Quote - @ ADP, have been playing with version 1.42 and like LatexLuv and ayanematrix have been unable to get the results you posted. Have had a look at the workers folder, is it possible that the compiled versions of PoserLuxExporter_workers and BBLuxMat were not updated in the last package update?

I'm thinking that's the case. I looked a bit further into the code and some of the export functions relating to metal and glass are not defined specifically, but velvet is. On the plus side, it also appears that using the skin node works too and is mixable with velvet.
