no, there is no direct way to omit certain types from being written out.
You could write and register a class that takes responsibility for
writing out VoidPAttachments, but does not really write anything (or
perhaps a dummy value) and on read back simply does nothing. You can use
OSGNFIOGenericAtt.{cpp,h} as an example for another type of attachment
that get special handling instead of using the generic code path.
Another alternative is to make a pass over the scene after loading and
just remove all the VoidPAttachments, not very nice, but it should work.
Cheers,
Carsten
