Radial Burst
Radial Burst is a procedural ShaderWeave generator: describe the look in JSON, choose a seed, and render png, webp, css. It runs in the browser editor and through the rendering API, so a recipe you tune by hand can be reused in a build step or by a coding agent.

What it gives you.
- Deterministic output — the same recipe, seed and engine version produce byte-identical pixels.
- Exports png, webp, css from one recipe.
- Available in the editor, the REST API, the MCP server and the CLI.
- Tune colors, rays, twist, centerX, centerY, softness and more with schema-driven controls.
Parameters.
Radial Burst exposes these parameters. Every value is validated against the generator’s published JSON schema before a render starts.
- colors
- rays
- twist
- centerX
- centerY
- softness
- background
Formats and credit cost.
- png
- webp
- css
Still images cost one credit per output megapixel. Animation costs ten credits per megapixel per second. SVG and CSS output costs one credit.
| Example output | Credits |
|---|---|
| Full HD image · PNG | 3 |
| Full HD image · WebP | 3 |

Where it works.
Hero and section backgrounds
Drop a full-bleed backdrop behind product copy, then regenerate the same art at any size without re-drawing it.
Brand-locked variants
Swap palette parameters to keep every campaign asset inside the same visual system, seeded so each version stays reproducible.
Automated pipelines
Request the recipe from a build step or an agent so landing pages ship with matching art on every release.
Questions.
- How many credits does a Radial Burst render cost?
- Stills cost one credit per output megapixel and animations cost ten credits per megapixel per second. Full HD image · PNG is 3 credits; Full HD image · WebP is 3 credits.
- Can I use Radial Burst output commercially?
- Yes, on a paid plan. Free-plan exports are for evaluation and non-commercial use, and the free plan does not include API access.
- Can I call Radial Burst from an API or a coding agent?
- Yes. POST /v1/generate/radial-burst with a bearer API key renders synchronously, POST /v1/jobs queues an animation, and the MCP server exposes the same generator to coding agents. API access requires a paid plan.
- Is Radial Burst output reproducible?
- Yes. A render is a pure function of the generator, its parameters, the seed and the engine version, so re-running the same recipe returns the same image later.
