Why we like it

MotionFlow earns its place for providing motion vector passes independently of Blender's render passes, with technology inspired by a research paper published by Walt Disney Animation Studios.

What is Motionflow?

MotionFlow is a Blender add-on that adds depth and weight to animation by behaving like a stylized contact shadow and edge separation system, giving objects perceived depth and form. Its technology is inspired by a research paper published by Walt Disney Animation Studios.

The add-on supports all major animated object types — Meshes, Armatures, Curves, and Empties — and stores motion data frame-by-frame with a clean folder structure. A simple UI runs in the Sidebar, with one-click Compositor Nodes setup. The Motion Smears feature applies adjustable outline smearing that smears an object's Grease Pencil outline so they bleed into the background, with an adjustable sample count for precision. It provides clean, customizable motion vector passes independently of Blender's render passes.

Version 1.3 adds a heavily optimized Convex Hull that decreases render time, and includes documentation and a video tutorial. MotionFlow works with Blender 3.6 to 5.0 and the Cycles, Eevee, and Freestyle render engines.

Who is Motionflow best for?

Motionflow is best for nPR (Non-Photorealistic Rendering) and advanced compositing workflows that need motion vector EXRs and smeared outlines for animated objects and rigged meshes.

How much does Motionflow cost?

Motionflow is completely free to download and use.

The add-on runs from Blender's Sidebar and offers a one-click Compositor Nodes setup. Documentation and a video tutorial are included to help you get started, and version 1.3 adds a heavily optimized Convex Hull that decreases render time.

Which render engines does MotionFlow support?

MotionFlow supports the Cycles, Eevee, and Freestyle render engines in Blender. It generates clean, customizable motion vector passes independently of Blender's own render passes, and it can output motion vector EXRs for animated scenes. The add-on supports all major animated object types, including Meshes, Armatures, Curves, and Empties, and stores motion data frame-by-frame with a clean folder structure. Version 1.3 also includes a heavily optimized Convex Hull that decreases render time.

What object types can MotionFlow handle in Blender?

MotionFlow supports all major animated object types in Blender, including Meshes, Armatures, Curves, and Empties. It stores motion data frame-by-frame with a clean folder structure and offers an adjustable sample count for precision. The Motion Smears feature applies adjustable outline smearing that smears an object's Grease Pencil outline so they bleed into the background. A demo video is available, and version 1.3 includes documentation and a video tutorial for reference.

Is MotionFlow free to use?

MotionFlow is listed as free in this catalog. For current licensing terms, check the developer's page, since the add-on is distributed under the GPL license.
