Ever wished you could have access to all your plugins when using Smart Objects, thus having Smart Filters? Here's how!
Make sure PS is not running.
For PSCS5 Mac:
Double click on this script and the adobe Script manager will run. You don't have to do anything other than close the manager once it's run. Start PS and open a file and convert a layer to Smart Object, hold cmd and click on the layer to select it, and go up to your filters menu. You should now have access to all filters! Finally!
For PSCS4 Mac:
You may get a Script Alert dialog for CS4, in which case simply click 'YES'.
I hope you may find this a useful tip! I certainly have.
