PyroMetal
Real-time simulation
A GPU fluid solver with a physically-based combustion model. Inject fuel, ignite it, and watch fire, heat and smoke separate the way they do in the real world.
Real-time VFX · Native to Mac
Fire, smoke and explosions. In real time. On your Mac.
PyroMetal is a GPU-accelerated fire and smoke studio built for Apple Silicon. Design volumetric effects live at full speed, then export production-ready output for film and games.
Requires an Apple Silicon Mac. Free to create — a one-time unlock adds export.
What it does
A full simulator, running live on your GPU
Everything you need to design, simulate, light and render volumetric effects — interactively, without leaving the app.
Millions of particles
A GPU particle system holding up to a million sparks and embers, with real smoke and fire trails, bursts and firework-style stars — tuned per emitter.
Cinematic rendering
Volumetric ray-marching with blackbody fire, HDR bloom and filmic tonemapping, plus a full color-grade and post-effects suite built right in.
Scene tools
Emitters in sphere, box, cylinder, mesh or image shapes, force fields, effectors, colliders and up to eight self-shadowing lights.
Keyframe & scrub
Animate any parameter with a curve editor, then bake the simulation once and scrub the timeline back and forth instantly.
Export anywhere
MP4 video, PNG sequences, game-ready sprite sheets and VDB volumes for Blender and Houdini — across 12 render channels, up to 8K.
Showcase
From a single spark to a full explosion
Fireworks, muzzle flashes, colored smoke, volcanic plumes — art-directed in real time.
Flames
A physically-based combustion model, burning in real time.
Simulation with particles
Up to a million sparks and embers, coupled to the fluid.
Volumetric smoke
Dense, self-shadowing smoke with per-source color.
Real-time post effects
Grade and stylize the render as you work.

Where it's going
Roadmap
PyroMetal is actively developed. Here's what's being worked on — quality first, so we don't promise dates.
In development
- Alembic (.abc) animated mesh support — simulate against baked geometry caches
- Animated FBX import — emitters and colliders driven by skeletal and transform animation
- Stability and performance improvements across the solver
Planned
- OpenEXR image-sequence export (16-bit float, linear) for compositing pipelines
- Deeper collider interaction for particles — friction-aware sliding and rest states
- Expanded example library and one-click effect presets
- More force-field falloff shapes and controls
Exploring
- Direct engine-preset bundles for Unreal and Unity flipbook materials
- Additional interface languages
- Community preset sharing
The roadmap reflects current direction and may change as development progresses.
Known issues
Being investigated for upcoming updates.
- Shadow rendering artifacts — self-shadowing can show banding or patchy darkening in some scenes, most visibly with multiple lights or very dense smoke.
- Particle motion irregularities — particles can occasionally move unnaturally in certain setups, such as jitter or drift that doesn't follow the flow.
Simple, honest pricing
Free to create. Pay once to export.
Design, simulate, light and preview as much as you like at no cost.
- Full simulation, rendering and animation — free.
- A single one-time purchase unlocks all export formats and channels.
- No subscription. Yours forever.
