Lazy Weight Tool earns its place in the superhive library by pulling weight editing, numeric weight setting, and mesh-style selection into Blender's weight paint mode, with support spanning Blender 2.79 through 5.1.
Lazy Weight Tool is a Blender add-on built around editing and assigning weights during weight painting. Its Weight Table shows vertex weights and assigned vertex groups so you can view and edit them directly, highlight a specified value by Match, More, or Less, and optionally display vertex index on the mesh. Note that adjusting a value in the table alone does not trigger automatic normalization.
Weight setting covers Flood weight and fixed numbers such as 1.0, 0.9, 0.75, 0.5, 0.25, 0.1, and 0.0, assigning values for the current brush settings and normalizing all at runtime. Weight Copy/Paste copies the weights of selected vertices to the clipboard and pastes them into another mesh or object, and an Adjust Weight Gesture sets weight by moving the mouse with Shift + Alt + F.
Selection stays fluid in weight paint mode, with loop and shortest path selection by clicking as in mesh editing, plus select more, select less, and multi loop. It also adds a Weight Transfer menu, a mini brush setting menu, and a 3-column vertex group panel with regular expressions. It supports Blender 2.79 through 5.1, and a demo video is available.
Lazy Weight Tool is best for blender artists who weight paint and want to edit weights in a table, assign numeric or flood weights, copy weights between objects, and select vertices without leaving weight paint mode.
Lazy Weight Tool is completely free to download and use.
Lazy Weight Tool supports Blender versions 2.79 through 5.1, covering a wide span of releases from older builds to recent ones. If you work across several Blender installations, that range means the add-on's weight table, numeric weight setting, copy and paste, and selection tools should be available in most versions you are likely running. For the exact behavior in a specific release and to confirm current compatibility, check the developer's page and documentation before installing.
Lazy Weight Tool is listed as free here and is released under the GPL license. Because licensing can change over time, it is worth checking the developer's page for the current terms before you rely on it in a project. The GPL license covers how the add-on can be used, modified, and shared. For the most accurate and up-to-date details, the developer's page and documentation are the best reference.
Lazy Weight Tool includes a Weight Copy/Paste feature that copies the weights of selected vertices to the clipboard, then pastes them into another mesh or object. This is especially useful when you want to match the weights of separated meshes and other objects. The copy and paste steps work through the clipboard, so weights carry from one selection to another. For the full set of options and any limitations, the developer's documentation is the place to look.
Lazy Weight Tool lets you select vertices smoothly while still in weight paint mode, with loop selection and shortest path selection available by clicking as in mesh editing mode. It adds select more with Ctrl + Numpad +, select less with Ctrl + Numpad -, select multi loop, edge loop with Alt + left double click, and select link with L. An Adjust Weight Gesture also sets weight by moving the mouse with Shift + Alt + F.
