houdini-chops
Typed CHOP tools for agents. All tools are affinity: main.
Tool groups
network: create_chop_network — create and manage CHOP container networks.
motion: create_motionclip — import or create motion clip CHOPs for
animation data.
audio: create_audio_driven — set up audio-driven animation channels
using Audio/Envelope CHOPs.
filter: apply_filter — apply procedural CHOP filters (lag, spring,
noise, smooth).
export: export_to_keyframes — bake CHOP channel data to object
keyframes.
inspect: get_channel_info — inspect CHOP node channels (names, sample
rate, length, value range).
Tracer-bullet flow
create_chop_network(network_path="/ch/motion_fx")
create_motionclip(network_path="/ch/motion_fx", node_name="walk_cycle", clip_file="/tmp/walk.bclip")
apply_filter(network_path="/ch/motion_fx", source_node="walk_cycle", filter_type="lag", amount=0.5)
get_channel_info(node_path="/ch/motion_fx/lag1")
export_to_keyframes(node_path="/ch/motion_fx/lag1", target_path="/obj/geo1", parm_names=["tx", "ty"])
create_audio_driven can point at a .wav file or use an existing audio node.
The envelope follower produces amplitude-driven channels that can be wired to
any object parameter.
