Quote - I dont think that offering a group of textures at 1024x1024 is going to add that much to a file, nor do I think it would deter me from downloading it.

Texture packs are often loaded to the hilt. Renderosity has 70MEG size limit. Adding low rez set of maps would often mean having to provide one less texture in the package.
Also it adds to the work a vendor has to do, because  second set of material collections and poses needs to be created.
Most vendors already put more time and effort in the product then the money they can recover for it, so at some point they have to draw the line at trying to accomodate all possible users.

AFAIK, most vendors are under the impression that most poser users are interested in higer quality, higher res. textures.
