UV Flow is a Blender add-on for UV unwrapping that adds a Cut UV tool to the toolbar for marking seams, with context-aware straightening, seam layers, and per-material packing.

STL format (legacy) is a Blender add-on for importing and exporting STL files. Previously part of Blender 4.1's bundled add-ons, it's now offered as it is with limited support and lives under File → Import-Export.

MustardUI is a Blender add-on that builds an intuitive interface for human character models. It handles outfits, hair, morphs and custom properties from panels inside Blender, with no Python required.

Node Pie is a Blender add-on that converts the standard add-node menu into a pie menu inside the node editor, letting you add nodes with Ctrl + click, socket dragging, or link insertion for faster, muscle-memory-based work.

Zen UV Checker is a Blender add-on for inspecting UV layouts using checker textures. It applies checker maps through a node-based system without altering existing materials or creating new ones, and includes a one-click setup.

BlenderAe2 by Salt Media transfers 3D data and objects between Blender and After Effects in both directions, covering vertices, 3D layer transforms, camera data and layer synchronization.

Machin3Tools is a continuously evolving collection of tools and pie menus for Blender, gathered in a single customizable package. It ships in two base variants, Prime and DeusEx, with the DeusEx variant adding more advanced tools.

3D Print Toolbox is a Blender add-on with utilities for 3D printing. It analyzes mesh volume and surface area, checks and fixes geometry, hollows shapes, aligns models to the print bed, and exports to STL, PLY, and OBJ.

UVPackmaster 4 is a UV packing engine for Blender that packs UV maps on the CPU and GPU, using the Cuda and Vulkan APIs, and can run on the CPU and all system GPUs at once.

MMD Tools is a Blender add-on for editing MikuMikuDance (MMD) models. It handles importing and exporting model, motion and pose data, along with chopping and joining parts, plus rigid body, material and motion editing.

SimpleBake brings PBR and traditional texture baking to Blender from a single panel. Select objects, choose maps, and bake — no special node groups or new workflow, working with whatever materials you've already built.
