What is HOROPTR Diffusion Glow?

HOROPTR Diffusion Glow is a GPU-accelerated glow plugin for DaVinci Resolve and Fusion Studio. It's built to shape luminous detail with speed, control, and instant feedback, and the effect stays resolution independent as you work.

The plugin handles both pixel and spectral dispersion, and you can color the glow from core to edge. Three decay modes cover different looks. GPU acceleration runs through CUDA on Windows and Metal on macOS, keeping the processing on your graphics hardware across both platforms.

Diffusion Glow supports DaVinci Resolve versions 21, 20, 19, 18, 17, and 16, covering current and older installs alike. It earns its place in the toolfarm library as a focused glow plugin that pairs responsive, GPU-driven feedback with fine control over how the glow disperses and colors.

Who is HOROPTR Diffusion Glow best for?

HOROPTR Diffusion Glow is best for adding glow to footage in DaVinci Resolve and Fusion Studio, with control over dispersion, core-to-edge coloring, and decay.

How much does HOROPTR Diffusion Glow cost?

HOROPTR Diffusion Glow is completely free to download and use.

Frequently asked questions

Which DaVinci Resolve versions does HOROPTR Diffusion Glow support?

HOROPTR Diffusion Glow supports DaVinci Resolve versions 21, 20, 19, 18, 17, and 16. That range covers several generations of Resolve, from recent releases back to version 16, and the same versions are listed as its requirements. If you're running one of these versions of DaVinci Resolve, the plugin is built to work with your setup. For any release outside that list, or to confirm the exact build you need, check the developer's page before installing.

Does HOROPTR Diffusion Glow work on both Windows and macOS?

HOROPTR Diffusion Glow runs on both Windows and macOS, using different GPU backends on each. On Windows it accelerates through CUDA, and on macOS it uses Metal. Because the plugin is GPU-accelerated on both platforms, the glow processing runs on your graphics hardware rather than the CPU. If you work across a mixed Windows and Mac environment, the plugin covers both through these two backends. For specifics on hardware and setup, the developer's page is the place to confirm current details.

Does HOROPTR Diffusion Glow work in Fusion Studio as well as DaVinci Resolve?

HOROPTR Diffusion Glow works with Fusion Studio in addition to DaVinci Resolve. It's described as a glow plugin for both applications, so you can use it whether you're working inside Resolve or in Fusion Studio. The same core capabilities apply, including pixel and spectral dispersion, coloring the glow from core to edge, and three decay modes. For details on setup within Fusion Studio specifically, the developer's page is the place to confirm current support.

Is HOROPTR Diffusion Glow free?

HOROPTR Diffusion Glow is listed as free in this catalog. Licensing terms can change over time, so for the current arrangement and any details around how it's distributed, the developer's page is the best place to check. Beyond cost, the plugin is a GPU-accelerated glow tool for DaVinci Resolve and Fusion Studio, with pixel and spectral dispersion, core-to-edge glow coloring, and three decay modes.
