You can import Toon Boom Studio templates (.tbt) in local or global library, clicking on the name of them in the library pane and then right-click in the area that hosts it´s content (right box in the library), a drop-down menu appears, click on import / import template file. Browse the directory of your templates, select them and open, your templates are saved in your project (when you save it), if local, or accessed from any project if saves them onto the global library. Always the program asks whether to save the changes in libraries.
You can also build new libraries or catalogs to save your templates with right-click on the name of Local or Global. Regards. Yoryo.
Where exactly, when downloading templates, are you supposed to save them? i.e. The free all star manga templates?
Thanks that helped a bunch. Problem solved.
