Blender’s loop cut shows you a yellow line at the midpoint of a segment, and where the cut actually lands only becomes clear once you have clicked and started sliding. Loopkut previews the loop under your cursor instead, so the position you are looking at is the position you get. It also handles the things the native tool leaves you to do afterwards: multiple offset loops, edge flow, and snapping to real distances.
What It Does
- Live preview that follows the mouse rather than snapping to the segment midpoint
- Inserts multiple loops at once, with offset and mirroring
- Set Flow mode smooths new loops to follow the surrounding edge flow instead of cutting straight across curvature
- Planar bisect mode with multi-segment support
- Snaps to divisions, fixed distances, vertices and edge increments — so a supporting loop can go exactly 2 mm from an edge rather than roughly there
- Modal shortcuts mid-operation for Even, Flip, Mirrored and Perpendicular
- An F9 panel to adjust the cut after committing, plus customisable keymaps and preview colours
How You Use It
Press C in Edit Mode, hover the mesh to preview, scroll to change the loop count, left-click to confirm and slide, right-click or Esc to cancel.
Good To Know
- Free and open source under GPL-3.0-or-later, by KewlSheet, with a Discord for support
- Version 1.4.0, Blender 4.2 LTS and newer, 103 KB, no permissions requested
- 16,400+ downloads on Blender Extensions, rated 5.0 from 7 reviews
- The default key is C, which is Circle Select in Edit Mode. One of the two has to move, and it is better to decide that on install than mid-model
- Reviewers report not finding the incremental snapping and Active Tool options in the sidebar that appear in the demo video — budget some time hunting for settings
- Written documentation is the gap people name most often. Support is a Discord invite rather than a manual, which matters if you would rather read than ask
Where It Fits
Worth it for modellers who reach for loop cut constantly — hard-surface work, retopology, anyone adding supporting loops all day. Set Flow and distance snapping are where the time actually comes back, on curved surfaces and on parts that need measured spacing. If you cut a handful of loops a week, Ctrl+R already does that job and this is one more keymap conflict to manage for little return.
