houdini-lookdev

Authoring skill — lookdev and shader-network operations: inspect materials, libraries, shader nodes and assignments; get/set shader parameters with type-aware validation; inspect and rewire shader connections; reset assignments; and manage adapter-owned material presets. Pair with houdini-materials for material creation/assignment.

houdini-lookdev

Typed lookdev tools that complement houdini-materials (which creates and assigns materials). Most tools are affinity: main; the filesystem-only preset tools list_presets / delete_preset are affinity: any.

Tool groups

lookdev-query (read-only): list_materials, list_assignments, get_material_parms, get_shader_connections.
lookdev-edit: set_material_parms, connect_shader, disconnect_shader (destructive), reset_material (destructive).
presets: save_preset, list_presets, load_preset, delete_preset — JSON files under ~/.dcc-mcp/houdini/material_presets/ (override with DCC_MCP_HOUDINI_MATERIAL_PRESET_DIR).

Context limitations

Karma / MaterialX: MaterialX subnets live under a matnet/mat library; pass the exact material_path (the surface output node). Parameter names differ from principledshader, so prefer get_material_parms to discover names before set_material_parms.
VOP networks: connect_shader / disconnect_shader operate on node input slots; use get_shader_connections to read inputNames() first.
Presets store evaluated parameter values only (not node graphs); loading onto a different material_type is allowed but reported as a warning.

Tracer-bullet flow

houdini_materials__create_material(material_name="clay")
get_material_parms("/mat/clay") → discover parm names
set_material_parms("/mat/clay", {"basecolor": [0.8,0.4,0.2], "rough": 0.6})
houdini_materials__assign_material("/obj/geo1", "/mat/clay")
save_preset("/mat/clay", "warm_clay") → load_preset onto another material

houdini-pipeline

loonghao/dcc-mcp-houdini

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.

houdini-camera-light

loonghao/dcc-mcp-houdini

Authoring skill — create and edit cameras and lights, frame the Scene Viewer, and report active camera/view state through typed tools. Pair with houdini-render for viewport capture and ROP render execution.

2026-05-301

houdini-render

loonghao/dcc-mcp-houdini

Pipeline skill — viewport capture/flipbook plus ROP render settings and render execution through typed, runtime-aware tools. Exports report written_files, elapsed time, and warnings without hanging the host. Pair with houdini-camera-light to set up cameras and lights first.

2026-05-301

houdini-animation

loonghao/dcc-mcp-houdini

Pipeline skill — typed timeline, keyframe, channel, and cache-baking tools. Query/set time, FPS and ranges; set/get/delete/list keyframes; inspect channels and expressions; export/import channel JSON; bake channels and trigger bounded simulation/cache renders. The canonical timeline API.

houdini-interchange

loonghao/dcc-mcp-houdini

Interchange skill — load-on-demand import/export of Houdini geometry and scenes through production formats (native bgeo/geo, OBJ, Alembic, FBX, USD) plus filesystem probing. Use these typed tools instead of hand-building ROP/LOP/SOP networks with raw scripts.

2026-05-301

houdini-automation

loonghao/dcc-mcp-houdini

Pipeline skill - run file-based Houdini Python automation, manage hip files, set timeline ranges, and build small node chains from structured specs. Use when orchestrating repeatable Houdini tasks. Not for inspecting a scene only.
