So, i have written the .pc2 exporter located here: (atm)
https://svn.blender.org/svnroot/bf-extensions/contrib/py/scripts/addons/io_export_pc2.py
(install as an addon)
I tested the output files with Maya and there it works.
But before committing the script it would be nice if other apps (3dsmax?)
which can process .pc2 files could be tested too.
Thanks to Matt Ebb’s efforts on his renderman exporter
this exporter can now also do oversampling
unlike the old 2.49 exporter, which only did whole frames.
So, please test
and post if something doesn’t work.
Edit: updated the link to a newer version in svn/contrib
