Haggis Tools is a Blender add-on (2.8+) from Online Render, geared toward optimizing workflows, reducing repetitive tasks, and saving artists time. The add-on gathers a broad set of utilities and keeps them within reach through quick menus and a set of non-intrusive icons in the top right of the Blender interface.
On the object side, it can copy and paste location, rotation, and scale, store and recall those transforms, duplicate objects and automatically join them, and add empties to selected vertices for instancing. Selection tools cover select by polycount, selecting objects disabled in the render engine, and locking inverted selection. Animation work runs through a quick menu opened with Alt + Right Click, where you can keyframe transforms, skip keyframes in user-set increments, and calculate or clear motion paths.
The top-right icons handle QuadView, gizmo toggles, name display, and camera view lock, and a user-specified editor can open as a floating window for dual-screen setups. The add-on ships with documentation, a video tutorial, and Discord support, and receives free updates.
