The sole texture required by the shader.  The forum will reduce and compress this thing.  As a 600+ kb 2048 square jpg, it is too large to post properly.  The point, if there is any, may be that this is the only texture used by the shader.  It is easily adjusted for GC.  Everything else is the problem... but the "everything else" is the body of the letter, Jameson.

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.
