I'm starting to see files put together with RTEncoder for the newer characters of Poser.  These files have an rte extension.  Although I haven't tried it yet, it looks like it works in the same manner as ObjactionMover, requiring the original "seed" file.  If you need it you will find it here:

Important note: Be sure to download version 1.01.  This is a release version.  Version 2 is for alpha testing only.

Version one is windows only.  Version 2, when complete will be cross-platform.

Than you melamkish, yes it works exactly like objaction mover,  it's a less popular format made by Russel of posrpros.

I had to use to decode the obj file for New Judy model.
RTEncoder is much like obj mover.

Major difference is that Mover can work with OBJ files only, RTEncoder has no knowlege if the file internals that it is working with, so it can work with any two files, using one file as the key and the other as plain text to be encoded.
