i was about to post exactly the same!
i'm not interested in pay items - for this, i can go to renderosity or daz3d (their quality, at least, is guaranteed).
and since the shop opened, the 3d model section gets every day new models of a type i don't appreciate - barely clothed "ladies" for i dunno what platform - an eye sore imho. does sharecg now cater for weirdo wanky sites? if i want weird, i can go to a [censored] site - which i don't.
so i'd love to skip all this - PLEASE add an interface button to show only free - or pay - or all items.
btw, not adding a button won't change anything in my customer behavior, i.e. i WON'T buy, but my site experience will be accompanied by negative frustration and a waste of time every time, and instead of recommanding your site bringing new members/viewers, which i guess would contribute to your ad revenue, i might rather start complaining about it, with the opposite effect.
let's be honest, we're all here for the freebies - with the OPTION to donate to the creators/artists. if i could afford to pay for my items, i would do so on the 3d sites mentioned above, or similar places... and i CAN'T afford more than food these days, so...
