Installation

KoreSelect works with Blender 3.6 and above. To install, go to Edit > Preferences > Add-ons and click "Install from Disk." Select the downloaded .zip file — no need to extract it first. Enable "KoreSelect" in the addon list and you're ready to go.

Getting Started

KoreSelect is accessed through Edit Mode (for mesh selection) and Object Mode (for object-level tools). The main entry point is the context menu:

L — Opens the KoreSelect context menu with all available tools

The menu adapts automatically to your current mode (vertex, edge, face, or object) and only shows relevant tools

Interactive Selection Tools

Every KoreSelect tool runs as an interactive modal — you see results in real time and adjust parameters with your scroll wheel before confirming. No guessing, no redo panel hunting.

Common controls across all modals:

Scroll — Adjust the primary parameter (angle threshold, tolerance, etc.)

LMB / Enter — Confirm selection

ESC / RMB — Cancel and restore your original selection

Edge & Face Loops

Select edge loops and face loops with an adjustable angle threshold. The loop walker respects your mesh topology and stops at sharp turns.

Scroll — Adjust angle threshold (tighter = shorter loops, looser = longer loops)

1 / 2 — Switch between Loop and Ring mode

A — Toggle loop axis direction (face mode)

P — Toggle pole traversal (continue loops through 3/5-sided vertices)

B — Cycle boundary behavior (None, Sharp, Seam)

Shift+Scroll — Parallel expand (select adjacent parallel loops)

Double-click any edge or face to instantly select its loop without opening the modal.

Waypoint Path

Click to place waypoints on your mesh, and KoreSelect traces the shortest path between them. Works with edges, vertices, and faces.

LMB — Place a waypoint

Scroll — Adjust angle threshold

Backspace — Remove last waypoint

Enter — Confirm the full path

Similar Shape

Select one face group or edge pattern, and KoreSelect finds all matching shapes across your entire mesh. Uses native Rust computation for speed — handles thousands of faces in milliseconds.

Scroll — Adjust similarity tolerance

Supports scale-invariant matching (finds the same bolt cap regardless of size)

Select Surface

Click a face and KoreSelect flood-fills across connected faces that share a similar angle, selecting an entire continuous surface region. Ideal for selecting flat panels, curved sections, or any coherent surface area.

Select by Material / Normal / Size / Weight

Filter your selection by geometric properties:

Material — Select all faces sharing the same material slot

Normal — Select faces pointing in a similar direction (adjustable threshold)

Size — Select edges or faces within a size range

Weight — Select vertices by vertex group weight value

Nth Selection

After making any selection, use Nth Selection to thin it out with a keep/skip pattern. Perfect for creating evenly-spaced selections from a dense loop.

Scroll — Adjust skip count (every 2nd, 3rd, 4th...)

Ctrl+Scroll — Adjust keep count

Shift+Scroll — Shift the pattern offset

I — Invert the pattern

Edge Filter

Quickly select all boundary edges, sharp edges, or seam edges in your mesh. Switch between filter types with number keys.

Boolean Selection

Combine two selections with boolean logic — intersect, union, or subtract. Save a selection to group A, make a new selection, then boolean them together.

Selection Groups

Save any selection as a named group and restore it later. Works across vertices, edges, faces, and objects. Groups persist with your .blend file.

Ctrl+G — Save current selection to a group

Groups appear in the N-panel sidebar under the KoreSelect tab

Click any group to restore its selection instantly

Object Mode Tools

KoreSelect also works in Object Mode:

Select by Type — Quickly select all meshes, curves, cameras, lights, etc.

Hierarchy Selection — Select parent, children, siblings, descendants, or root objects

Similar Size — Find objects with similar volume, dimensions, or surface area

Object Groups — Save and restore object selections

Expand & Contract

Grow or shrink your current selection by one element ring at a time. Available from the context menu or as an interactive modal with scroll control.

Mark / Clear Edges

In edge mode, quickly mark or clear edge attributes (sharp, seam, crease) with an interactive modal — preview the result before applying.

Default Shortcuts

Shortcut Action

L KoreSelect context menu

Alt+L Smart loop select

Shift+L Select edge ring

Double-Click Smart select loop

Shift+Double-Click Extend selection with another loop

Ctrl+Double-Click Select surface

Ctrl+G Save selection to group

Ctrl+Shift+B Select boundary edges

Ctrl+Shift+S Select sharp edges

All shortcuts can be customized in Blender's Keymap preferences (search for "kore_select").

Performance

Core algorithms run in Rust via native compiled libraries, keeping interactive feedback snappy even on dense meshes. The angle-based loop walker, shortest path, and similar shape matching all run natively — you get real-time results as you scroll.

Compatibility

Blender 4.2+ (tested up to 5.0)

macOS (Apple Silicon + Intel), Linux (x86_64, ARM64), Windows (x86_64)

Works alongside other selection addons without conflicts
