Overall, we have tried to adhere to the same principles as in the development of version 1.0. We've designed MetaReForge addon interface to be as clear and structured as possible. All features are organized into blocks within the N-panel under the 'MRF' category. The majority of these features are accessible in object mode, while additional utilities for armature editing become available in armature and mesh edit modes. ### Preliminary Setup @@ -11,15 +11,13 @@ First, we need to prepare the files for editing.
