Why we like it

Flux earns its place in the aescripts library for generating 3D volumetric fractal flames across both traditional and 360/VR formats. Support for the native After Effects 3D camera, a built-in camera in After Effects and Premiere Pro, and GPU-accelerated volumetric rendering make it a self-contained way to build nebula and sci-fi backgrounds.

What is Mettle Flux?

Mettle Flux is a plugin for Adobe After Effects and Premiere Pro that generates 3D volumetric fractal flames. It produces backgrounds, nebulas and sci-fi effects, with output in traditional video as well as 360/VR formats, covering monoscopic and stereoscopic over/under and side-by-side layouts.

Animations start from the FLUX Preset Panel, which applies presets in one click, and further presets are available through the FLUX Effects Control Panel in After Effects. A Globe Preview Panel lets you work on and view results in 360°. From there you can shape the output using Force Field, Mutations, Iterations, Evolutions, Lights and Symmetry controls.

Rendering is GPU-accelerated and volumetric. Flux supports the native After Effects 3D camera and includes a built-in camera for both After Effects and Premiere Pro. It runs in After Effects from CC 2015.3 through the 2026 release and in Premiere Pro from CC through 2023, with native Apple Silicon support and multi-frame rendering added in earlier updates.

Who is Mettle Flux best for?

Mettle Flux is best for creating volumetric fractal flame backgrounds, nebulas and sci-fi effects for traditional video or 360/VR projects in After Effects and Premiere Pro.

How much does Mettle Flux cost?

Mettle Flux is completely free to download and use.

Frequently asked questions

Which After Effects and Premiere Pro versions does Mettle Flux support?

Mettle Flux runs in After Effects from CC 2015.3 up to the 2026 release, covering the 2020 through 2025 versions along with CC 2017, CC 2018 and CC 2019 in between. For Premiere Pro it supports CC through 2023, including CC 2014, CC 2015, CC 2015.3, CC 2017, CC 2018, CC 2019 and the 2020 to 2023 releases. Version 1.16.3 is the current build. If you are on a newer release than those listed, check the developer's page to confirm compatibility before installing.

Can Mettle Flux output 360/VR footage?

Mettle Flux supports both traditional video and 360/VR formats. For VR it can render monoscopic output as well as stereoscopic over/under and side-by-side layouts. A dedicated Globe Preview Panel lets you work on and view results in 360° while you build them. The plugin also supports the native After Effects 3D camera and ships with a built-in camera that works in both After Effects and Premiere Pro, so you can move through the volumetric fractal flames it generates.

Does Mettle Flux use the GPU for rendering?

Mettle Flux uses GPU-accelerated, volumetric rendering to produce its 3D fractal flames. GPU-accelerated mode was added for both After Effects and Premiere Pro in an earlier update, and later releases brought native Apple Silicon support and multi-frame rendering. To shape the look, it exposes Force Field, Mutations, Iterations, Evolutions, Lights and Symmetry controls, and animations can be applied in one click from the FLUX Preset Panel, with more presets in the FLUX Effects Control Panel in After Effects.

Is Mettle Flux free to download?

Mettle Flux is listed as free in this catalog. Licensing terms can change, so check the developer's page on aescripts for the current details before you download. A demo video is available if you want to see more before installing. The current version is 1.16.3, released December 23, 2024, which added 2025 compatibility and resolved a licensing issue affecting Gmail accounts.
