JangaFX releases EmberGen 0.5.5
Friday, July 17, 2020 | Written by Jim Thacker
JangaFX has released EmberGen 0.5.5, the latest beta of the real-time tool for simulating gaseous liquids.
The version extends the software by a GPU particle system in progress, with which finer details can be generated in smoke and fire simulations than in the existing voxel-based simulation.
In related news, Otoy has released EmberGenFX, its version of EmberGen for OctaneRender users, as a free public beta for artists with paid OctaneRender subscriptions.
A promising hardware-independent real-time simulator for gaseous liquids
EmnberGen is described by JangaFX as "the fastest platform for simulating volumetric liquids in the world" and promises users the opportunity to create smoke and fire effects with a complexity that comes close to that of offline tools like FumeFX.
The EmberGen combustion system not only simply reproduces the dynamics of gaseous liquids, but also mimics how real fireballs consume fuel and oxygen.
Simulations can also be influenced by wind forces and turbulence and limited by collisions with the base plane and external borders.
The resulting data can be exported to other DCC applications in OpenVDB format or rendered directly in EmberGen as flipbook image sequences for use in game engines such as Unity and UE4.
Images can be exported in a number of standard 2D formats, including EXR, TGA, and PNG, along with motion vectors, normal maps, and additional data such as emission, albedo, and temperature values.
The software is GPU independent and has relatively low minimum hardware requirements: an Nvidia GeForce GTX 1060 or an AMD equivalent.
New in 0.5.5: support for "millions of GPU particles"
To do this, EmberGen 0.5.5 adds a new GPU particle mode, which should produce finer, more detailed details than the voxel-based standard simulation.
It is not a basic particle simulation – the particles are forwarded based on the underlying simulation data – but they can be rendered independently of the volume simulation or together with it in a hydride mode.
The particle system is still under construction and can currently only be used to render image sequences: JangaFX states that it is working on the option to export particle data in Alembic format.
New simulation presets, improved workflow, option to stop rendering
The update also introduces 19 new simulation presets, many of which use the new GPU particle system, and improves the workflow in the node diagram and timeline.
Users can now pause a simulation once all export image nodes have been processed. While support for "simple tiled rendering" should mean that "long rendering blocks the user interface less".
Pricing and system requirements
EmberGen is only available for Windows 7+. It is still officially in beta.
Indie subscriptions for artists with sales of less than $ 1 million a year cost $ 24.99 a month or $ 239.99 a year. Users can qualify for a perpetual license after 12 months of consecutive payments.
Studio subscriptions for studios with sales of up to $ 100 million per year are now $ 149.99 per month or $ 1,399.99 per year per nodelocked license and $ 239.99 per month or 2,299 $ 99 per year per floating license.
Anyone with an active OctaneRender subscription can use EmberGenFX free of charge during the public beta, even for commercial work. After that, it becomes a commercial subscription.
