Okay, here is how I do it. I load my own plugin (effect). While keeping AE loaded, I recompile another version of the same plugin (with different UI controls, functionality, etc.) and issue the following command in /Applications/Adobe After Effects 7.0/Plugins/
directory:
rm -rf PluginName && ditto -rsrcFork DIRECTORY/PluginName.plugin PluginName.plugin
where, PluginName is the name of the Plugin, and DIRECTORY is where I compile it.
Then, I remove the the plugin in the AE, and do Edit->Purge All, and then reapply the plugin.
However, I do not see the updated plugin; just the older (orginally) loaded version.
If do not anything now, and quit AE, and then restart and reapply my plugin, then I see the new one.
Thanks for all the help.
Sincerely,
Qasim
