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.
