Funny enough I actually have written those helper scripts since it was
pretty simple as their JSON files are quite well formatted. Honestly I
never really looked further than ngSkinTools as they're the most complete
and functional skinning toolset I've come across and used for many years.
Apologies as this is quite old code and not very well structured:
import json
import maya.cmds as mc
def copy_bind_from_ng_file(file):
""" Copies skinCluster from ngSkinTools JSON file to make the same
skinCluster before importing weights.
Args:
file (str): file...
Returns [str]: list of influences that we used to build the skinCluster
Usage:
copy_bind_from_ng_file('path_to_your_ng_skin_tools_weights_file.json')
"""
influences = []
missing_influences = []
with open(file) as f:
data = f.read()
json_data = json.loads(data)
f.close()
for value in json_data['influences']:
influence = json_data['influences'][value]['path'].split('|')[-1]
if mc.objExists(influence):
influences.append(influence)
else:
missing_influences.append(influence)
if missing_influences:
print 'Missing Influences from your file:
\n{}'.format(missing_influences)
result = cmds.confirmDialog(b=['OK','CANCEL'], m='You have %d missing
influences...continue adding skin cluster from file with %d influences?' %
(len(missing_influences), len(influences)))
if result == 'OK':
mc.skinCluster(influences, mc.ls(sl=True)[0], tsb=True)
return influences
