Edge transparency "EdgeAlpha" of a patch

Is it somehow possible to specify the edge transparency for the edges of a patch separately for each edge at a time?!?! ... I have a problem where I need to make one or more edges transparent in some patches ...

Thanks for the answer in advance!

Best Regards,

Yes -- just not as nicely as one might hope.

"'flat' — Use a different transparency for each edge based on the values in the FaceVertexAlphaData property. First you must specify the FaceVertexAlphaData property as a vector containing one transparency value per face or vertex. The transparency value at the first vertex determines the transparency for the edge."

The FaceVertexAlphaData property?

I can't find such a property...
