houdini-animation

Typed animation tools for agents. All tools are affinity: main.

Tool groups

timeline: get_timeline, set_timeline — the canonical timeline query/setter. For interactive timeline edits prefer set_timeline over houdini_automation__set_frame_range (which remains for file-based batch flows).
keyframes: set_keyframe, get_keyframes, delete_keyframes (destructive).
channels: list_animated_parms, get_channel_info, export_channels, import_channels (JSON round-trip).
bake (async): bake_channels (per-frame sample → constant keys, hard frame cap), cache_simulation (render a filecache/DOP/geometry ROP, report written_files + elapsed_secs).

Tracer-bullet flow

set_timeline(frame_range=[1,48], fps=24)
set_keyframe(node_path="/obj/geo1", parm_name="tx", frame=1, value=0)
set_keyframe(node_path="/obj/geo1", parm_name="tx", frame=48, value=10)
get_keyframes("/obj/geo1", "tx") → verify two keys
export_channels("/obj/geo1", ["tx"], "/tmp/tx.json") → import_channels to retarget
bake_channels("/obj/geo1", ["tx"], frame_range=[1,48]) to flatten expressions

cache_simulation is async with a 1-hour timeout hint; output-path parm names are probed defensively so File Cache, DOP I/O, and Geometry ROPs are all tolerated.

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-lookdev

loonghao/dcc-mcp-houdini

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-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.
