) sized to the area to fill; UVs span 0 to 1 across it.
- Result
- A white jagged bolt with a blue glow running down the dark rectangle, with one side branch.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/lightning_bolt_2d/
Limits. Distance is measured horizontally, so near-horizontal bolts thin out; keep bolts mostly vertical or rotate the rectangle. One branch per strike.
