Adds a collection of geometry channels to the channel list, constructed from the channel primitives present in the provided geometry. Returns the name of the geometry channels collection. If no name is provided, a unique name will be created. Note that any modifications to the scoped channels are not immediately reflected in the channel primitives, but must be manually updated using hou.anim.mergeGeometryChannels.

The following shows an example workflow of adding geometry channels to the channel list, listening for updates, and setting modified channels back in to channel primitives:

channel_list = hou.ChannelList()
collection_name = "test_collection"
# g is any hou.Geometry with channel primitives.
channel_list.addGeometryChannels(g, collection_name)
hou.playbar.setChannelList(channel_list)

# Mutable geometry in which to write modified channel primitives.
output_geometry = hou.Geometry()

def channels_changed(channel_names, collection_name):
    print(f"Channels in {collection_name} were modified: ", channel_names)

    # Write the changed channels back in to channel primitives.
    hou.anim.mergeGeometryChannels(collection_name, output_geometry, channel_names)

# Called whenever geometry channels added to the channel list are modified,
# such as when they are edited in the Animation Editor.
hou.anim.addGeometryChannelsChangedCallback(collection_name, channels_changed)
