Hi there! is there a way to delete unused textures at least to locate them and delete them by hand? TM is warming me with old textures files not present in scene each time I open it. Thanks!
Yes, as @reididrub highlighted, it is possible in 2023.2.2 through a button.
On previous versions, you have to control shift to select all your library material and press ‘delete’. unused material will be deleted, used materials won’t be impacted.
