As an alternative to the existing python plugins, Substance Designer now supports plugin packages.
Plugin packages are single files with a sdplugin extension containing everything a plugin needs to work.
For developers, packages simplify sharing and distributing plugins to users. For users, packages are easier to install and manage.
Installing plugin packages
Plugin packages are installed using the Plugin Manager, in the Tools menu.
Click on the install button and select the plugin package to install.
The plugin will be installed in the home directory, in the default path for plugins for each
operating system. After the plugin is installed, it will be automatically loaded.
