Vendors, as well as others, should consider QuickMAT from Hogsoft. It makes MAT's for you directly from within Poser so the references are taken from a Poser-created file. It will also capture an image (even a rendered image), and builds both the .rsr and the .png - and all "on the fly." Even if not using QM, then simplying running CorrectReference Pro before zipping the product, would find and fix any malformed references... Many of Hogsoft's products are designed as much for vendors' use as for end-users.
