It was great. And meeting other users previously known only on-line was fantastic too.
I'm eager to see what Rob told us they are doing and what he already showed in the meeting. This Siggraph will be quite something if they manage to show as much as he explained. If not all, well, next time (release or show) will be amazing too.
Edit: I wanted to thank Rob for coming to Barcelona and talking to us, and to FXAnimation School for hosting the meeting and organizing the whole event (restaurant included). All in all it was great. Thanks.
