Authoring skill - create and assign Houdini materials, including typed MaterialX PBR networks for Karma. Use when building lookdev/material workflows from color, roughness, metallic, normal, or displacement maps. Not for generic node graph edits.

Pipeline skill — viewport capture/flipbook plus ROP render settings and render execution through typed, runtime-aware tools. Exports report written_files, elapsed time, and separate error/warning diagnostics without hanging the host. Pair with houdini-camera-light to set up cameras and lights first.
Scene skill — read-only inspection of the active Houdini hip file and node graphs. Use when you need frame range, hip path, object-level nodes, or node details. Not for creating geometry, sims, or exports — use authoring or interchange skills.
Authoring skill — inspect and edit Houdini node parameters, parameter templates, spare parameters, and channel expressions through typed atomic tools. Use instead of arbitrary Python for reading/setting parms, adding spare parms, and managing expressions. For node connections use houdini-node-graph.
Pipeline skill — generic, adapter-owned project and shot/package automation: set/query the project root, tag and read portable asset metadata, validate a scene for missing files / bad output dirs / dirty state / cook errors, collect file dependencies into a manifest (no copying), and export a shot/package manifest (frame range, cameras, output nodes, caches, written files). No dependency on private production services.
Scene-management skill — typed Houdini scene lifecycle (new/open/save with dirty-scene safeguards), selection (get/set/find), camera discovery, and bounding-box queries. Use these atomic tools instead of arbitrary Python for everyday scene navigation and file operations. Not for node authoring (use houdini-nodes) or geometry/transform edits (use houdini-object-ops).
Set up dcc-mcp-houdini for an agent or operator: install Houdini Python dependencies with hython, generate MCP host configuration, guide the user through the Houdini package / 123.py autostart load step, and run a first live-tool smoke prompt.

Typed material authoring for Houdini scenes. Use create_material for material
network nodes and assign_material for renderable OBJ/SOP nodes with a material
path parameter. Use build_materialx_pbr for a complete MaterialX Builder with
standard-surface, normal-map, and displacement outputs, then call
validate_materialx_pbr before assignment or rendering.
build_materialx_pbr treats base color as color data and roughness, metallic,
normal, and displacement as raw data by default. It removes the newly created
subnet if any node or connection fails; it never replaces an existing material.
