Hello Everyone.
One possible solution to clutter, without increasing file size is to allow multiple download links to a single item. If the item is a 3D model, the uploader could have one link to 3DS, one to OBJ, and one to Poser, and another to DAZ Studio. If they uploaded a floral print texture, they could have one link in blue, one link in red, one link in B&W, and one in “All of the above”. This would help keep down the number of items at the site, and allow the user to select exactly what they need. The list of file formats was not meant to be complete, just a few formats that come to mind.
