What ForgeFX does
Multi-layer emitters
Burst and continuous emitters with deterministic seeds. Spawn from points, circles, rings, boxes, lines and cones.
Physics
Gravity, drag, radial and tangential forces, swirl and deterministic turbulence.
Shapes & curves
17 procedural particle shapes and draggable curves for size, opacity and speed over a particle's life.
Color control
Unlimited color stops per particle lifetime, palettes, ordered dithering, glow and outline.
True pixel output
Nearest-neighbour rendering with 16×16, 32×32, 64×64 and 128×128 output presets.
Presets
15 Fire and Magic presets plus a constrained random generator to start from.
From idea to spritesheet
- Open ForgeFX from Pixforge and pick a preset, or start from scratch.
- Tweak the emitters: shape, forces, colors and timing, with playback, scrubbing and frame stepping.
- Choose the output size and palette so the effect matches your game's art style.
- Export a PNG spritesheet, a PNG plus JSON atlas, zipped PNG frames, a GIF or a WebM video.
Made for game developers
- Spritesheets and atlases load in any engine that reads images, such as Godot, Unity or GameMaker.
- Export trims empty trailing frames and arranges frames into a compact grid.
- Projects save as versioned JSON, with undo / redo and local autosave.
- Runs entirely in your browser, with no signup.
