Thanks Stephen, very useful info. Your post are ten time more useful than the site who shall not be name! 🙂
The Softimage Mailing List Archive, the si-wiki, the si-community, the xsibase, the cgtalk-softimage or did I intentionally miss at least one? 😀
You miss the “who shall not be name” one! 😉
Just getting started with Softimage 2013. Trying to do a few tutorials, I noticed that the download links don’t work at http://softimage.wiki.softimage.com/index.php?title=Face_Robot_Learning_Movies
The downloads start but never complete, stating “Network Error”. There’s not really any contact info on the wiki so I thought I might as well post this comment here.
