Loopkut stands out in the blender_extensions library for what it adds over Blender's built-in Loop Cut and Slide: a preview that tracks the cursor rather than snapping to the midpoint, plus a bundled bisect mode. Version 1.3.3 is a code cleanup, and the add-on requires no special permissions.
Loopkut previews inserted loop cuts directly at your mouse position in Blender's Edit Mode, letting you place one or many loops precisely before committing. The preview loop follows your cursor along the edge, the scroll wheel adds or removes loops, a left-click confirms and slides, and another click places them. Right-click or Esc cancels, while holding Ctrl during a move snaps to the midpoint of the active edge.
Single and Multi Loop modes cover one loop or several evenly spaced loops, with snapping to divisions, fixed distances, vertices, and increments along the edge. Set Flow mode applies edge-flow smoothing to inserted loops, and Bisect mode adds planar cuts through the mesh with multi-segment support. All actions run in a single modal tool with rebindable shortcuts.
Preferences cover a configurable activation key, a rebindable modal keymap, a choice of cancel key, Industry Compatible Keymap support, and color and size settings for every preview element. An F9 Adjust Last Operation panel exposes settings for both loop cuts and bisect, and full undo/redo works through the standard operator redo panel.
Loopkut is best for blender modelers inserting loop cuts and planar bisect cuts in Edit Mode with previewed, cursor-position placement.
Loopkut is completely free to download and use.
Loopkut lists compatibility with Blender 4.2 LTS and newer, so it targets recent releases rather than older builds. It runs in Edit Mode, where the preview loop follows your cursor along an edge and you scroll the mouse wheel to add or remove loops. The add-on is a small download at roughly 102 KB and requires no special permissions. If you're on an earlier Blender version, check the developer's page and version history to confirm which releases are supported before installing.
Loopkut starts in Edit Mode by pressing C, the default key, which you can reconfigure with optional Ctrl, Shift, or Alt modifiers in the preferences. You can also pick the Loopkut tool from the toolbar. Once active, hover over the mesh and a preview loop follows your cursor; scroll the wheel to change the loop count, left-click to confirm and slide, then click again to place. Right-click or Esc cancels, and you can choose which of those two acts as the cancel key.
Loopkut is listed as free here in the catalog, and it's distributed under the GNU General Public License v3.0 or later. For current licensing terms and download options, check the developer's page from KewlSheet. The extension states that it requires no special permissions, and installation is by drag and drop into Blender or by downloading and installing from disk. Licensing details can change over time, so confirm the latest information on the official listing before relying on them.
Loopkut ships with a fully rebindable modal keymap, so every in-tool action can be reassigned in the preferences. The activation key defaults to C with optional Ctrl, Shift, or Alt modifiers, and you can choose whether Right-click or Esc cancels the operation. It also supports Blender's Industry Compatible Keymap. Preview colors and sizes are customizable too, covering elements like the loop line, Set Flow line, bisect preview, snap points, and indicators. Alt plus left-click passes through to Blender so you can orbit and pan mid-operation.
Loopkut includes a Bisect mode you enter by pressing B while the tool is running, giving planar cuts with a live preview of the cut plane. It supports multi-segment cuts, selection-only cutting via G, and a spacing reference set to either the active edge locally or the whole mesh globally with L. A dedicated F9 panel exposes bisect options including move, axis, segments, loop offset, and merge distance, so you can adjust the result after placing the cut.
