How to install

After Effects scripts & plugins

After Effects supports two main extension types: scripts (.jsx / .jsxbin) that appear in the File menu or the Window menu as panels, and plugins (.aex / .plugin) that show up as effects or generators.

Installing a script (.jsx / .jsxbin)

1. Quit After Effects.
2. Open the Scripts folder:
   • macOS: /Applications/Adobe After Effects [version]/Scripts/
   • Windows: C:\Program Files\Adobe\Adobe After Effects [version]\Support Files\Scripts\
3. To make the script open as a dockable panel, drop the file into theScriptUI Panels subfolder. Otherwise drop it directly into Scripts/.
4. Launch After Effects. In Preferences → Scripting & Expressions, enable Allow Scripts to Write Files and Access Network if the script needs it.
5. Find the script under Window (for panels) or File → Scripts.

Installing a plugin (.aex / .plugin)

1. Quit After Effects.
2. Copy the plugin file into the Plug-ins folder:
   • macOS: /Applications/Adobe After Effects [version]/Plug-ins/
   • Windows: C:\Program Files\Adobe\Adobe After Effects [version]\Support Files\Plug-ins\
3. Launch After Effects. The plugin will appear under the Effect menu or as a new generator, depending on its type.

Troubleshooting: if a script does not appear, confirm you placed it in the matching version's folder (After Effects keeps separate folders per major version), and that you have write permission to that location.

Browser extensions

Modulr ships some tools (like SiteBlock) as unpacked browser extensions. You install them in developer mode — no store listing required.

Chrome, Edge, Brave, Arc

1. Unzip the downloaded folder somewhere permanent (do not install from inside Downloads).
2. Open chrome://extensions (or edge://extensions, brave://extensions, arc://extensions).
3. Toggle Developer mode on (top right).
4. Click Load unpacked and select the unzipped folder.
5. Pin the extension from the puzzle-piece icon so it stays visible in the toolbar.

Firefox

1. Open about:debugging#/runtime/this-firefox.
2. Click Load Temporary Add-on…
3. Select the manifest.json inside the unzipped folder.

Note: temporary add-ons are cleared when Firefox restarts. For a permanent install, use a signed.xpi if provided.

Troubleshooting: if the extension disappears after a browser update, return to the extensions page and click Reload. Don't delete the unzipped folder — the browser loads the extension from that path each time.

Blender add-ons

Blender add-ons are distributed as .zip files (or single .py files). You install them from inside Blender's Preferences.

Install from a .zip

1. Keep the add-on zipped — don't unzip it first.
2. Open Blender and go to Edit → Preferences → Add-ons.
3. Click Install… (Blender 4.2+: use the dropdown in the top-right and pick Install from Disk).
4. Browse to the .zip and confirm.
5. Tick the checkbox next to the add-on in the list to enable it.
6. Click the hamburger menu and choose Save Preferences so it persists across sessions.

Where the add-on appears

Most add-ons add a panel to the N-panel in the 3D Viewport (press N to toggle). Some live under Edit, Object, or the File menu — the add-on's description in Preferences tells you where to look.

Troubleshooting: if the add-on fails to enable, open Window → Toggle System Console (Windows) or launch Blender from a terminal (macOS / Linux) to see the Python error. The most common cause is a Blender version mismatch — check the add-on's supported versions.
