One thing that perfly does is to call pfdCombineLayers wich actually
forces all your pfLayer mode to DISPLACE instead of STENCIL!
This might explain the results you are getting.

The bad news is that there is no command line option in perfly to disable
this behavior so you will need to comment it out and recompile.
pfTeam: It would be nice if perfly would ship with a command line option for
this which could be on by default.

Which version of Performer are you using exactly?
