🪄 Magic / Spell FX – Procedural VFX Generator for Aseprite

Magic / Spell FX Generator is a procedural VFX generator for Aseprite, designed specifically for pixel art.

Create magic circles, sigils, runes, energy auras, spell casts, elemental bolts, novas, portals, and wisps — directly inside Aseprite.

No source sprite needed: every mote is a generated shape colored from a ramp, or a rotating hue for prismatic arcana.

Instead of manually drawing every frame, build your spell effect from multiple procedural layers and let the plugin generate the animation for you.

Each effect is constructed from up to six independent layers:

🔯 Sigil ✨ Flare 🌊 Nova 💫 Motes 🌫️ Mist ⚡ Arc

Every layer has its own timing, behavior, colors, and parameters, allowing you to create complex spell effects while keeping full control over the final animation.

The result is baked directly into real Aseprite frames, ready to edit, export, and use in your game.

Every effect is generated by the same deterministic seeded engine that powers Impact / Explosion FX and Particle System 2D — same seed + same settings always reproduce the exact same result, frame for frame.

✨ Key Features

🔯 6-Layer Procedural VFX System

Build effects by combining up to six independent procedural layers:

• 🔯 Sigil — a real procedural magic circle with concentric rings, an N-point star polygon (pentagram, hexagram, heptagram, and beyond), radial tick marks, and orbiting node dots. The sigil can draw itself on, hold, spin, and fade, or spin continuously in Loop mode
• ✨ Flare — irregular explosive flash generated procedurally, with Sparkle, Star, Rays, and Bloom styles
• 🌊 Nova — expanding ring that grows and becomes thinner, with an optional second ring
• 💫 Motes — burst particles with 11 procedural glyph shapes
• 🌫️ Mist — large particles that grow and fade over time
• ⚡ Arc — procedural branching lightning effect

• Each layer has its own start delay and duration, allowing you to create detailed multi-stage spell effects.
• You can enable or disable individual layers at any time.

• Color ramps (3-stop, start/mid/end)
• Fading dotted mote trails for comet / wisp effects
• Twinkle — per-mote opacity shimmer for star-field sparkle
• Prismatic — hue rotates over a mote's lifetime instead of using a fixed color ramp

• Motes can converge toward the center, spiral in or out, or wander in an ambient drift.
• Perfect for:

• 🌀 Teleportation
• 🕳️ Energy absorption
• ✨ Buffs
• 🧚 Wisps
• 🌌 Ambient magic
• 🔮 Spell casts

🌊 Dynamic Novas

• Generate expanding energy rings procedurally.

• Start delay
• Color
• Optional second nova ring with its own delay and radius

Perfect for:

• Sparkle
• Star
• Rays
• Bloom

Control:

• Number of spikes
• Inner radius
• Maximum radius

• Control:

• Bolt length
• Number of segments
• Displacement
• Branch probability
• Duration
• Color
• Direction

The lightning is built with recursive midpoint-displacement and uses its own independent deterministic random stream, keeping bolt flicker separate from the rest of the simulation.

Perfect for:

• ⚡ Lightning conjures
• 🔮 Arcane missiles
• 🌩️ Storm rings
• ⚡ Elemental strikes
• 💠 Energy attacks

🌫️ Procedural Mist

• Create secondary mist automatically after a cast, ritual, or magical impact.

• Size
• Speed
• Gravity
• Drag
• Lifetime
• Scale curve — Constant, Shrink, Grow, Grow-Shrink

Mist particles can grow and fade naturally, making them ideal for:

• ☠️ Necrotic blasts
• 🟢 Cursed fog
• 🕳️ Void pulls
• 🌫️ Lingering spell effects
• 🔮 Ritual magic

🎨 Color Palettes

• Customize the entire visual style of your spell.
• Each layer can use its own color ramp.
• Included ready-made elemental palettes:

• 🔥 Fire
• 🧊 Ice
• ⚡ Storm
• ☠️ Poison
• ✨ Holy
• 🟣 Shadow
• 🟡 Arcane
• 🌿 Nature
• 💧 Water
• 💀 Necrotic

• One click recolors Sigil, Flare, Nova, Motes, Mist, and Arc together.
• You can also create your own custom colors.

🌪️ Advanced Forces

• Add more organic movement to your effects with procedural forces.
• Turbulence — Adds procedural, adjustable-frequency jitter to Motes and Mist.

Vortex — Creates a spiral / tangential force, useful for teleportation, magical implosions, energy absorption, and swirling motes.

These forces can be combined with the normal physics simulation.

🎯 Directional Effects & Area Control

• Control exactly where motes are emitted.
• Set:

• Direction angle
• Spread
• Global effect angle
• Global rotation
• Origin offset
• Emission arc

The emission arc can also clip Flare, Nova, and Arc into a dome, making it easy to create casts and blessings that fan out from above instead of spraying in every direction.

🪞 Perspective Flatten

• Squash any layer on the Y axis around the origin so a circle reads as a ground ellipse.
• This is ideal for isometric or top-down spells.
• Each layer opts in independently, so a Sigil can hug the floor while its Motes remain perfectly round.

🎚️ Global Size & Speed Controls

• Quickly adjust the entire spell without manually changing every layer.
• Global Size — Scales the effect's dimensions, radius, mote travel, and other spatial properties.
• Global Speed — Changes mote movement speed while keeping the layer timing intact.
• This makes it much faster to create small, fast spells or large, slow magical effects from the same base preset.

👁️ Real-Time Preview

• Preview your spell before generating the final animation.
• Controls include:

• ️ Play
• ⏸️ Pause
• 🔁 Play Once or Loop preview modes
• Mouse-wheel zoom
• Drag-to-pan
• Live particle count
• Frame statistics

The preview makes it easy to tune timing, scale, mote count, colors, and movement before baking the result into your sprite.

🎬 Flexible Animation Output

• Control exactly how the generated animation is created.
• Choose:

• Total frame count
• Simulation FPS
• Output width and height (up to 512×512)
• Fit to Frames
• Custom output layer name
• Separate layer output

Fit to Frames — Automatically remaps the complete effect so it fills exactly the number of frames you specify.

Separate Layers — Bake Sigil, Flare, Nova, Motes, Mist, and Arc into their own individual Aseprite layers instead of one merged layer. This makes it easy to continue editing individual parts of the spell after generation.

🎲 Deterministic Generation

• Every spell uses a seeded random system.
• Same seed + same settings = identical result.
• This makes it easy to reproduce a spell exactly, experiment with variations, and keep your animations consistent.

➕ Combine Presets

• Use Add Mode to build more complex spells by combining different presets.
• For example:
• Sigil + Nova + Mist
• or
• Motes + Arc + Flare
• This allows you to use existing presets as building blocks instead of creating every spell from zero.

💾 Save & Load Your Settings

• Save your favorite configurations to disk and reload them anytime, on top of the 50+ built-in spell presets.
• Use your own custom settings as a starting point for future spells instead of rebuilding your workflow every time.

🎨 Designed for Pixel Art

Magic / Spell FX Generator is designed around procedural rasterized shapes and frame-based animation rather than smooth vector effects.

You get actual pixel-art frames that you can continue editing manually after generation.

No external VFX software required.

Pairs naturally with Impact / Explosion FX and Particle System 2D:

Use Particle System 2D for looping ambient effects, Impact / Explosion FX for punchy one-shot hits, and Magic / Spell FX for spellcasting and magical VFX.

All three share the same deterministic engine, so they behave consistently together.

✅ Compatibility

Requires Aseprite with Lua scripting support.

Latest stable version of Aseprite is recommended.
