I'm having the same problem with parts 6551 and 71427c01. I also have read through those two threads, but I'm running into an issue in step 5 of Trevor's instructions in the first thread.
When I navigate to my unofficial parts directory, I see a "fade" directory and a "Parts" directory. There are "parts" and "p" subdirectories under the "fade" directory, but no "fade" subdirectory under the "Parts" directory.

I have not seen any indication of the lpub3dldrawunf.zip archive being updated during processing of my mpd file.
All the rest of the fading appears to be working correctly, and those parts render correctly unfaded, but I can't get them to render faded.
