@imdjs Last year I posted an error image that I received before Blender crashes, when trying to run the operators from this addon.
I just downloaded the addon again and tried it in the daily build, and 2.79.0 stable build.
I currently receive a python errors but no crash.
I’m receiving 2 separate but similar errors when pressing F/Ctrl+F vs Ctrl+X
The first error I receive is this:
F / Ctrl+F
When changing __init__.py line #68
to
if(getattr(LG, 'CL条序L4f3乛画LG', [])==[]):
I get this error/report from __init__.py Line #83

self.report({"ERROR"},"this is the old version of setting need to reset bone ik!!");#"INFO" "ERROR" "DEBUG" "WARNING"
And this is the second error:
Ctrl+X
When changing operator_twist.py line #41
to
if(getattr(LG, 'CL条序L4f3乛画LG', [])==[]):
I get this error:
When I change operator_twist.py Line #49
to
if(getattr(G, 'cvpSC', None)==None):
or
if(getattr(G, 'cvpSC', True)==None):
I receive this error:
but then something in Blender gets stuck and everything lags and break, and the only fix is to exit Blender.
The python files are filled with Chinese text, making it VERY hard to read and very difficult to try to fix for myself.
I want to give this addon a legitimate try but the errors prevent any usage, whatsoever.
