- Fixed potential crash loading assemblies. 
- Fixed issue when saving an mxs file with the "save as" option which launched mxcl.
- Fixed "save as" option when the extension is in lower case.
- Fixed triangle groups exportation. Now SolidWorks faces are exported as triangle groups only if the material applied to the face is different to the material applied to the body. It is very useful to select SolidWorks faces within Studio.
- Added render setting to choose whether SolidWorks exports spot lights or not.
- Fixed some situations when some render parameters could become corrupted when read.
