The phrase references a specific type of Blender extension that allows for the creation and manipulation of sculpted models using a layered approach, obtainable without cost. This functionality permits users to work on distinct aspects of a sculpture independently, similar to using layers in image editing software. For instance, one layer might contain fine details like wrinkles, while another handles broad form changes, allowing for non-destructive editing.
The availability of such tools is crucial for digital artists, enhancing workflow efficiency and enabling greater experimentation with sculpting techniques. By providing a way to separate and manage sculpting processes, these extensions contribute to a more organized and iterative creation process. Historically, comparable features were limited to commercial software, but the open-source nature of Blender fosters the development and distribution of freely accessible alternatives.
