Pivot Master is a Blender add-on that re-assigns a mesh's Local Origin to any selected component in one click. It works from a single face, multiple faces, verts, or edges.

Axis Addon for Blender creates alignment axes in edit mode to help position objects, especially around axis and round holes. It builds axes through planes or three points and adjusts the 3D cursor accordingly.

Displace Painter is a Blender addon for painting displacement onto meshes through a layer-based system. Paint mountains, valleys, rivers, metal plating, exposed wires, or procedural damage while a simplified stack handles the modifiers behind the scenes.

EZdepth is an AI depth map generator for Blender that turns any image into a 3D surface. Select a photo and generate a depth map you can apply as a displacement modifier, shader setup, or grayscale image.

Surface Follow Addon binds meshes to the surface of other meshes in Blender. It works similarly to the surface deform modifier but a little differently, binding faster on large meshes without convex errors.

LoopTools is a mesh modelling toolkit for Blender that gathers several tools to aid modelling. It was previously part of Blender 4.1's bundled add-ons and is now offered as an extension, provided as it is with limited support.

Extra Mesh Objects is a Blender add-on that expands the Add > Mesh menu with additional mesh object types. Previously bundled with Blender 4.1, it now ships as a standalone extension for Blender 4.2 LTS and newer.

Bool Tool brings quick boolean operators to Blender for hard-surface modeling, covering brush booleans, destructive auto boolean cuts, and workspace tools that carve objects with custom shapes in both object and edit modes.

Extra Curve Objects is a community add-on for Blender that adds extra curve object types. It lives under View3D → Add → Curve → Extra Objects and was previously part of Blender 4.1's bundled add-ons.

MESHmachine is a mesh modeling addon for Blender focused on hard surface work without subdivision surfaces. It fuses and unfuses surfaces, creates variable fillets and washouts, edits bevels, and details meshes with plugs.

A.N.T.Landscape is a Blender add mesh add-on for generating landscapes and displacement. Originally a bundled add-on in Blender 4.1, it's now offered as-is with limited support, accessed from the View3D sidebar's Create tab.
