Apparently you can edit the .cr2 file to change the version number of a file. There is a string about it further down, a few days old. Open the .cr2 in a text editor and change the "4.1" back to "4". I haven't tried it yet, but it sounds like a useful trick. I don't know anything about the half-dragon, unless you are referring to the disappearing legs problem with some of the integrated figures.... Turn off IK for the legs if that might be the problem.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
