OpenSkin export fails. The following is in the default.log:
[2016-07-13 16:35:43,549: ERROR/MainProcess] Task remapp.exports.rf_export.rfopenskin[16c6caf1-f8d9-4ec4-b951-d6d1091bad77] raised unexpected: AttributeError("'NoneType' object has no attribute 'code_meaning'",) Traceback (most recent call last): File "c:\python27\lib\site-packages\celery\app\trace.py", line 240, in trace_task R = retval = fun(*args, kwargs) File "c:\python27\lib\site-packages\celery\app\trace.py", line 438, in __protected_call__ return self.run(*args, kwargs) File "c:\Python27\Lib\site-packages\openrem\remapp\exports\rf_export.py", line 1070, in rfopenskin if "Copper" in filter.xray_filter_material.code_meaning: AttributeError: 'NoneType' object has no attribute 'code_meaning'
It seems that the export routine can't cope when there is no filter data.
The reason I was trying to export this was that the in-built openSkin calculations failed - possibly for the same reason.
