Restart Natron.

The plugins can be installed by simply cloning the github repository at the right location, for example on Linux:

cd /usr/share/Natron/Plugins
git clone https://github.com/NatronGitHub/natron-plugins.git

Later, the plugins can be updated at any time by pulling updates:

cd /usr/share/Natron/Plugins/natron-plugins
git pull

To install a snapshot of the repository, download it as a ZIP file via https://github.com/NatronGitHub/natron-plugins/archive/master.zip

Unzip into any PyPlug folder but the recommended locations are...

Windows: "C:\Program Files\INRIA\Natron-2.X.XX\Plugins\PyPlugs"

OSX:     "/Library/Application Support/Natron2/Plugins/PyPlugs"

Linux:   "[/usr/share] or [YOUR INSTALLATION DIRECTORY]/Natron2/Plugins/PyPlugs"

For Shadertoy presets: copy the natron-plugins-master/Shadertoy contents and replace it in the following links:

Windows: "C:\Program Files\INRIA\Natron-2.X.XX\Plugins\OFX\Natron\Shadertoy.ofx.bundle\Contents\Resources\presets\default"

OSX:     "/Library/Application Support/Natron2/Plugins/OFX/Natron/Shadertoy.ofx.bundle/Contents/Resources/presets/default"

Linux:   "[YOUR INSTALLATION DIRECTORY]Natron2/Plugins/OFX/Natron/Shadertoy.ofx.bundle/Contents/Resources/presets/default"

Finally edit the plugins location in Natron preferences to allow it to find them during startup, if it's not already. If you want a particular folder only you can use http://kinolien.github.io/gitzip/ and put the URL to the folder you want there. Also you can install individual .py files (and their accompanied png icon files).

We'd love to add your own Pyplugs to this repository so everyone can benefit from them.

You can make a Pull Request or if you're not comfortable with git just tell us here :

Also you can look at our guidelines for Pyplug submission :
