v0.1.0

Easing, springs, and motion tools for After Effects, plus one-click import from Figma, Illustrator and Photoshop. Free and open source under the MIT license.

Install

1. Download the .zxp for your OS below:

   • macOS: rebound_0.1.0_macos.zxp
   • Windows: rebound_0.1.0_windows.zxp

   Grab the one that matches your machine. A ZXP signed on the other OS installs but shows a blank panel (a known Adobe signing quirk).

2. Install it with a ZXP installer such as the free ZXPInstaller. If it asks, install for the current user, not all users.

3. Fully quit and reopen After Effects (quit the app, not just the panel), then open Window > Extensions > Rebound.

Installer did nothing? Install it manually

A .zxp is a signed zip, so extracting it into the extensions folder is a valid install by itself. This always works when an installer silently fails.

macOS

D=~/Library/Application\ Support/Adobe/CEP/extensions/com.meszmate.rebound
rm -rf "$D" && mkdir -p "$D"
unzip -o ~/Downloads/rebound_0.1.0_macos.zxp -d "$D"

Windows (PowerShell)

$D = "$env:APPDATA\Adobe\CEP\extensions\com.meszmate.rebound"
Remove-Item -Recurse -Force $D -ErrorAction SilentlyContinue
Expand-Archive "$HOME\Downloads\rebound_0.1.0_windows.zxp" -DestinationPath $D

Then quit and reopen After Effects.

Still blank or missing?

• Wrong OS file. Use _macos on macOS, _windows on Windows.
• macOS quarantine. xattr -cr ~/Library/Application\ Support/Adobe/CEP/extensions/com.meszmate.rebound, then restart AE.

Full troubleshooting: docs/INSTALL.md. Requires After Effects 2019 (16.0) or newer.
