Addon ScaffoldingAScaffold a Blender add-on as an Extensions Platform package: blender_manifest.toml, modular file layout, register_classes_factory, symmetric register/unregister. Use when the user starts a new add-on or extension, writes or fixes blender_manifest.toml, asks which layout or registration pattern to use on Blender 4.5 LTS or 5.x, or has classes that fail to register or unregister cleanly. Targets 5.2 LTS with 4.5 LTS fallback.developmentpythongoVotes: 0GitHub stars: 16
Ai Mesh CleanupAOrdered cleanup for an imported generated or scanned mesh before it goes to an engine: scene units, apply rotation and scale, origin to base, recalculate normals, evaluated triangle count, decimate to a budget, convex collider. Use when the user has a GLB, glTF or FBX that is not engine-ready, mentions unit scale, unapplied transforms, triangle budget, LODs or a collision hull, or is about to run mesh operations on an import without checking its scale. Targets 5.2 LTS with 4.5 LTS fallback.developmentpythongoVotes: 0GitHub stars: 16
Bake High To LowACage-bake high-poly surface detail onto a low-poly target as a tangent-space normal map with bpy.ops.object.bake (Cycles, selected-to-active, active Image Texture node, UV layer, save_render). Use when the user wants a normal map from a dense mesh onto a game-resolution or decimated LOD, mentions cage_extrusion or use_selected_to_active, or gets a bake that returns CANCELLED, comes out black or flat, or fails with 'No active UV layer found'. Targets 5.2 LTS with 4.5 LTS fallback.developmentpythonnodeVotes: 0GitHub stars: 16
Bl Info MigrationAMigrate a legacy bl_info add-on to the Extensions Platform in three steps, with a before/after diff and the dual-format pattern. Use when the user has a bl_info dictionary in __init__.py, asks whether bl_info is deprecated or still supported, wants to publish to extensions.blender.org or ship an extension .zip, or sees warnings about legacy add-ons at install time. Targets 5.2 LTS; manifests work from 4.2.developmentpythongoVotes: 0GitHub stars: 16
Custom PropertiesADefine and bind custom properties with bpy.props annotations, PropertyGroup and PointerProperty, and choose where to store them (Scene, Object, WindowManager, AddonPreferences). Use when the user attaches settings or data to datablocks so it survives save and load, is unsure where add-on settings belong, or writes a property as an assignment instead of an annotation and gets a deprecation warning or a _PropertyDeferred value. Targets 5.2 LTS.developmentpythongoVotes: 0GitHub stars: 16
Depsgraph And Evaluated DataARead the evaluated geometry the user actually sees through the dependency graph instead of raw obj.data: evaluated_depsgraph_get, evaluated_get, to_mesh and to_mesh_clear lifetimes. Use when the user writes an exporter, measurement or inspection script, reports that modifiers, shape keys, armatures or geometry nodes are missing from exported or measured geometry, or reads obj.data.vertices and gets the undeformed base mesh. Targets 5.2 LTS.developmentpythongoVotes: 0GitHub stars: 16

Drivers And App HandlersADrive properties from expressions with the Driver API (driver_add, driver_namespace for custom Python functions) and react to events with bpy.app.handlers (load_post, save_pre, frame_change_post, depsgraph_update_post, exit_pre in 5.1+). Use when the user wants one property to follow another, runs code on load, save, frame change or exit, or has a driver failing with NameError or the Python security block, including drivers that die after reopening a file.developmentpythonreactVotes: 0GitHub stars: 16
Engine Export PresetsAExport presets for Unity, Godot and Unreal. glTF is +Y up and meters by spec, so every engine gets export_yup=True with no scale bake (Unreal converts to centimeters on import); FBX takes axis_forward/axis_up plus global_scale. Use when the user exports for a game engine, mentions export_yup, axis_forward, axis_up, global_scale, Y-up or centimeters, passes FBX axis kwargs to export_scene.gltf, or gets a model that imports lying on its back or 100x too large.

