With synoptic retired, I was looking for the ‘new’ official way of baking ik to kf and vice versa without the UI in code. I do this after retargeting mocap to get more accurate IK animation from the FK mocap.
Here’s my attempt ( I copied and replicted what the right-click menu is doing )
( Please note that the call at the end is just test-code, you’ll probably want to call this in the ‘correct’ way in your code )
from mgear.core import anim_utils
from mgear.core.dagmenu import _list_rig_roots, _find_rig_root, _get_switch_node_attrs, get_ik_fk_controls_by_role
import pymel.core as pm
import maya.cmds as cmds
def range_switch_exec(ui_host, switchTo, onlyKeyframes, start_frame, end_frame):
range_switch = anim_utils.IkFkTransfer()
switch_control = ui_host.name()
blend_attr = _get_switch_node_attrs(ui_host.name(), "_blend")[0]
root = _find_rig_root(ui_host.name())
criteria = blend_attr.replace("_blend", "") + "_id*_ctl_cnx"
component_ctl = (
cmds.listAttr(switch_control, ud=True, string=criteria) or []
)
if component_ctl:
ik_list = []
ikRot_list = []
fk_list = []
upv_list = []
for com_list in component_ctl:
# set the initial val for the blend attr in each iteration
ik_controls, fk_controls = get_ik_fk_controls_by_role(
switch_control, com_list
)
ik_list.append(ik_controls["ik_control"])
if ik_controls["ik_rot"]:
ikRot_list.append(ik_controls["ik_rot"])
upv_list.append(ik_controls["pole_vector"])
fk_list = fk_list + fk_controls
range_switch.execute(
model=root,
ikfk_attr=blend_attr,
uihost=pm.PyNode(switch_control).stripNamespace(),
fks=fk_list,
ik=ik_list,
upv=upv_list,
ikRot=ikRot_list,
startFrame=start_frame,
endFrame=end_frame,
onlyKeyframes=onlyKeyframes,
switchTo=switchTo
)
if __name__ == "__main__":
sel = pm.ls(sl=True)[0]
range_switch_exec(
sel, switchTo='ik',
onlyKeyframes=False,
start_frame=int(pm.playbackOptions(query=True, min=True)),
end_frame=int(pm.playbackOptions(query=True, max=True)),
)
Doing this I found what I think was a bug in mgear.core.anim_utils.IkFkTransfer.execute() ( Line 2170 - switchTo() should be called with the switchTo of execute instead of the hardcoded ‘fk’ ),
Added as github issue: #406: When using anim_utils.IkFkTransfer.execute(), only baking to FK works correctly ( includes possible fix ) · Issue #406 · mgear-dev/mgear4 · GitHub
