@Trekkie-

"V4WetCreator" was a kind of MAT pose thing that put a "wet" sheen on V4, like what would happen if you went out swimming or something similar.  It was supposed to go over whatever normal textures you already had over your figure and was even had differing levels of wetness including a setting called "Drenched".  The original author of the MAT pose was someone going by the name "Mackie Messer" and it (according to the readme file I found) was copyrighted in 2008.  

If that ZIP file is still out there in the wild, then it should be avoided at all costs.
