Sorry for my bad english.
If you can wait, in archiradar-Link there are a lot of good links (but now it 's out of order as you can read at the top fo the page). You can look for some adresses in Forum- Segnalazioni e Suggerimenti (This is a forum where it is possible to signal web sites where you can find tutorial, library, texture, free or not, for ArchiCad and Artlantis)
Besides, you can look for some object in:
http://www.idc.ch/archicad/go to "Zusatzprodukte" -Artlantis - Artlantis Shader
some of these links (texture, BB) are free.
