Guides Blender addon development - operators, UI panels, bpy.props, poll() methods and registration. Use when creating a Blender addon, building an operator or UI panel, or writing Blender Python for a tool.

Keyframe animation, rigging, constraints, and armatures in Blender. Use for animation, rigging, camera movement, or when user mentions "animate," "keyframe," "rig," or "armature."

Diagnoses and migrates Blender Python API breakage across versions 4.2 to 5.1+ (EEVEE_NEXT, renamed modifier types and BSDF inputs, VSE strips). Use when a bpy script errors on a newer Blender, or for breaking changes and migration.

Compositor nodes, post-processing, and color grading in Blender. Use for compositing workflows, render pass integration, post-processing, color correction, or when user mentions "compositor," "post-process," "color grade," or "render passes."

Renders ControlNet conditioning passes from a Blender scene for AI image and video generation - grey clay, normalized depth, cryptomatte EXR, optional wireframe. Use when preparing depth, edge or clay inputs for video models, or crypto mattes for comp.

Procedural modeling using Geometry Nodes in Blender. Use for scattering systems, node trees, parametric design, or when user mentions "procedural," "geometry nodes," "scattering," or "instances."

Builds 2D and mixed-media animation in Blender with Grease Pencil - strokes, layers, frame-by-frame animation, 2D/3D integration, NPR rendering. Use for 2D or hand-drawn animation, traditional animation, or any grease pencil request.

Creates Blender shader node trees, PBR materials and procedural textures, with EEVEE_NEXT and Cycles compatibility notes. Use for material creation, shader setups, Principled BSDF inputs, or procedural texturing of parametric geometry.

Sets up Blender physics simulations - particle systems, Mantaflow fluid, smoke and fire, rigid body, soft body, cloth and hair. Use for physics, particle, fluid, cloth or hair simulation requests in Blender.

EEVEE_NEXT and Cycles rendering, lighting, and render optimization in Blender. Use for rendering setup, lighting, render settings, or when user mentions "render," "lighting," "EEVEE," "Cycles," or "materials."

Terrain creation, organic modeling, and surface details using Blender sculpting tools. Use for terrain, organic shapes, sculpted details, or when user mentions "sculpt," "terrain," or "organic."
