EmberGen
EmberGen is JangaFX's real-time volumetric simulation tool for fire, smoke and explosions. It runs entirely on the GPU, which means you see your simulation rendering live as you sculpt it, instead of waiting through long offline bakes. Game VFX artists love it because it turns days of iteration into minutes, and it exports flipbooks and VDBs that drop straight into Unreal, Unity and other pipelines.

What is EmberGen?
EmberGen is a real-time volumetric fluid simulation application built by JangaFX, a studio founded by game industry VFX veterans. Where traditional tools simulate fire and smoke on the CPU and take minutes or hours to bake, EmberGen runs the whole simulation on your GPU and renders it live, so you see the fire flicker and the smoke billow while you are still dragging sliders.
It is purpose-built for a very specific job: making beautiful, controllable fire, smoke and explosion effects fast. Game artists use it to generate flipbook sequences that play inside Unreal or Unity as sprite sheets, and film and motion designers use it for stylized simulation shots and even for faster iteration on look development.
The workflow is simple compared with a full DOP solver. You drop in an emitter, shape it with a few sliders, let the simulation play, and tweak until it looks right. That immediacy is the entire point of the tool, and it is what has made EmberGen popular across studios of every size.
Key Features
- Fully real-time GPU simulation and rendering of fire, smoke and explosions
- Flipbook export with custom frame counts for Unreal, Unity and Godot
- VDB export for use in Houdini, Blender and other DCC tools
- Wind fields, turbulence and curl noise for natural motion
- Timeline-based simulation with scrubbing and looping
- Layered emitters and materials for complex looks
- Built-in presets to get started quickly
- GPU-accelerated so a single workstation handles complex scenes
How to get started
Download the free trial from the JangaFX website; it is fully functional so you can decide whether the tool fits your pipeline before paying. The interface is centered around emitters and a timeline, and most first projects start from one of the built-in fire or smoke presets.
From there you tweak temperature, density and turbulence, then export. If you are working in a game engine, the flipbook exporter handles the heavy lifting: pick your resolution and frame count, and EmberGen writes out the sequence ready for Niagara or VFX Graph.
- Download and install the free trial from jangafx.com
- Open a preset like fire or explosion from the library
- Adjust emitter shape, fuel and turbulence until it looks right
- Preview at full speed to check the motion
- Export a flipbook or VDB for your game engine or DCC tool
Use cases
- Game VFX: explosions, fire abilities and smoke for characters and environments
- Flipbook sequences for Unreal Engine Niagara and Unity VFX Graph
- Stylized simulation shots for cinematics and trailers
- Fast look development before a final Houdini sim
- VDB volumes for compositing and offline renders
- Motion graphics and music video effects
Pricing and licensing
EmberGen is sold as a perpetual license, meaning you pay once and own the version you bought, with optional annual maintenance that covers updates. This is a deliberate contrast to the subscription model many creative tools have moved to, and it has made EmberGen popular with freelancers.
JangaFX also offers a free trial so you can evaluate the tool, and student discounts have been available in the past. Exact pricing changes, so check the official website for current numbers.
Pros and cons
The killer feature is iteration speed. Seeing a fire sim render in real time means you can try twenty variations in an afternoon, something that would take days with offline solvers. The flipbook and VDB export paths are clean, the interface is approachable, and the perpetual license is refreshingly simple.
The trade-off is scope. EmberGen is laser-focused on volumetrics, so it will not replace a full DCC for geometry, shading or general VFX. It is currently Windows-only, and heavy scenes still demand a serious GPU to stay interactive.
