# ZeroBlender Blender-style modeling inside Zero. Install this package and you get the whole surface: the `.zblend` document type, the tools that edit it, the Python/bpy runtime behind them, the layer previews live in, and the workflow that drives a modeling job to the end. ## Contents | Path | What it is | |---|---| | `zblend.assetType/` | The `.zblend` document (Zero's `.blend`): editable `scene.json`, history, images, and a live `output.bundle`. Scene-instantiable, previewed, searchable. Its ref methods open and edit documents (below); `M.modules` exposes every module here to instances. | | `blender.toolbox/` | Blender MCP-compatible tools: `execute_blender_code`, `get_scene_info`, `get_object_info`, `get_viewport_screenshot`, `bpy_api_lookup`, `get_addon_status`, `compare_to_reference`. `api.json` is the implemented bpy surface. | | `modules/blenderSession` | The bpy/bmesh/mathutils session: objects, meshes, modifiers, materials, viewport, flush to the document and bundle. | | `modules/pythonParser`, `pythonRuntime` | The Python subset the scripts run in (Luau-hosted, not CPython). | | `modules/animation`, `rigging` | Armatures, pose, vertex groups, ARMATURE deform, auto weights, keyframes/actions/F-Curves, constraints, IK, drivers, NLA; clip baking. | | `modules/sceneOps` | Empties, duplicates, collections, collection instances, `zero_instance`, `origin_set`, cursor, snapping. | | `modules/curves`, `meshOps`, `polygonTopology`, `xform` | Curve/text meshing, edit-mode operators, topology and evaluation, matrix math. | | `modules/referenceCompare` | Silhouette scoring against a reference image. | | `modules/bpy`, `hardSurface`, `kestrel` | Older core geometry layer and hard-surface helpers used by the session. | | `workspace/ModelingWorkspace.scene` | Additive layer holding document previews, on render layer `modelingWorkspace` (hidden from the editor camera, drawn by screenshots). | | `model.workflow/` | Multi-pass modeling job: reference → model → critic/builder rounds → finish. | | `modeling.agentSkill/` | The `modeling` skill that starts the workflow. | ## Usage ```luau -- Make or open a document and edit it local doc = asset.create("zblend", "Lantern", { folder = "models" }) doc:run([[import bpy bpy.ops.mesh.primitive_cylinder_add(radius=0.1, depth=0.3)]]) doc:screenshot("ISO") doc:sceneInfo() doc:open() -- load as a live session, returns its name -- Place it (live: placed copies follow edits and play its clips) doc:instantiate(entity.find("Shelf")) -- Frozen copy doc:exportBundle("/zero/source/models/Lantern_v1.bundle") ``` Agents use the `blender` toolbox directly with `session="<folder>/<Name>"`, or start the `model` workflow for a full modeling job (`zero workflow start --name model --args '{"subject":"..."}'`). Documents default to `modeling/models/<name>.zblend`; user data (models, references, reports) is not part of the package.
