Hardops 26: Lead is a hard surface modelling toolkit for Blender that is non-destructive by nature and destructive by choice. Its modifier-based workflow keeps you working in the 3D viewport, and while hard surface is the main focus, the tools extend across design from modelling through rendering.
You can reach its tools through a menu, pie, N-panel or active tool, and pressing Q brings up a menu that dynamically updates as you work. It includes a non-destructive or destructive boolean cutting system, the interactive hopsTool viewport modifier dot system, smart shapes for getting started with modifier modelling, mirroring with modifier, bisect and symmetry options, and a dynamic circular array that rotates from the origin or 3D cursor.
A viewport configuration system under alt + V handles solid, look-dev and render setups, alongside a simplified render N-panel. The toolkit is customisable from text size to operator style, has been used in film, AAA gaming and education, and ships with free updates.