Geometry Nodes PythonABuild Geometry Nodes trees from Python: node_groups.new, tree.interface sockets, nodes by RNA identifier, links, Repeat and for-each zones, Bundles, and applying the tree as a NODES modifier including the 5.1 vs 5.2 modifier input API. Use when the user generates a GeometryNodeTree in a script, sets modifier inputs from Python, or hits 'Node type ... undefined' or socket identifier errors. Targets 5.2 LTS with 4.5 LTS fallback.developmentpythonnodeVotes: 0GitHub stars: 16
Headless Batch ScriptingARun Blender unattended with blender --background --python, arguments after the -- separator, --factory-startup and --python-exit-code, and temp_override for operators that need context. Use when the user renders, exports or processes .blend files from a CLI, CI job or batch script, passes arguments to a Blender script, or hits 'poll() failed, context is incorrect' or a job that exits 0 despite a Python traceback. Targets 5.2 LTS with 4.5 LTS fallback.developmentpythongoVotes: 0GitHub stars: 16
Mesh Editing And BmeshACreate, edit and read meshes efficiently: when to use bpy.data, bpy.ops or bmesh, the bmesh.new / try / finally / free pattern, foreach_get and foreach_set for bulk data, and evaluated meshes for modifier results. Use when the user writes mesh-generating or mesh-editing Python, mentions bmesh, from_pydata, foreach_set or mesh.vertices, has a slow script looping over bpy.ops.mesh or per-vertex assignments, or a bmesh script that misbehaves on its second run. Targets 5.2 LTS.developmentpythonrustVotes: 0GitHub stars: 16
OperatorsAAuthor bpy.types.Operator classes: bl_idname naming, poll / invoke / execute / modal lifecycle, bl_options (REGISTER, UNDO, INTERNAL, BLOCKING), operator properties and defensive context handling. Use when the user creates an operator for a button, menu, keymap or script, asks why its properties are missing from the Adjust Last Operation (redo) panel or why Ctrl-Z ignores it, or gets poll failures or None context objects. Targets 5.2 LTS with 4.5 LTS compatibility.developmentpythongoVotes: 0GitHub stars: 16
Procedural Materials And ShadersABuild materials and shader node graphs from Python: bpy.data.materials, node_tree, Principled BSDF and its 4.0+ socket names, default values, links and shader node groups, for EEVEE and Cycles. Use when the user creates or edits materials in a script, generates many material variations, hits a KeyError on a Principled BSDF input such as Specular or Emission, or asks about EEVEE vs Cycles differences or the deferred Layered Textures system. Targets 5.2 LTS.developmentpythongoVotes: 0GitHub stars: 16
Slotted Actions AnimationACreate and edit animation from Python under Slotted Actions (Blender 4.4+): Action, slots, layers, strips, channelbags. Bind the action slot, then reach F-curves through a channelbag; action_ensure_channelbag_for_slot exists only on 5.0+, so use strip.channelbag(slot, ensure=True) on 4.5 LTS. Use when the user inserts keyframes or builds F-curves in a script, hits AttributeError on action.fcurves in 5.x, or has keys that exist but never play back. Targets 5.2 LTS with 4.5 LTS fallback.developmentpythongoVotes: 0GitHub stars: 16
Ui PanelsAAuthor bpy.types.Panel UI: bl_space_type, bl_region_type, bl_category sidebar tabs, declarative draw(), layout row, column and split, sub-panels, and conditional UI with enabled and active. Use when the user adds an N-panel tab or properties-editor panel, exposes add-on properties or operator buttons, or has a panel that does not appear, shows the wrong labels or warns about a missing _PT_ in its bl_idname. Targets 5.2 LTS.developmentpythongoVotes: 0GitHub stars: 16
Vse PythonABuild and inspect Video Sequence Editor timelines from Python: SequenceEditor.strips vs the removed .sequences, new_effect length vs frame_end, strip transforms, and the 5.2 COLOR strip width/height bake from scene resolution. Use when the user scripts the sequencer, hits AttributeError on sequence_editor.sequences in 5.x or a TypeError on new_effect keyword arguments, or renders COLOR strips that ignore transform scale after a resolution change. Targets 5.2 LTS with 4.5 LTS fallback.developmentpythongoVotes: 0GitHub stars: 16
Blender RulesABlender Python anti-pattern rules (bmesh leaks, bpy.ops in loops, deprecated context-copy overrides, bulk mesh writes, prop annotations and context guards, Extensions manifest, import scale, export modifiers, glTF/FBX axis RNA). Use when writing, reviewing or fixing any bpy / Blender add-on or script code.developmentpythongitVotes: 0GitHub stars: 16
Extension Runtime And PackagingAShip and run a Blender extension after its first install: bundled wheels, user data that survives upgrades via bpy.utils.extension_path_user, the network permission and bpy.app.online_access, bl_ext package names, and blender --command extension validate/build/server-generate in CI. Use when the user bundles third-party Python packages, pip-installs into Blender's Python, writes files next to __file__, needs a settings or cache directory, makes network calls from an add-on, or builds and publ...developmentpythongoVotes: 0GitHub stars: 16
Timers Modal And ThreadingARun long or repeated work in a Blender add-on without freezing or crashing it: bpy.app.timers return values and persistent=True, modal operators driven by event_timer_add, and worker threads that hand results to the main thread through a queue. Use when the user polls, animates or downloads from an add-on, calls bpy from a thread, writes a modal operator, sees a timer never fire in --background, or loses a timer after opening a file.
