I'm trying to create a Photoshop Panel for some actions, but I want to know how can I check if the brush already exist in photoshop and if not exist to call a function to install it before the action can be used, I already know how install it, and how run the actions, but I still got some issues detecting if the brush exist on Mac/Windows environment.
Any tips about how do this using Javascript? (JSX)
You can get lists of brush or tool presets using this AM snippet. Note that several Brush Presets could have the same name.
