There are a few solutions to this: 1 - make the decoding part or RTEncoder into a script (algorithm is described in the help text) that looks if the gemetry file it needs exists and if not does the conversion as part of the load process.

As freebie can be in freeie section in the protected Poser download area. This would be a general solution for any mods and alterations developed from Poser material. 3 - Make La femme mesh a merchant resource like Paul/Pauline's
