captainbuckfish Posted April 7, 2020 Share Posted April 7, 2020 Been trying to rig in Houdini, went through the rigging series which was decent but the script for Matching FKIK comes up with an error when I execute it. If you didn't see the video series. This is on the last video. Inside the HDA there is a parameter button created with the callback script hou.pwd().hdaModule().matchIK(kwargs,"arm") This is the code def matchIK(kwargs,type): if kwargs["script_parm"][0] == "L": side = "L" else: side = "R" prefix = side + "_" + type asset = kwargs["node"] bone1 = hou.node(asset.path() + "/" + prefix + "bone_1") bone2 = hou.node(asset.path() + "/" + prefix + "bone_2") fkcontrol1 = hou.node(asset.path() + "/" + prefix + "_bone_1_ctrl") fkcontrol2 = hou.node(asset.path() + "/" + prefix + "_bone_2_ctrl") fkcontrols = [fkcontrol1, fkcontrol2] bones = [bone1, bone2] if type == "leg" prefix = side + "_" + "foot" bone3 = hou.node(asset.path() + "/" + prefix + "_bone_1") bone4 = hou.node(asset.path() + "/" + prefix + "_bone_2") fkcontrol3 = hou.node(asset.path() + "/" + prefix + "_bone_1_ctrl") fkcontrol4 = hou.node(asset.path() + "/" + prefix + "_bone_2_ctrl") bones.append(bone3) bones.append(bone4) fkcontrols.append(fkcontrol3) fkcontrols.append(fkcontrol4) for i, fkcontrol in enumerate(fkcontrols): curbone = bones bonepath = "/".join(curbone.path().split('/')[2:]) iksolver = curbone.node(curbone.parm("solver").eval()) chopstring = 'chop("' + iksolver.path() + '/' + bonepath chans = ["rx", "ry", "rz"] for chan in chans: if abs(hou.hscriptExpression(chopstring + ':' + chan + '")')) < 0.0001: rot = 0.0 else: rot = hou.hscriptExpression(chopstring + ':' + chan + '")') if not fkcontrol.parm(chan).islocked(): fkcontrol.parm(chan).setPending(rot) Error says line 16, in matchIK AttributeError: 'NoneType' object has no attribute 'path' Im fairly clueless when it comes to scripting just wanted to be able to match IK Fk. Help would be appreciated as would any advice on places to start with python scripting. Many thanks, Duncan Quote Link to comment Share on other sites More sharing options...
DaFiNNiGaN Posted June 14, 2020 Share Posted June 14, 2020 (edited) Just make sure you are accurate with your typing out. The line above it has an error which prevents working through the list of bones. curbone = bones It should be: curbone = bones[i] Edited June 14, 2020 by DaFiNNiGaN Quote Link to comment Share on other sites More sharing options...
