Just make sure you use the default LH obj files, since they are welded at the seams. ZBrush automatically welds any duplicate vertices and changes the vertex order so you should always start with a "solid" object vs one broken into body parts (which happens whenever you export an OBJ from Poser). 

And yes, it's still for sale. ZWrap 2024.6.2 is for older versions of ZBrush and it's the version I use.  Still for sale at faceform.com

For the record, that's what I've been using to make Texture Transformer packs to convert textures from/to G1, G2F, G2M, G3F, G3M, G8F, G8M, G81F, G81M, V4, M4, LH1, LH2, LF1 and LF2. Been giving it a lot of use lately. LOL
