MeltFlow Blur is a GPU-accelerated plugin for After Effects that applies a melting-style blur centered around a point you specify in the composition. You define the blur area and can adjust its aspect ratio and rotation.
Beyond the core blur, the plugin includes five turbulence maps and supports animated turbulence. It also adds grain noise and a wind-driven blur direction, giving you several parameters to control the effect. GPU acceleration handles the processing.
Built by grape design, MeltFlow Blur runs on After Effects 2026, 2025, 2024, and 2023. It arrived at its initial version 1.0 in May 2026, and a demo video is available on the developer's page. It's listed here as free, and sits at popularity rank 450 on aescripts.
