I'm not going to comment on the actual question, but I want to make it clear
that LDView should NOT display the logo mirrored, ever. It automatically
detects that the stud has been mirrored, and mirrors the logo back to its
correct orientation. For this reason, you cannot use LDView to detect the
mirroring if you want to proof a part and verify that there aren't any mirrored
studs. (If some part author wants an option to turn off this auto-unmirroring,
please let me know; it should be trivial to add.)
LDView can do this because it fully parses and processes the model tree. On the
other hand, my understanding is that L3P essentially converts the model tree to
POV format one .dat file at a time, without any concept of the orientation of
the final rendering. This produces much smaller POV files and takes less time
to process.

| There is somewhat of a disagreeance going on over at the PT about mirrored parts and I thought I'd bring it to the whole community to discuss. Here's a little background for the non initiated: In order to same time and DAT code if a part has a (...) (21 years ago, 1-Jul-03, to lugnet.cad.dev)
