All the downloads I've had from there have had 3DS meshes in them as well as the GSM version (which is an ArchiCAD Library Object, incidentally). I couldn't be sure that was always the case, but don't be put off downloading because of it. You certainly don't need an ArchiBar - doesn't work in Opera anyway. :) One of my downloads didn't contain what it was supposed to, but there wasn't anything suspicious; just a case of mis-packaging, I guess.

Quote - Some nice stuff, but 3ds props seem rather plasticy in Poser, it there is such a word.

There's nothing about 3DS meshes which would make them more or less plasticky than anything else. However Poser tends to assign its own default materials to imported meshes, which always includes a lot of specularity. Get rid of that, a bit of work in the material room, and you should have something perfectly usable.
