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 keysexport_channels("/obj/geo1", ["tx"], "/tmp/tx.json") → import_channels to retargetbake_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.
